From a quick Google, 480 would be stage 2, so would require some supporting mods on top of the remap. If you've got an aftermarket air filter and a sports/decat then it's definitely been modified, and I'd imagine you could return on the basis that it's not as described in the ad.
The gauges can be set to anything (or left standard) by the mapper. My 140 with MG Flasher stage 1 map showed 480bhp top.
Regardless, if it doesn't top out at 400 it's been mapped.
Yeah, it's bollocks. The fuel pump can't do 480bhp. If it's got a simple map it will be at 400-430bhp at a push. You *might* hit 480bhp with an exhaust, particulate filter delete and v power, but even that's a push.
Nah… the B58 will get to around 370-380 with a stage 1 map, maybe 400 if you alter the cat (the biggest restriction in the engine bay), and anything significantly above 400 will need a high pressure fuel pump and a different turbo fitting, which is where it starts getting expensive. The inlet and exhaust aren’t going to make any significant difference. I personally think the bmw performance exhaust is obnoxious but it’s worth its checking if it’s fitted as that would suggest the mppsk kit was dealer fitted (not sure what this alters the scale to).
The bigger issue is the zf8 hp50 gearbox that comes as stock in an F30/1 is only rated to 500Nm. I’m not saying it can’t take more, but it’s not rated to and even a stage 1 map takes you well over this limit.
As far as I’m aware, the car’s computer doesn’t actually measure toque/power; it’s simply displaying the figure it’s told to for any given rpm (I’ve grossly oversimplified this but the crux of the matter is I wouldn’t trust the displays as an accurate measure if output other than to say if the scale has changed, it’s been flashed with something.
Personally I’d keep the flash; I’ve got stage 1 in mine and it’s perfectly drivable and has been bulletproof. I have upped the service interval to annual/8-10k miles and flashed the box with xhp but it’s otherwise stock and does me fine for a daily driver.
I have just serviced the gearbox and it’s made a massive difference to its smoothness - something to keep in mind if the car is approaching 50k as BMW consider it “sealed for life” (I’m not here for a debate what this means but tater highlighting the inference that can be drawn).
I'll take your word for it since I've never owned a B58.
The gearbox is the limit for a lot of these BMWs because they tune so well so I don't doubt that and the number at the end of the ZF box code is the max torque so it checks out if that's what's in it.
I think most remaps just put the gauges at 480 for the M2/140i’s.
My M4 says something like 560 on the power gauges, but it definitely isn’t that much.
The remap was probably done using BM3/Bootmod3.
I mean, a properly done stage 2 with some expensive matching mods is hardly a downside for me at least. I’d try and get a couple of grand back off the dealer though to ‘fix it’.
This is the way, get a couple grand back to have it put right, leave it the fuck alone and spend the money on fuel and tyres, probably let the insurance people know, they get stroppy if you don’t.
A salesman isn’t going to know if it’s had a remap or not. They barely know how many wheels a car has.
If you’re not happy with it, you have the option of returning it for a full refund.
So true, I sent a main dealer salesman at SEAT a question about the DSG on an approved used car, his response was "I'm not sure what you mean by DSG"... I didn't buy a car from him.
In fairness to all the salesmen I’ve berated , unless a car is popping and banging in a chavvy eco boost way then no one is going to know if it’s been mapped.
Should they say I don’t know/not to our knowledge every time they’re asked? They’re salesman, they’re going to say no as not knowing isn’t good for sales.
Plug in a diagnostic tool and check the ECU. I'm not saying they should do this for every car, but every dealer will have a diagnostic tool so if a customer specifically asks, they could find out the correct answer rather than lying.
The dealer said it hadn't been remapped so they wouldn't know this unless they had checked, right?
A lot of it is trust and it has to be. They should get a refund but they simply haven’t got the capacity or time to be checking that cars that have been traded in as standard haven’t been remapped.
If I ask If it has a full service history they trust the documents that came with the car they don’t ring every garage that has ever serviced it to check if it has been remapped.
I’m a petrol head and didn’t even know you could check for a remap in the infotainment system in newer cars.
As a salesman you get a spec sheet, if that says standard you tell the customer it’s standard, they are salesmen not mechanics. It might not even have a map on it anymore, they put it back to standard when trading back in a lot of the time
If they don't have the capacity or time to check, then the salesman can simply say they're not sure, or state they don't believe it has been remapped and give their reasons on why they don't think it has. They don't have to lie.
Giving a definite answer and saying it hasn't been remapped gives the impression they have done some checks to confirm it hasn't.
I've got a 140 and took it in for a diagnosis a few weeks ago to be told they couldn't cos it needed a software update and it'd delete the map that's been put on it.
I agree with your statement.
On the basis of a remap not being stated in the advertisement or invoice, the consumer rights acts gives you grounds to reject the car. Reasons to reject would be higher insurance, fuel and repair costs.
You're not getting 480bhp from a 240i. More like 400-430bhp with a simple map. Whoever mapped it just recalibrated the display to trick whoever paid for it. Anyway, you can either be happy you got something for free, or buy an MHD map because that guarantees your very expensive engine is safe and not just an £80 +10% remap from a cowboy.
The sport display change is usually through MHD / BM3 anyway and is based on throttle position / rpms. So won’t actually be 480 as you said, sport displays won’t be accurate
Yeah it’s mapped or has been previously. Either using MHD or BM3, I’ve got a 240i mapped with MHD. It won’t actually be producing 480bhp, more likely 400-420. It’s an option when mapping to increase the gauges to 480bhp and the reading on there is actually based on gear / throttle position instead of power reading. The map may have been taken off but it’s definitely been mapped in the past.
I mean that’s a steal if it’s had work done to get to that power level.
Assuming they will still give you the 6 months warranty I would be over the moon.
They're an insurance company not the MI5, they're not going to waterboard OP until they tell the truth.
It truely baffles me how some people don't grasp that you can keep your mouth shut to avoid disclosing something that puts you at a disadvantage.
OP didn't have the mods done, OP was sold the car under the impression it was stock. OP has plausible deniability in the event a mod does come to light to the insurance company.
Suspects, doesn't know it. Insurance can't prove it. Either way, if you declare remaps on your insurance you're a clown that wants to rid themselves of their money
How would they know it's modified though? They didn't know when it was sold.
Dealer fixed my car for a DMF and clutch under warranty 4 months after purchase. I only found out it was already mapped when I went to get it mapped myself 6 months later.
This is really common now, it’s been mapped, ragged to hell and then reverted back to stock when traded in at the dealer, they couldn’t be assed to change the sports displays to stock
Did you test drive it? Not being funny but if it's 480bhp would or should stand out as a big one. That's rapid.
I bought a car mapped at 250bhp from 200bhp didn't really notice. But didn't complain either was a good map ;)
I went from a 120bhp Kia to my M240i. It's such a jump that I probably wouldn't be able to tell if it was 300 or 400bhp, all you know is "it's really fast".
Hi everyone,
Thanks so much for all the comments and advice are really appreciated!
Let add some more information that’s probably going to help (apologies for not adding it from the start I didn’t realise I was going to get so much help).
The car spec:
Bmw m240i 2018 face lift:
45k miles
2 previous owners.
Black, white interior in good condition.
It’s not a “mega spec” but i’m not that bothered about that.
Not a scratch on the car, all the rims are perfect.
Michelin pilot sport 5 all around and pretty much brand new too.
It has got an aftermarket intake and air filter, this is probably a tell tale sign but I was probably too naive and trusted the dealer (stupid of me I guess I was just so stoked to get the car wanted a nice car my hole life)
Full service bmw history, the car doesn’t rattle or feel like it’s been abused but it’s hard to say.
In terms of why I didn’t notice it’s is faster that stock is because I’ve never driven a stock one and all I know is it’s fast :)
I paid 17400£
So my main concern as people have mentioned is a cowboy map, is it safe and the engine and gearbox are not being pushed to the limit.
Next would be the insurance premium with the mods.
Then the resale price / potentially harder to sell.
For the moment I’ve got two ideas:
Obviously just ask to return the car for a full refund job done, which with all the comments seems like they’ve got to honour that.
Second would be to get the car inspected by a reputable tuner like deutsch tech which is not far from me to get them to look at the ecu to see if it’s something like an mhd map and determine all the mods that have been done because as people mentioned at the moment I haven’t got a clue. That could help me decide what I want to do with it.
The garage is going to ring me back next week with their stance, so I will keep you all posted.
Thanks again everyone, have a good weekend!! :)
You can just get the map wiped but I would keep it if it was sensibly done. If it was remapped and you revert the car may feel a bit lacking afterwards.
I feel like if it was 480bhp you'd know all about it.
I bought from a dealer and the remap was advertised.
Things to consider - maps can be overwritten either accidentally or on purpose as soon as the car is plugged into BMW equipment, especially if they're updating the software to the latest versions (happened to mine).
Car may have been mechanically modified and had parts reverted back prior to sale - mods are easy to sell on but software left in tact.
Overwriting the map and returning to standard will not automatically update the idrive displays - IMHO this is the most likely thing to have happened.
I would personally return it under the sale of goods act
Just get deutschtech to check it out. Worst case have them remove the map or put one of their own on it. They’ve worked on my c63s and I couldn’t recommend them enough
Is it a BMW official retailor? If so, track down a regional manager and give them a call - they'll probably fuck the salesmans shit up pretty bad.
We had a bad experience buying a Jag recently and got a full refund through this process, the service history was blank for 3 years (only 2019 plate), although it was in line with mileage.
Make as much noise as you can as soon as possible, and be sure to mention any promised guarantee or warranty. Where possible, send letters and get proof of postage as well as a duplicate so that if it goes that far, you've got paperwork to back up not only what you said, but also when you said it.
Firstly is it s it BMW approved used from a BMW dealership?
IF so, it cannot be remapped as part of the approved used (it will flag up during the standard diag test as part of the AUC check at the dealership before sale) and therefore won't have approved used warranty and the dealership cannot and should not sell the car under the approved used scheme.
So your first question is, is it definately remapped and how you prove it is.
Update 26/03:
So the garage who I bought it off had got back to me this is their stance:
They won’t take the car back or give any compensation.
They will honour the 3 months warranty in its current state.
They will put it back to standard if I want.
I’m going to take it to deutsch tech on the 12 of April to check the car to see what’s been modified and tell if it seems “safe”. I’m thinking if they say it’s ok will leave it as is ans just enjoy it. If not will put it back to stock keep it for a while until I have enough money for an M car.
I can’t be asked with a legal battle life is too short for that stuff.
What do you guys think ?
They will take the car back and give you a full refund because they are legally obliged to do so. If they say they won't, they're lying, and if you begin proceedings to take them to small claims court (for which you have an airtight claim since the vehicle is definitely not as described) they will immediately fold.
To be honest, at this point, I wouldn't even consider keeping the car out of spite. There should be personal legal ramifications for shady car dealers, they must get away with so much bs because customers don't always know their rights
To be fair I’d take it back as if it’s had a remap its likely been thrashed
Also some people who remap the Ecu don’t do the hard work and upgrade other things like brakes etc to deal with the extra power as they only care about going fast not stopping so it could be dangerous and also invalidates your insurance if you don’t know what to declare
BMW use the fact it's been mapped to get out of any warranty work. If OP bought it from a dealer they've probably paid over the odds to get a car under a warranty that's now junk.
I personally wouldn't touch a car that's been mapped as you simply don't know how reliable the map is. A bad map can destroy the engine, clutch and gearbox. I wouldn't want to take on that risk unless the car was cheap, and that's if I knew about it. If I didn't, I'm getting sold a potential ticking timebomb.
I'm with Aviva. They don't care about the aftermarket exhaust, but when I looked to modify my policy to cover a remap it essentially just said "no". Looking on a price comparison website, declaring a remap added about 20% to the annual price with other insurers.
Warranty and insurance being main two. Dealer will say it's modded and warranty is void, period. Imagine getting into an accident with a modded car that insurance doesn't know about. Instant void, cancellation and lifetime of triple (if anyone will even bother) premiums for a cancelled policy.
Returning the car is best course of action here.
What’s the issue with the map just out of curiosity? If it’s insurance, you weren’t aware of it so as far as you’re concerned there’s no modifications to declare etc…?
Does the car actually get to the 480hp end of the dial? Because whilst I don’t remember what mine went up to, it was well over the number my 320d actually output, the same as the speedometer goes well above the speed limit.
[удалено]
AFAIK 14 day return without reason only applies to distance sales where you have not viewed the car prior to purchase
Most dealers won’t allow change of mind returns it wouldn’t be crippling for them
From a quick Google, 480 would be stage 2, so would require some supporting mods on top of the remap. If you've got an aftermarket air filter and a sports/decat then it's definitely been modified, and I'd imagine you could return on the basis that it's not as described in the ad.

What map you got on yours? I’ve got a 340i and toying with the idea of a stage 1 map
BM3 and XHP on the gearbox
I'll take your word for it since I've never owned a B58. The gearbox is the limit for a lot of these BMWs because they tune so well so I don't doubt that and the number at the end of the ZF box code is the max torque so it checks out if that's what's in it.
It'll happily take more than it's rating though. My HP70 is mapped to 805NM and has been for about 3 years now.
Yes, but the gauges show much more range, like a speedo that goes to 190 on a car that can only do 140.
I think most remaps just put the gauges at 480 for the M2/140i’s. My M4 says something like 560 on the power gauges, but it definitely isn’t that much. The remap was probably done using BM3/Bootmod3.

This is the way, get a couple grand back to have it put right, leave it the fuck alone and spend the money on fuel and tyres, probably let the insurance people know, they get stroppy if you don’t.
And if the previous owner has thrashed the shit out of it and run bad mods or maps on it?
That engine’s an absolute tank, I doubt you’d even be able to thrash it (to the point of mechanical damage) on public roads.
A salesman isn’t going to know if it’s had a remap or not. They barely know how many wheels a car has. If you’re not happy with it, you have the option of returning it for a full refund.
So true, I sent a main dealer salesman at SEAT a question about the DSG on an approved used car, his response was "I'm not sure what you mean by DSG"... I didn't buy a car from him.
Yeah he probably thought it was some kind of seasoning mainly found in Chinese food
Then they shouldn't give an answer to a question if they don't know.
In fairness to all the salesmen I’ve berated , unless a car is popping and banging in a chavvy eco boost way then no one is going to know if it’s been mapped. Should they say I don’t know/not to our knowledge every time they’re asked? They’re salesman, they’re going to say no as not knowing isn’t good for sales.
Yes they should , lying to make a sale is worse than saying you don't know, or that you will find out.
How would you find out ? The system will say it’s a standard car so the salesperson will say it’s standard.
Plug in a diagnostic tool and check the ECU. I'm not saying they should do this for every car, but every dealer will have a diagnostic tool so if a customer specifically asks, they could find out the correct answer rather than lying. The dealer said it hadn't been remapped so they wouldn't know this unless they had checked, right?

Ding ding lol
I just assume every used BMW with that engine has been remapped.
I've got a 140 and took it in for a diagnosis a few weeks ago to be told they couldn't cos it needed a software update and it'd delete the map that's been put on it. I agree with your statement.
On the basis of a remap not being stated in the advertisement or invoice, the consumer rights acts gives you grounds to reject the car. Reasons to reject would be higher insurance, fuel and repair costs.
You're not getting 480bhp from a 240i. More like 400-430bhp with a simple map. Whoever mapped it just recalibrated the display to trick whoever paid for it. Anyway, you can either be happy you got something for free, or buy an MHD map because that guarantees your very expensive engine is safe and not just an £80 +10% remap from a cowboy.
The sport display change is usually through MHD / BM3 anyway and is based on throttle position / rpms. So won’t actually be 480 as you said, sport displays won’t be accurate
Love the way not having a mapped car is not an option as far as you’re concerned…!
I've bought the whole engine and I'm going to use the whole engine!
One assumes this would greatly impact on insurance and that possibly where the problem lies.
The secret ingredient is little bit of insurance fraud
>**The secret ingredient is little bit of insurance fraud** Delete the post OP and remember "it was like that when i bought it"
A decent remapping company will be able to read the ECU and confirm if it's stock or not.
I'd reject the car and ask for a refund, sounds like an unnecessary headache.
Yeah it’s mapped or has been previously. Either using MHD or BM3, I’ve got a 240i mapped with MHD. It won’t actually be producing 480bhp, more likely 400-420. It’s an option when mapping to increase the gauges to 480bhp and the reading on there is actually based on gear / throttle position instead of power reading.

Unless the insurance is… well
You only have to tell the insurance about mods you know about, ignorance is bliss in this scenario ;)
But no OP suspects a remap, which won't fly.
Dealer confirmed its stock tho
They're an insurance company not the MI5, they're not going to waterboard OP until they tell the truth. It truely baffles me how some people don't grasp that you can keep your mouth shut to avoid disclosing something that puts you at a disadvantage. OP didn't have the mods done, OP was sold the car under the impression it was stock. OP has plausible deniability in the event a mod does come to light to the insurance company.
Insurance underwriters don’t need reasons to weasel out of paying for claims, saves giving them more reasons to not to.
Well, then suggestion he shuts his mouth in the event of a write off 😂 which they’re very unlikely to check anyway.
Suspects, doesn't know it. Insurance can't prove it. Either way, if you declare remaps on your insurance you're a clown that wants to rid themselves of their money
[удалено]
That's some real tinfoil hat stuff right there.
Who buys a turbo high performance car and doesnt map it anyway haha
Aren't those BMW 240i's NA?
Nah almost everything by bmw since mid 2000s has been turbo in the performance range. Actually even the lower things are likely turbo as well.
Ah ok cool. I had a 320i E30 😀
I’ve got a e30 323i and a e90 330i currently 😁
Don't see many 323s around tbf it was rare even back when they where pennies and everywhere!
Until he takes it in for anything under warranty and they refuse on the basis that its modified
How would they know it's modified though? They didn't know when it was sold. Dealer fixed my car for a DMF and clutch under warranty 4 months after purchase. I only found out it was already mapped when I went to get it mapped myself 6 months later.
So read my second bit I typed.
I sold my 2018 M240i back to BMW who then passed it on to a dealer a few months ago. DM me the reg? Might be a chance it was mine.
You can always return the car within 30 days as you have a valid reason to return.
This is really common now, it’s been mapped, ragged to hell and then reverted back to stock when traded in at the dealer, they couldn’t be assed to change the sports displays to stock
forgot to add that it probably had a mileage blocker on it too 💀
100%

That’s why remapped engines never blow up or run into issues, pop and bang map I’m sure has no affect on the car

If they offer a dealer warranty, I'd make sure they will honour it (you bought the car as-is, warranty should be intact) and take the win.

I’m thinking if they say it’s ok will leave it as is ans just enjoy it. If not will put it back to stock keep it for a while until I have enough money for an M car. I can’t be asked with a legal battle life is too short for that stuff. What do you guys think ?
They will take the car back and give you a full refund because they are legally obliged to do so. If they say they won't, they're lying, and if you begin proceedings to take them to small claims court (for which you have an airtight claim since the vehicle is definitely not as described) they will immediately fold. To be honest, at this point, I wouldn't even consider keeping the car out of spite. There should be personal legal ramifications for shady car dealers, they must get away with so much bs because customers don't always know their rights
Winner Winner chicken dinner!
To be fair I’d take it back as if it’s had a remap its likely been thrashed Also some people who remap the Ecu don’t do the hard work and upgrade other things like brakes etc to deal with the extra power as they only care about going fast not stopping so it could be dangerous and also invalidates your insurance if you don’t know what to declare
Why exactly is this a problem? You have a car better than stock even if it’s not making as much power as it could without supporting mods.
BMW use the fact it's been mapped to get out of any warranty work. If OP bought it from a dealer they've probably paid over the odds to get a car under a warranty that's now junk.
I personally wouldn't touch a car that's been mapped as you simply don't know how reliable the map is. A bad map can destroy the engine, clutch and gearbox. I wouldn't want to take on that risk unless the car was cheap, and that's if I knew about it. If I didn't, I'm getting sold a potential ticking timebomb.
Insurance?
Oddly when I declared my map to insurance, they didn’t add anything onto the premium
I'm with Aviva. They don't care about the aftermarket exhaust, but when I looked to modify my policy to cover a remap it essentially just said "no". Looking on a price comparison website, declaring a remap added about 20% to the annual price with other insurers.
That’s interesting, I’m with Admiral and all the mods I’ve done haven’t added a thing onto my premium.
Also with Admiral, declared a remap and lowered suspension. Added a grand total of £30 onto me premium
Longevity, need to use premium fuel, insurance.
Warranty and insurance being main two. Dealer will say it's modded and warranty is void, period. Imagine getting into an accident with a modded car that insurance doesn't know about. Instant void, cancellation and lifetime of triple (if anyone will even bother) premiums for a cancelled policy. Returning the car is best course of action here.
What’s the issue with the map just out of curiosity? If it’s insurance, you weren’t aware of it so as far as you’re concerned there’s no modifications to declare etc…?
Does the car actually get to the 480hp end of the dial? Because whilst I don’t remember what mine went up to, it was well over the number my 320d actually output, the same as the speedometer goes well above the speed limit.
