Flash back to stock

[Aiglesias10]

Hi Guys, I flash my car with a local, I dont like the flash because there is presenting some errors , and I want to put my car stock again but not with this Guys, its posible to put my car stock again with a diferent tuner? Or Maybe in the local bmw dealer.

I would not trust a dealer to do it. Do you have MHD, BM3, etc? Do you know what they used for the tune?

Yeah that info is vital. I would be wary having someone blind tune with no backup. Best bet is to take it back to whomever tuned it. If all elsw fails be prepared to be financially scalded by bmw if they have to unflash it and hopefully its not under warranty

Not, its a flash with a local, dont know what they used but not mhd or bm3, I want to put stock again and put BM3 btw, I want to avoid taking it with them, I'd rather find another way to put it in stock

The local bmw dealer is charging me $ 300 to put it in stock, but I don't like being made to sign a document where they are not responsible if something happens.

I'd maybe reach out to Alex@ Alpine tuning to see if he could help you out if you haven't already gone the dealer route.

Do not under any circumstances take it to the dealer. It will flag a software tamper code.

Reach out to Alex at Alpine. He is the go to guy in this situation.

I know you stated that you didn't want to go back to them. But I would take it back to the original tuner and let them flash it back to the original since they didn't do it right.

You need to flash back to stock with the original tuner solution.

It appears that this is not known.

Alex will be able to determine the original software from vin and flash back to stock. When plugged in no tamper code will flag with standard dealer tools.

FYI the tamper code is just one way they would check to see if its tuned, they also check for the max recorded torque value in the trans and ABS computers, which is why so many people get voided even after flashing to stock when they go in.

Is it possible to clear the torque values in the transmission and ABS computers while flashing back to stock?

I'm aware.

Flashing back to stock will remove the obvious software tamper code but as they dig they will know you were tuned. How much they dig will depend on the cost of the warranty claim. Major drivetrain damage and they will find out.

Some have stated that with a bench flash it can be returned in its entirety to it's pre flash state but this requires opening of the ECU.

I'm not sure this is accurate.
