Hello ...Can anyone advise if resetting the ECU will erase the programming for the DRLs, Remote window/sunroof features, etc?
I intend to reset my ECU but considering I had to pay the dealer to program these functions, didn't want them to be erased.

Any assistance would be appreciated.

Thanks

 

No, a user 'reset' (disconnect battery, foot on brake for 10sec) supposedly just removes the computer 'learning' re: driving style. It definitely won't erase your programming preferences.

 

Excellent, thanks for the response.
