Hello there, a friend of mine did some modifications (Egr off, dpf off, some more juice). Now I am getting some intermittent service warnings during acceleration. It happens when the car is cold and less frequently when it is warm. Any advice what is wrong? He says everything is fine etc. I would appreciate any help, there is no sign of stored error in the memory (opcom). I hope the modification is ok. Thanks.

Tell your friend he can't make files and go to a tuner that really understands and you won't have these problems :)

Does above means you did shitty tune? :D There are lot of guys here to tune EGR and DPF off correctly - just ask kindly.

OMG. Yes, this is a shitty tune. I spent couple of hrs to check the differences. I counted more than 30 alterations, real magic. Holy cow, there ain't that amount of maps I believe. I cannot upload ori file since the DPF is removed. To whom my I send my kind feelings? :angel: :geek:
