I can hardly believe that a brand new car with less then 1000miles on it has a real problem.

This problems happened right after I installed a RaceChip Ultimate, but they wont go away, I already removed the RaceChip.

PS.: I can not control the Front Assist By the MMI, I can not deactivate the ESC by the MMI even though everything is working fine, I did test all functions driving the car, ABS, ESP and front assist works fine. The only funtion that is not working is the Start-Stop system.

It shows an error on the Car.

There is no fault light on, The only way to know about theses faults is scanning with VCDS.

Thanks much for the help!!!

I'd go back to the manufacturers of the racechip and check they tested it on a car with the same features as yours!

Post by: alexbach on 21 August 2014, 13:13: I did try to clear them using the VCDS but no success. I brought it to a dealer he disconnected the battery for couple minutes qnd put it back, but the errors stayed there, he sayd he would need to send the report to the manufecture and work with them online.

I got in touch with the RaceChip personnel and they as for some pictures of the racechip installed, send it to them, they said it looks alright. They are waiting on what the car manufeture will say.

Im going to try to disconnect the battery myself and see if I get different results.

Thanks guys. Please keep sending me more ideas if you have.

I tried the battery deal, disconnected it and left of for an hour, the faults still there, cleared the new faults that appeared but the old ones remains there.

any other suggestion?

thanks

Post by: alexbach on 21 August 2014, 18:27: Good call. I did check if it is seated properly but haven't checked if the pin are still in the right place.

Do you think is there a chance that the RaceChip installation could have f**ked up my sensors?
