Carbon Cleaned and now Emissions Light is showing...

electricfurnace · Nov 6, 2016

2007 B7 RS4 saloon, engine was carbon cleaned a few weeks ago and now the emissions light is on. It was cleared once but is now back on.

Any ideas?

Do any other adjustments need to be done, such as MAF sensors etc?

Cheers

I had a similar problem kind of. After clean and remap, cel came on 1 day later. Scanned the car and it was B2S1 lambda sensor faulty. Kinda strange but maybe after the clean the car somehow baggers the sponsors?
