	EPC after tuning « on: December 29, 2018, 06:00:16 AM »

Hi.
I had a guy to tune and immo off on a 2000 Audi A6 C5 1,8t apu engine. He programmed a used box from Ebay with same part#4B0906018AA.
Car starts and run so that's not a problem, but have EPC light on and code from cluster 01177 no contact with ecu.
The guy that tuned say maybe problem with the ECM it self, I tested that in the car before sending it out and no EPC light or no contact ecu from cluster.
Any ideeas?

Thanks and happy new year.
Svein

pull it with bootmode (or nef if it isn't protected) flash back to stock.

if you still have the EPC its the ecu. If not, your tuner screwed something up.

Also verify the engine coding is correct for your car.
