2007 q7 wont start and Epc light on
I have a 2007 q7 3.6L (gasoline).
Somtimes the car wont strat and the epc light comes up.
I took it to the garage and said it was a communication problem between the ECM and the engine computer( or somthing) so i changed the relay of thr fuel pump( it was coded 614 and was grey). The car worked for a month and a half then the same issue happens.
I wen to another garage and said it was another relay,this time for the engine computer. It worked for almost a month and a half and the issue is happening again.
I still have the battery from the company, i checked and was ok.
What could be tge problem?
Thank you for your help
