KW: 2011 Q5 2.0, Misfire, then crank, finally no start
Hello,
2011 Q5 2.0 Petrol, 219,000 km.
Recently serviced the transmission's mechatronic unit with a repair kit. Gearbox error code is gone. So the car was setting for a while. It worked perfect until I tried to test the transmission, but the car started to misfire on one the two cylinders (namely #4), then it only cranks now.
Inspected fuel supply, plugs, most sensor, swapped coils, cleared codes, retested, no good. Last error codes were P0354 and P0351.
Tested the accused coil (#4). It was Ok. Did another coil swap, changed Cam sensor, nothing changed. Only progress in all this it cranks now longer rather a quick short one.
Looked in many forums and clips. Nothing similar it seems.
What am I missing something? Any educated advise, please?
Kay

I'm posting an update since I could not edit/delete initial post.
