Hi guys, I have a 2015 A3 tdi, it is the 185bhp engine. The problem is starting first thing in the morning, takes 3-5 minutes!! I have had it in to an electrical specialist but the only thing he found was no compression on number 4 cylinder. He said the only thing he could think could maybe be a sticking valve but was his best guess. I have read about fuel going back into the tank on another thread but was the older model. Any ideas or ways of testing to rule things out before I go stripping heads down, thanks
Forgot to mention once it does fire up, it drives and starts fine.
