Hello, I have 3.0tdi BKN Manual A4. When its all warmed up fully and i go and stop it, and wait say 10 minutes and start it again it will do half a crank over and then kinda sticks then speeds up again.

It goes with a clunk when it does it, almost seems like it hydrolocks itself. Could it be a leaking injector and then fills up the bore?

It never does it when its cold tho but it takes a while to build fuel presure if left over night.

Just ran vcds on fuel pressure, 220bar at idle and when turn of wait 30 secs goes to 0.0bar
