so it is a knock, miss, cough, spit, struggle for about 4 seconds when I am starting the car in the morning if I just turn the key with the clutch depressed, unless I give it some gas.
the coolant level is stable and although it is losing a little bit of oil I am pretty sure it is leaking on the outside of the engine (maybe under the timing belt side cam cover) the dipstick has not raised and the car seems to run perfectly well once it is over this hiccup.
I cannot see any obvious air leaks (there is not a lot left to leak)
I have tried to let it prime twice this morning in case it was lack of fuel, and it was maybe actually worse this morning (or progressively getting worse?)
any ideas?
I was thinking about
1. checking the catch can
2. resyncing the throttle body
3. clear fuel trims adaptions <-- could it be too much fuel?
4. checking throttle body for oil
I will say the idle is not perfect - I have not changed the map since the weekend and put it back to a previous stable map after some runs (but it had started doing this before the weekend)
no faults in VAGCOM, but I am wondering if there is anything I can try to log to see if there is any clues on initial cold start, I might check the manifold and downpipe bolts as I wonder whether it leaks for a few seconds when cold?
