It would seem to me that the check valve issue would be even worse after the
car sits for a long time so that doesn't match your symptoms.

Leaky injector can be bad news.  Unfortunately, the cylinders usually don't
drain that fast at all....unless its a very small leak.  It can eventually
hydro-lock your cylinder and you will wonder why the car won't turn over...I
went through a 3 month long saga of what I thought was a leaky injector on a
'91 200 causing this problem.  Turned out it was the FPR that was leaking
through the vacuum port and draining into the cylinder causing the
hydro-lock.

Hi all,

My "beloved" S6 have developed another reason to keep my week-ends busy.
When I stop the car for 5 minutes, it takes a loooooong time for the engine
to start again, like 10 or 15 seconds on the starter (Count them, it's very
long when your starter is running and you hope the battery will hold). After
1 minute, it's not so bad, after 30 minutes too and no problem after 1 or 2
hours. 5 minutes is really the shit spot. I've also noticed that it's a bit
better when I hold the go pedal to the floor before starting. This made me
suspect a leaking injector that would flood the cylinder within 5 minutes,
then the cylinder drains in 30 minutes. But the engine should start, rough
but start, on the 4 remaining cylinders... except if I have 3 or 4 leaking
injectors.

So, I'm stuck scratching my head in an attempt not to replace half the
engine bay to discover that a 5 minutes 10$ repair would have been just
right.

Any idea?



Vincent.
