Question
Hi, A4 99 Quattro, car starts normally when cold, tehn I drive it run like a charm, stop for 2/3 mins car starts fine, yet when I start the car after say 10 plus min's I have to roll it over about 5/7 secs to start, but yet it run s just fine when it starts...? someone mentioned my coils ? or have any suggestions  ? thanx scott

Answer
My 1996 cabrio does the same thing.  I do not know if it is a fuel pressure issue, but since it always starts I don't really worry about it.  Coils will not be the problem, because then you would consistently have issues.  Maybe a fuel accumulator or pressure sensor...  Let me know if you find anything.  Jan
