Hi all. Newbie here.

Anyone had a situation where the car starts first turn of the key for weeks and then suddenly won't fire at all (cranking over perfectly but no firing). I leave the car alone for 2 or 3 hours and it starts up first time and works perfectly for another few weeks.

The car is K reg Audi 80 2.8 V6 Quattro but I assume the basic electronics are the same for all models of that era.

Before you say "seach the forums", I have and nobody seems to have come across this before.

Hope you can help before I take a hammer to it.
