Check for oil in around the ht leads and the condition of the ht leads as well. Make sure you hae genuine Bosch plugs and not some crappy equivalents.

found out is some thing 2 do with air flow meter as when it happens if i disconect and re connect the plug its fine. i have had another problem its only done it once worred it will happen again was just hittin boost then it just lost every thing 4 bout a sec if that

Disconnect and go for a run and see if that is better running...sounds like MAF

when i disconnect it its the same then if i plug it on its fine its started doing it more often and some times when drivin i think it must be the pins in the plug

I've had this problem, so have many others, give the Maf plug and socket a really good clean with some contact cleaner, some of us have just tensioned the socket pins up a bit with a fine screwdriver but be careful, they are easily damaged.

cheers mate done that think it is the wiring as if i pull the wires 2 1 side it works but not if i move them gunna get a new plug and some proper connections from audi
