Could be your coilpack. Mine did the same thing a few weeks ago.

It was built in 09/02. I thought the coilpack issue was fixed by then

Supposedly, but there are members in the forum who own 03 models and had to turn their cars in. Of course, there's the small stuff like checking your gas cover to make sure its tight and stuff like that, but the best way is to VAG it. If it is your cp, it'll say something about an error code and id the cylinder.

How can I find out if my coilpacks should have been recalled? No recall letter yet...

Default Mine goes on and off like a pair of binary *****'s underwear.

Happens to many A4s for no apparent reason. I just ignore it now.

Default Maybe it had something to do with the emissions system...

usually when coilpacks go, there are more tangible symptoms than a check engine light that disappears after a couple days
