Read what I posted last. I think it would probably be the cam sensors. Good luck.

 

Since your here and im lazy where is thecam sensor? Is it easily accessible?

 

Yes it is easily accessible; keep in mind this was on his late model A6. It depends on if you have a 1.8 or a 2.8. His engine has an intake and exhaust cam position sensor for both banks totaling four in all, but he had the VAG program to tell him which one was mis-reading. I believe the sensor isn't outrageously priced, somewhere around $30 and it takes about 2 seconds to install. From what I can tell you basically follow the head covers towards the back of the car. When you get to the end look on a vertical face for two ports. I included a picture of his engine and about where to find them. Hope this helps.

Here's a link I found on ebay. The listing states it will fit most b5's, so something similar to this is what you should be looking for.

That one in the ebay link looks a little different than mine. I really dont think its the cam sensor, I checked and everything looks fine. Ive been searching and it seems like people with bad cam sensors can't even start their cars. ill keep it in mind though thanks for the advice.

 

you'd also probly have a CEL if it was the cam sensor. maybe its the 006? check the o-rings inside. i never had to change them and pretty sure badluckaudi (who owned it before me) didn't either. it would be a really cheap and quick fix too, so its worth at least checkin.

 

^^Alright Ill check that when I get home.

 

Sounds like your O2 sensor to me.

 

you should refrase that.. do not use autolite COPPER..we all know copper will fowl easy anyway, but i have always use autolite iridium on a .025 gap and have had great luck..but i have burnt a couple copper before, so i dont use those anymore

 

no, all autolites suck. they do well in domestic NA engines, but thats it. and you shouldn't be running iridium plugs anyway
