My 2003 quattro has been running rough at idle for a few days, but it doesnt throw any codes out when i plug the reader.. any ideas??

 

Describe "rough" does it run rough 24/7 on idle or does it come and go? It could be a bad CAT and the check engine just hasn't showed up yet. But there could be many other things that can cause a rough idle.

 

first thing that popped into my mind was the coil packs.

 

it feels like its gunna die at idle but it doesnt die. it runs like that 24/7 and i just replaced all four coil packs like last week

 

There are some general maintenance items to check when the car is running "rough"

First, check the MAF. Unplug the connector when the car is off, and start the car. See if it runs better.

Then, I would do plugs and make sure you have the newest coilpacks. They end in "D" and have a shiny top to them

Next comes your primary 02 sensor. This is the main sensor in the Bosch ME.7 system

 

P0011 is the code that came up. Intake Cam Position Timing Over Advanced - Bank 1

 

I don't want to hijack this thread and would like to find the answer as well, but are the coil packs covered under a recall or included in a Technical Service Bulletin?

 

Timing belt done recently....?
