Okay, I have researched this and I cannot find the correlation to the engine codes but I can tell what its doing. I got the car about 1.5 years ago with 60K in mileage..it was using oil but as I read, alot of them do. Within 6 months it was storing an engine code which turned out to be "turbo under boost" or something to that effect....I researched that and then replaced the turbo bypass valve and the it seemed like things were good...maybe the oil usage decreased some? Maybe some lag went away and some power came back.

Then within the last 6 months the oil usage went up and finally last week the car was running roughly at idle and the check engine light was on and then then ECS light came on. Oil is misting or splattering from the the exhaust.

I took the car in to a local shop and they reported the following codes:

5665
5671
4096
7455
4608
4000
7937

The only one I can find is 5671 = Boost pressure regulation: Control range not reached.

From the forums it looks like it could be the PCV valve or other issues.
Can anyone tell me what the codes are and what this might mean?

I appreciate it.

Jeff

 

I don't know who gave you these codes but they do not look correct. You need to get them read again. Audi OBD-II Trouble Codes
