Hello,
I'm hoping someone may have some insight on my issue.
2009 A4 went to dealer for shaking at idle, running rough, etc.

Diagnosis - Timing Chain stretched/Timing jumped
Replaced timing chain, 2 tensioners, 2 rails. Inspected cylinders - OK.

Payed the $1700 bill, drove about 10 miles away, CEL is back on. Rough idle again.

Plugged in scanner- 9 codes- PO300, PO301, PO302, PO303, PO304, PO506, P2187, C1555, P2279

Unfortunately, this is not my vehicle, and I have no idea what the codes were before the repair.

This is a friend's son's car. I have called and left a message for the dealership service department, but I was wondering if anyone has any helpful hints as to what may have happened.

Thanks in advance!

Jay

 

OK I talked to the service department. They had apparently discovered the rear main seal was leaking/sucking air AFTER the $1700 timing chain replacement.

They claim that the codes I listed previously are a result of the leaky seal.

Is this possible?

It sucks because this 18 year old kid just spent a ton of money getting it fixed (or thought he was) and basically is back in the same spot.

The rear main will probably cost more than the timing chain I'm sure.

Thanks again!

Sorry but I don't buy it. A leaking rear main seal will leak oil out and not suck air in. Also if it did it wouldn't affect the running of the engine. They screwed something up and don't want to own up to it. Get in touch and arrange a meeting with the service manager and the GM of the dealership. You may also want to contact Audi of America. and have a rep available. All of the codes are ignition or timing related.
