Hello,
I'm a new member here and was wondering if anyone has had any similar issues to me and might be able to help?
My A4 3.2 began to sound really loud on start up about two weeks ago and started to feel quite sluggish to drive. The noise was originally at start up and then died out when it began to idle, however since then the emissions light has come on (flashing) and the noise has been joined by a lot of shaking/rattling and continues all the time. I have used an OBD reader and found the following codes:
A friend of mine said it sounds like it could be cam chain stretch so he ran a test using VCDS software. We looked at Group 093 which is the camshaft adjustment values and you can see in the image that bank 1 exhaust is 31.9KW compared to the rest which are no greater than 6KW. I read somewhere that this figure should not exceed 8, and over 12 would generally mean it is skipping a tooth.
Has anyone experienced any of these issues? or have any advice they can give me? Next step will be to take it to a garage and get them to run diagnostics to get a definitive diagnosis, and go from there. I know that if the cam chain needs replacing the cost will be astronomical so hoping it could be something else.
Thanks,
Craig
