Good Afternoon, my name is \*\*\*\*\* \*\*\*\*\* ill be helping you, so sorry to hear about the issues here on the Audi. Have you noticed any hard starts or timing codes set recently?

No it started very normal like it should and no timing codesBut just sometimes when i started the car it usually revéd itself a little more than it should when starting a cold start but other that everything else normal

okay thank you, \*\*\*\*\* \*\*\*\*\* the case then you will likely be dealing with a drive belt/pulley issue. these Audi models were very notorious for timing issues however they almost always set codes when that happens. i would recommend you have a mechanical removing the serpentine belt and run the car for a few minutes that way to see if the noise goes away. if it does it will be pulley/tensioner/belt related which is what i suspect here.

I also have a question on code 17843 secondary air injection pump relay short circuit and p2257 air system control a circuit low! I have replaced the secondary air pump thinking it was that and no the code still came up and then replaced the relay and still came back on and I’m pretty the relay for that is by the motor right but yeah any idea why it might keep coming up

unfortunately since that is a separate question you will need to open a new question to have that addressed. its the sites rule not mine.

Hello. Is this related about the initial pulley question you had?
Customer

It’s actually about some codes and I think it might actually be the chains and stuff actually now but I wanna tell you what the codes are and see if you can help

17748p0349

P0349 is a timing related code however it’s not a mechanical issue. it’s an electrical related code with the camshaft position sensor so it would not cause the noise and would be an unrelated issue.

that would set if we had the P0349 code. we would need to figure out that cam sensor issue first and then go from there.

I was told it could be the timing chai and timing cam tensioner and maybe timing belt sense it does seem now to start pretty hard
Daniel Chaidez

the code you have is an electrical code for the cam sensor so no based on the codes you have now I do not suspect a mechanical timing issue like I mentioned.
Customer

if I take off the belt and it still rattles when I rev you think it will the chains
Daniel Chaidez

That does make it seem that it will be a timing issue yes. I would still recommend we figure out the electrical issue first and then look into a mechanical timing issue.
Customer

you recommend I replace the timing sensor first and see what happens from there

correct.

I actually erased the codes and the check engine light came back on but I didn’t have those codes anymore so I’ll just have to keep checking and see if it comes back on with those codes I mentioned

Okay sounds good.

I have 2005 Audi A6 4.2V8 and it’s making. Rattling noice when I rev the car but when it idles it makes no noice and I took it to a mechanic and they said it could be this one tensioner and pulley so I got the parts but I took it to another place just to make sure and they said it was the chains that they were loose so idk who to believe but would the symptoms of the chain be ? And also when i sprayed water where the pulleys are the noice went away for 10 seconds so I’m not sure if it’s that or it’s actually the chains
