Hey guys, just bought a 06' S60 with 94,500 miles yesterday and while driving it home I noticed a sound similiar to a belt that is tapping or maybe closer to a clicking sound. A few miles later the CEL light came on. I took it into autzone this morning but it didn't send any codes through the reader. I did fill up gas yesterday and this morning re-tightened the gas cap in case that was causing the CEL, but the sound is still there. Here is a video of the sound.

If you have any idea's on what it might be; I would really appreciate it. Thank you!!

SOLVED-
Need an oil change very badly.
Thanks everyone.

 

it almost sound like valve,either-way this noise CAN NOT be good,did you fill her up with premium Gas,if not try a good gas treatment,or tuneup in a bottle.

 

I did indeed use premium gas. I have no idea what it could be or really where it's coming from. It goes away during acceleration, or maybe I can only hear it when low RPMs but i'm definitely pretty worried..I contacted the seller and he had no previous knowledge of it, of course.. The oil is pretty dark, the next scheduled maintenance is in about 1,500 miles. I don't know if that would cause that noise though..Updated above, the car has 94,500 miles.

 

I,d change that Oil as soon as possible,don,t wait for maintenance,it is something that you can do yourself.
BTW,did you buy it from a private seller or a dealer?How much you paid for it,approximately?

 

Thanks guys, it was the oil. The car had been sitting for a while and the oil was low/needed a flush and fill. Runs SO much better now. Thanks again!!
P.S The car was $4,500. Seemed like a good deal at the time.

 

Good, had you mentioned that,I would say the OIL instantly,since I could hear the valve knocking.
