Hi,

I've posted this on other forums, but haven't gotten too many replies. I have a 2004 S60R, 6 speed manual with about 125,000 km on it. A couple weeks ago, I started to notice a weird tapping noise coming from the front of the car while on the highway. It sounds almost like a hollow plastic noise. It's not always there either, it comes and goes at random. I brought it to a mechanic, but they could not duplicate the noise. They've taken a look under the car, brakes, suspension, etc. They don't see any obvious damage or wear on anything.

I've noticed that the tapping tends to get faster when I speed up, but only to a certain frequency, then stays the same no matter how much faster I go and will eventually go away as I drive. The noise also seems to get worse when I lift off the gas, but gets better if I press my clutch down. Turning doesn't seem to affect the noise at all. I don't feel any vibration other than from the terrible roads around here. No warning lights or anything.

That's all I can think of off the top of my head. Can anybody help me out here?

Thanks in advance.

had this before on another car.
have you checked the cars under tray/ wind deflector?
after a service once i forgot to put in 1 bolt and as the wind buffeted under the car it was making a tapping sound

I have a guess. I think your throwout bearing might be rattling a bit.Not really a big deal with hurting anything.
The thing that makes me think that is that it goes away when ya touch the clutch pedal. Try just touching the clutch pedal when is neutral and see if ya hear anything. Sometimes a very delicate adjustment on the pedal assembly can eradicate a little anoyance like that. I have not seen it on a Volvo, but I have seen this before, I hope we are on the same page here.
