Thanks for all the responses. I will look into the serpentine belt, tensioner, auxiliary belt, and PCV. JBC2562: precopster is correct, it is a turbo. precopster: The headlights run during the day automatically. My manual on page 34 says: "Models with daytime running lights: Low beam headlights...

I haven't noticed any roughness when driving. Are there particular symptoms I should look out for with respect to the auxiliary belt? I have never had the auxiliary belt replaced. I bought the car with 100k miles, so a previous owner might have had it replaced. I did have the timing belt replaced a ...

Another thing worth mentioning is that the sound was gone this morning.

The sound persisted throughout the evening yesterday, but t...

FCPGroton: I haven't checked the regular horn volume. I will have to do that. However, I had already called the dealer about ajusting the volume of the alarm and they said they couldn't do it. jimmy57: That's interesting. It seems like I have seen other Volvo's and their sirens have beeped on lock a...

When I arm the alarm system on my '04 V70 by locking it (with the fob), the horn beep is way too loud (as in, I have to make sure no one is standing in front of the car, because it will cause pain to ears). Does anyone know how to lower the volume, or just disable the horn chirp completely? I don't ...
