Engine Hiss
Posted: Fri Feb 15, 2008 10:01 am
Hi all,
Not posted here for a while, mainly because my car has been running sweet! I've got a 2.1Td D8, P Reg with 180K miles on the clock.
Yesterday when I left work, I noticed a hiss coming from what appeared to be the dash, at first I thought it was radio static but then noticed the radio was off! It kicks in when the engine is cold at about 1500rpm and as the engine warms it starts only appearing at higher revs until after about a mile the noise is completely gone. Has anybody got any ideas as to what this could be coming from? I drove to work this morning hoping the hiss would be gone when I started up, but it is still there.
[edit] editing to say, I can't hear it with the bonnet up, the only time I can hear it is when im in the driver/passenger seat with the doors closed. It's an odd one!
Cheers,
Ian
