ex-quattro PETE

Only happens on cold start-up, and lasts about a second. Comes from under the hood. Sounds more plasticky rather than metallic.

I've heard some people mention belt tensioner? Is that it? Is it a warning sign that it's going bad and needs immediate attention?

cam belt tensioner. I still can't get a tech to actually hear it.

start it up and hear that noise.

it's going to only get worse and worse.

skabaru

it will eventually throw a DTC... and then, eventually, your car will stall on startup...

I have had it repalced twice, the current one is holding out much better... 25,000 so far...

are there any serious risks of damage to the engine when the tensioner fails?

kinda like a small chainsaw is in your engine bay...makes the noise when you turn your wheel from side to side, but goes away right when the car warms up a little?

My car JUST started this yesterday morning.

If it's the cam belt tensioner, how much is it to get replaced? DIY? I'm JUST out of warranty.

BTW, what does it do, besides create tension on the cam belt =P

you sound like you have power steering problems - are you low on PSF?

Chard

where's the resovoir, so I can check?

ex-quattro PETE

on the right, near the windshield washer reservoir, IIRC.
