It's been my experiance that a car makes noise after the key is inserted and turned. Take the key out and the noise will stop. Problem solved!

Seriously, if you have power brakes check the master cylinder assy for a vacuum leak thjere as well.

You couldn't identify the sound of a slipping belt? You should have followed my advice and burned the car.

I never had a chance to get under the hood when it was making the noise. If you get a gnome that sits in your engine bay and whistles at idle speeds every once and a while, would you know what it was?

Now I feel bad. C'mere and give me a hug, SW...I promise to goose ya.

BTW...You should remove the gnome from your engine bay too. Mythical creatures are notoriously bad for anything mechanical.

At low (engine) speed you have high vacumn and the noise would be more prominent.. when the motor is under load vacumn drops and the noise is less noticeable.

A vacumn gauge would tell you right away... failing that... start tracing hoses.

Lazs is correct. Also consider buying a German car next time.

German cars are very low on reliability these days (believe me I know I have a Mercedes).

If you want reliability and a good ride, pick something like a lexus. If you want a superb ride and don't mind spending a thousand bucks here and there with your car, pick a german vehicle.

I.e. you got to love the german car seriously, because she'll ask a helluva lot from the owner.

The last reliable mercedes was built in -93 when the W124 final facelift was introduced. From there on there have been corrosion problems (changed to eco-paint) and with newer models mucho electrical failures.

W140 S-series had a wiring harness made from biodegradable plastic -> engine heat destroyed the insulations and caused a premature $1200 fix. And this was just one example - later models are even worse.

Enviromentalism is the cause of all evil.

I've heard a few bad things about Mercs recently.

But I'm on my third VW Golf and about to buy a fourth. I have been delighted with all of them. The only troubles I've had with them are as follows:

1997 VR6 - ignition coil pack failed, so running on only 4 out of 6 cylinders. VW Emergency Assist engineer came at 8am the next day to fix it and was done before 10am.
2001 V6 4-Motion - window motor failed. Emergency Assist patched it up. Got it fixed that week.
2003 GT TDi - cooling fans acting up, blew the 40A fuse (on the hottest day of 2004 - LOL). Known fan fault - fans replaced, all OK.

All repairs under warranty. Nothing here that would put me off buying another. Total mileage on all 3 cars ~150,000.

Well I was more thinking Audi, BMW and Mercedes when speaking of 'german cars.'

WV as a part of VAG does suffer from many related problems. Mostly transmission failures, especially tiptronic gearboxes are prone to fail and cost $15k to replace.

As long as you have warranty it's nice - except when you get into a shop circle as has happened to many people. The vehicle keeps on malfunctioning due to CAN etc. hardware errors sending mechanics to expensive wild goose chases. People have had to return $60k+ vehicles to repairs every 2 weeks for durations starting from 1 day to a month.

Guarantee or not, that's not nice.

Rgr that Siaf.

I must admit, I do like the Mercs - but there isn't really one with a body style to suit my needs - except perhaps the C-class coupé. Momus has just posted that he gets 40mpg from his - I wonder if that's a petrol engine - bet it isn't the 3.2.

Tiptronic gears - I would have been tempted with that for the Golf, but it's not available on the 4-motion models - only the FWD models. Given the choice between 4WD and tiptronic, I'll go for 4WD.

My E320 gets 31mpg combined hwy/city with emphasis on hwy drive as long as the speed is under 90km/h (revs below 2000rpm).

Anything over 110km/h drops it to around 28mpg.
