Loud Engine Whine at Starting

Just as it says, I get a loud & sick sounding "waaah" sound at startup. Anyone else with a C55 have this? The dealer said it's normal.

When i actually "did" have my car, on a cold start it would do that, then quiet down in about 30-45 sec.

I would say you should ask the CLK55 owners if they have the same problem. That way you can tell if it's normal to the engine or if its some other component special to the car.

No, doesn't sound like a fan. More like a gear/pump whine when gears don't mesh correctly. And it is definitely louder when the engine is cold. It slowly gets quieter & is probably gone about 30 sec's after start. Just crossed over the 1000 mile barrier this weekend... now some fun starts!
