Guys, should I live with this noise that the tech is telling me is normal? C'mon, cars are sposed to be quiet, not make any loud embarrasing chirp when ya take off from the motor compartment.

The tech insists its the belt to the clutch of the supercharger and there's nothing that can be done to fix it. He tells me that there's repair notes on the matter but no matter what they do, it will always come back. To be clear, if I'm cruising around also, after I come out of a coast and press on the gas again the car will chirp again putting it under load.

I think I'm going to take it to another MB dealership and see what they say. I'm just worried that they're going to try and screw me and say that its not warranty covered a month and a half after I get this car with 8 thousand miles on it.

What do you guys think? Does anyone else have this chirp?

You are not alone, and neither are we.......

I questioned the same thing, it seems to have started just a little while ago.
Since I have been paying a little more attention to the chirp, I have also noticed it on the two E 55's and an SL 55 that I come in routine contact with. The SL is fairly new, with only about 8,000 miles on it. I don't believe it's the drive belt, I think it might be a bypass valve shutting down when we apply power. It seems to happen in approximately the same point in every car I have noticed it on.

The only chirping noise I hear at take-off seems to come from the tires :)

My E55 had the SC belt chirp from 3000 miles plus. It was common for those cars and the S55 (blown) I've heard at a meet.

This is the first time I've heard the chirp problem on a blown 6, interesting...there's not much torque there compared to the blown 8's.

Oh this is terrible news. I'm glad you said what you did, cause now I don't feel so all alone and it gives some merrit to what the tech told me about it being common. BUT non the less, it shouldn't be happening. [:(]

Its like you got this beast on the street, so many people don't know what it is, you take them for a ride, you start off in this luxury car and CHIRP! You look at them and say, hehe, that's the supercharger clutch engaging telling you that is operating with boost. They look at you like... ya, tell me another one.

How 'MBerrasing!

normal i'm told, seems that way too

I was also concerned when it first started at 3k miles but reading this forum reassured me that it is a benign sc belt engagement noise (since other slk32's were expereiencing the same). my recomm: don't mess with it. Just document it with the dealer and think of it as a friend who reminds you when it's time to smile [:)]

This seems to be a pretty common problem on the SC'd V8's. There are a variety of fixes. If you go to the other board and do a search on SC Chirp you should find a good number of posts.

Thanks 430, I found something that sounds like it will help, I'll do a copy and paste in a new post for everyone to read. If you found something better brotha, please, feel free to load it up. [;)][:)]

You guys have been so much help so far. I can't believe that I've gone through what I've already gone through with just 10,000 miles.

I do have to say in defense of the car, its still an amazing car. So powerfull it can scare ya.

Just tell people

Just tell people it's a blow-off valve. [:D]

I tried to deal with it with my E55...but ultimately it was one of my annoyances with it.
