I'm going to add to this post / follow rather than starting similar one

I think my clutch is bad or going bad as well - I have 1 1999 SLK230 with the 5 speed manual - new to me yesterday.

Super charger clutch seems to work - I had the car off the ground on the lift and you can see the clutch on the super charger go in and out based on drive line clutch in and out.

My questions are:

Some of what I've read is the clutch should also engage and disengage based on engine RPM - is this only on the automatic transmission models ? or on the manuals as well ? Mine is engaged it seems anytime the rear wheels are turning.

The clutch has got the distinctive rattle to it. - in reading this seems like a common problem.

So like FLBRAT23 I am looking for any incites on this.

Mechanically pretty capable - just a whole new animal

Thanks in advance

Mine started as a little rattle and has gotten worse, i'm still looking for info on how to just replace the clutch not the whole S/C so when i get this figured out i will let you know. I also got a few errors codes on my as well, is your check engine light on?

Error codes
P0170 - Fuel Trim Bank
P1236 - Fuel pump control out range
P0410 - Air System A

I"m going to clean my MAF sensor today as thats most likely related to P0170 if not then i'll have to replace it .

Lets keep in touch since we both have the same car

No error codes or check engine lights yet.

Sounds good - love the car for the now - 36 hours I've owned it ..

Hey I just wanted to let you know that the clutch as been discontinued by MB and they do not have anymore in their warehouses in the US or Germany. I called 4 different dealerships and was told the same thing by all of them. Its not available. I ended up having to order a used supercharger with the clutch attached in order to get a new clutch. will just have to replace the whole thing , might as well. Just an FYI

Finding the same thing - Would you be willing to share where you found the used unit - not having much luck on that either.

Did you consider a after market clutch?

How was the change out process ?

Thanks
