Bring your own parts car owners tend to be homeless in the sense they don't have a regular garage and wander from shop to shop complaining about how the last shop ripped them off. Their cars tend to be real junkers that they expect to run forever and not pay for repairs.

The only time I installed customer parts was pre internet days when very good customers showed up with a Fiat or something obscure. On their more common cars, I provided the parts.

Either fix it your self or let the shop provide parts. Also, be sure the shop regrinds the flywheel, some don't do this as it ties up the bay while the FW is at the machine shop. Having a flat flywheel surface is critical to long clutch life and crisp clutch release.

But when I was flushing the hydraulics it was obvious the clutch had never been bled, the bleed valve and port were were plugged and what did come out was really dirty. That clutch slave failed at roughly the same age. I'm thinking, since Mercedes sticks are so rare dealers don't think to bleed the clutch. I'm going to bounce that theory off the dealer and see if it gets me anywhere.

And I got my 2000 posts!

Don't focus on the slave when you don't know what is really going on. The only failure mode of a concentric slave is external leakage. Make sure the clutch system is full of fluid and go from there.

Does the car move if you start it in gear? If not, the clutch pressure plate diagram spring is broken.

Calling the dealer for DIY advice is a bad idea. They are busy with paying customers and don't want to take liability when a DIY guy damages their car.
