Thank you very much.
BTW - I didn't know anything about the EPC referred to in that thread. Looks like you need to give them a credit card "just to verify the address" (don't know why) but it is supposed to be free for a year.

Before doing all of that, do the parts catalogs that they refer to have exploded diagrams so that it is actually a useful resource for working on the car other than justt getting MB parts numbers?
