I see. Truth is that the Mercedes system needs some fluency in navigating (that I am far from) and sometimes logic there is strange... on top - we are looking at digitized records and this kind of transfer can generate mistakes. Translations on top with the most famous one: washer = window. I recently came across "condenser" - I was looking for noise reduction capacitor, I almost ended up with AC condenser...
Alas, Mercedes emailed me today saying that the part was out of stock in their whole system. This is a frustration for me, as they do this often -- showing parts as in-stock when they're out-of-stock, at least over here through the dealer network.
I did remember one part I ordered through them that really didn't please me. The shift knob. After the engraver ruined my bakelite original when I tried having a 5th gear added, I ordered a new knob (for the time being) through Mercedes. It has since been replaced with a nice billet one from SNG Barratt intended for Jaguars with Getrag 265/6 swaps which is dimensionally the same. But this knob from Mercedes was not at all like the original -- light cheap plastic, and the pattern was not properly projected upon the round surface. That is, it was clearly designed on a flat surface, and overlain on the round surface, leading to lots of distortion around the edges. Basically what I'd expect from a cheap Chinese copy rather than something from the source.
Edit: oh, I ordered a new cable from Rhode Island Wire, since I can't find the "right" one anywhere. Really nice people.
