I would imagine the parts would be the same as SLK as the cabin filter certainly is, but not entirely sure. It might be worth giving these guys a call

Do you have a forum member nearby that you could meet to compare exactly what parts are missing? I'm gonn have to pull my motor out at some stage soon as I've got more leaves in there. If you haven't sorted it by then I'll get some pictures.

As UKKen said, I think the fitting of the bits will be pretty straight forward once you know what is missing. Is the cabin filter there??

Hope you get it sorted soon - not the time of year for no heat! I have my seat heater not working and that's bad enough!!
