So I've recently bought a 2.6 auto and it from factory had a orthopaedic drivers seat, when I bought it the seat didn't work as one it has a broken switch which I can't find the part number and cannot find it at all on the EPC so would like as much help on this as possible as I want to get this seat working again. If someone could give me a part number or a link to one that would be very helpful.

Done a quick jerry rigged test and all the bags in the seat work fine.

I also need the correct pump as it's had the wrong pump put in at some stage which I have determined to be this one A1248002848 via the EPC. Can any explain the difference between the two, I know it has an extra outlet for the seat vacuum and the extra pin in the plug but what does the extra pin do and does it have a one-way valve in the pump for the seat?
Hopefully this link will work:
Its for a W124 but as far as I know the parts were common.
Ebay de has the correct pump on quite often: you may be advised to look there.
I'm not sure that there is a one way valve in the pump for the seat. My seats "deflate" when the ignition is off. I'm not sure whether this is correct, but they've always do it.
Good luck,
