What am I supposed to be filling in that reservoir? Doesn’t look like the multi contour pump to me!!
What do you think? Should I continue pulling out the backing to see further? It’s not very cooperative.




Here’s the part under the foam. No idea what it is. I did notice it is low on some kind of fluid. What is this? Is the motor further to the front section but on the left side still? Removing the cover is brutal. It’s like everything’s connected.

Looked like the foam covered part was it. Until…

@konigstiger I’m a bit confused. What’s the part I uncovered from the foam that appears to have a low reservoir? Where’s the pump hidden?
We all really appreciate your help.

Part you’re questioning is convertible top pump, seat pump should be behind amp & top pump inside dampening enclosure.

Ok. I’ll fill the reservoir and then continue trying to get the rest of the backing off. Seems I can’t figure out the last few attachments that hold it on.

Just the back half that’s giving me trouble.

Wow! I had thought the left section was the only section that needed to be removed. Doesn’t make sense why so much needs to come out to get to the left rear of the trunk area. I’ll look at it again.

also, I removed (and reinstalled) the front drivers seat to review connections. All looked good except one. This looked like someone may have taped it once. Certainly not OEM tape :-) but if that’s the problem why the motor doesn’t even come on, then the seat may need to be disassembled to fix that Mickey job.

Assume you checked f60 (7.5A) @ rear SAM fuse panel in trunk before jumping into disassembly.

Where is the multi contour air pump?

My vin is WDD2074561F088200, is the pump located in the trunk or behind the seats?

I also see these broken wires in the attached photo. I wonder if they could be part of the pneumatic wiring harness.

I have zero activity when the switches are turned on either seat.

Pump Location

Have you found your pump yet?
I have a 2014 Cabriolet and it is on the left side in the trunk.
Not sure if coupe is the same, i have seen many variations and certainly different from 2013 and 2014.

Does anyone know if this is the same location for the 2016 E400 A207 cabriolet, lumbar pump?
