Location of the air pump of multi contour seats
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…
We all really appreciate your help.
Just the back half that’s giving me trouble.
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.

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.




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.
