W210 E55 Multi Contour Seat / Vacuum Issue

Hey guys, having an issue and wanted to get a few opinions. I have had an issue where the multi-contour seats are deflating (both driver and passenger) about a minute after start up. Here is whats going on.

Turn key on and start car, both seats inflate and adjust accordingly. After a minute both seats deflate.

When this problem started they would deflate 30 minutes after the car was started. Now its about a minute or so.

Here is my question, had my indy look at it and could not find any leaks in the system. (He only checked the drivers seat because at this point I did not realize it was the passenger seat doing it as well).

Took it to the MB dealer and they said it was the pump going out. If I am correct the pump that controls vaccum to the seat also controls the door locks? He said they tested it and it is not giving out full pressures as it should. However I have never and still don't have issues with the locks.

What do you guys think? Should I replace it?

try pumping air into the seat control module manually to see if the bags inflate.
then if it does, does it leak? if it does, then I would guess that the control
module or seat lines (or bag) has a you've eliminated the PSE pump
from the system.

you can use one of those drug store rubber baby snot bulb thingies.

you can also continue...systematically...try to introduce air along different
junctions along the air line as anywhere there is a fitting is a natural weak spot
for failure.

yes, PSE pump handles air supply to the door locks and seats, trunk lock, rear
