Reviving my multi-contour seats

All I can tell you is what I did. Granted I have multi-contour only. But none of my buttons worked on either seat, suggesting a more systemic issue. First step was to locate the pump and determine if it runs during a brief period after the ignition is turned on (I don't think you need to start the car as my seats now work in what I call accessory mode or I guess position 1/one press of KG).
Anyway mine did not run. So, my step 1 was to get a pump that did run and go from there. After one DOA eBay pump I found one that works and is still working. I simply swapped in the used pump and my buttons all work now. Except I determined that I have leaky back bolster bladders on, I think, both seats, but the thigh and lumbar seem to hold air. That's probably as far as I'll go unless I feel like I have a broken line under a seat somewhere (pretty easy fix vs fishing the bladder out).

Has anyone done that for the E class models? Is the procedure the same or very similar to the S class bladder replacement video shown on another thread?

^^^^ This is accurate. I've done dozens of bladder repalcements. They are vinyl and on a 10+ year car with people sitting on them, they tend to crack/fail.
