Title says it all, but more detail: 2006 E55 with 97k miles. Noticed over the past couple months the lumbar has been inflating on its own. Per my Autel scanner, I have a leak in the lumbar. (Makes sense...air is slowly leaking out, then it hurts a certain threshold and the pump kicks in to refill it). Anyways, I've found a few articles/youtube vids on NON W211 seats, but even with those, Ive not found CLEAR direction on how to remove the bladder from the back with just the rear seat panel removed. I can see the bladder but cant tell how to actually remove it. Anyone done this yet?

no one has done this repair before, I take it?

Nope... but whats the code? https://www.pelicanparts.com/techart...eplacement.htm


I'd love to have dynamic seats but after seeing the complexity, I'm happy just running the pump when it leaks down

dont recall the specific code offhand, but my scanner pulled up just one code for the entire car when I scanned it and it stated something along the lines of "leak detected in drivers seat lumbar". That code matches the symptoms I have/described above. The pump works fine (for now) because its pumping air into the lumbar bladder. But it leaks out within about 10 mins to a point where the pump kicks back in, and refills the bladder.

Could as simple as a bad hose connection. Your going to have to dig in there and see what's happening. If you had a code, we could see what the star say's.

I'm in the same boat. I got confused and started posting on the other thread Looks like it's the hose, pump or bladder. I read where the bladders are known to leak at the sides. Supposedly they can be resealed with a heat gun. Personally I thought of a soldering iron or seal a meal Not sure what they go for new? Post the fix when you get it.
