Pneumatic Seats issue

Hey guys,

Glad to be around. I`ve bought a 2008 S63 AMG not long ago, it has the option for dynamic and multicontour seats but I`m encountering one issue which I couldn`t find an answer for just by looking around.
My passenger seat and rear left seat only adjust one part of the side bolsters. I`ve seen people complaining going back to "0" , not holding pressure. Mine are fine, just the side bolsters are getting inflated on the right side of the backreast only. All the other functions work as intended.

LE : driver seat is completelly dead except lower cushion side bolsters.

valves seem to stick - bounce about in the chair vigorously - but likely need dealer diagnostics to force the bags to inflate - u can control and measure pressure in every individual bag

frankly less stress to forget over complex unreliable features were ever fitted - a dealer will help you with a remortgage if you ask for their incompetence to be of no help whatsoever... you could join the benzninja club for much less than they will invent for doing nothing at all

I agree with Botus. After spilling much blood and treasure trying to get my system to work, it's just not worth it. Learn from our mistakes. Even if you get it running properly, it won't be for long.
