e90 Seat Bolster/Lumbar Issue

Vt335iguy · 02-11-2019, 07:51 AM

Hi All,

First post, I am getting ready to attempt replacement of lumbar pad and side (width adjustment) bolsters along with valves and motor. i can't seem to find a definitive DIY for this procedure and am at a loss as to how/whether I need to remove seat back springs in order to get bolster bags in etc... Anyone have a clear how to for this procedure? (Most of what I could find were good guides on retrofits...)

Many thanks, Liam

There is a repair guide publish on line called newtis.com You can look up your car model and under the repairs section for it, find all the procedures for repairing the seats. I was just in there this weekend looking at the sport seats for my car. I saw the repair guides for the lumbar pad. You basically have to pull the top torso cover off.

If you can money-shift it, it's a manual transmission. "Yeah, but NO ONE puts an automatic trans shift knob on a manual transmission."
