Lumbar Support Deflating on its own

bimmer_girl89 · 06-09-2020, 03:02 PM

Just wondering if someone here had experienced the same thing. I was searching other forum but I can't find a more recent post about side bolsters deflating.

I normally don't inflate the side bolsters to max very often but I don't remember them ever deflating on its own once they are adjusted. Yesterday I had mine fully inflated as I was using the heated seats to ease my back pain and I noticed that the left bolster do not hold its position. My drive home is about 30mins and in that span of time, I had to reinflate the bolster many times and have noticed that the side bolster keeps deflating.

Anyone had this issue before?

I feel like I do have to give it a shot every few weeks, but definitely not several times in 30 minutes.

Mine was a bad switch; fixed on warranty

Not on this car, but it happened with my 135i. There was a leak in the "balloon" that inflates. Dealer found it and replaced it. Never leaked again for the last 80k I owned it. If you're under warranty, should be covered.

Had same problem in my X3d and a 911s. Different causes. One had a bad pump valve, the other a leaky air bladder.
