The oem electric lumbar kit i retro fitted in my 130 is one of best mods ive done especially on long trips, i tend to just leave it with lower bag quite well inflated which gives much improved lower back support, on long journeys its nice to alter it slightly which helps stop back pain ive suffered without the lumbar on previous 1series, was a lucky find on ebay mine which was a complete kit for bth seats including all bags, pump, wiring and switches etc:D

1 Series Lumbar Support Retro Fit

Post by Flyfisher5 » Mon Dec 31, 2018 5:34 pm

Just found this thread whilst doing a search.
I just wanted to share the lumber mod I did for my f30 with comfort seats. I used air wedges from amazon instead of the one listed in the thread. £10.99 for two. I had to buy a metre length of 8mm silicon pipe as the provided pipe is only 10cm.

The air pumps pipes were secured with zip ties. I’ve left the lower pipe zip ties with long tags for easy identification.
I’ve used it for a few days and it seems very comfortable. It’s surprising how little air is required to make a difference which is why it’s much better than a foam support.
It’s a really easy mod that can make a difference to comfort on long journeys.

Another quick update to the lumbar mod. I ordered the same single cell support as everyone else on this thread and fixed that as the lower back support. I also used a plastic file as suggested by others to protect the lumbar pad.
Instead of wasting the the air wedges, I’ve used those as bolster supports so in-effect making my own sport seat from a comfort seat. See photos. ImageImageImage
