Problems with lumber support memory
im a newbie to this site and after my purchase of a 2015 SL400 2015 AMG Sport I am having trouble with the drivers lumber support memory.
Every time I turn the engine off the lumbar support reverts to a hard setting (7-7).
I have set the support to a softer setting say 0-3 and set the memory seat but it still reverts to 7-7 every time.
This doesn’t happen to the passenger seat which remains at the required setting each time.
Am I doing something wrong or do I have a fault?
Any advice would be very much appreciated.

Here are a few seat docs that describe the seat components and location. It may be possible to swap parts between seats to isolate the bad actor.
Good luck!
