Lumbar Adjustment On 2019 SL...
On my ‘2008 and 2017 the lumbar seat adjustments were very obvious. Moving them with the control knob felt like a rolling pin being moved inside the seat. On my ‘2019 all seat options on both seats work but I cannot feel the lumbar move. I have looked under both seats and all connections are secure. Is their a fuse just for the lumbar adjustment?

Does the lumbar display indicate increasing and decreasing numbers as you make the adjustment?
Fuse allocation for my 2019 450 is:
“Seat adjustment, front”, Fuse 40, 43,116, 126; and
“Seats, front incl. Heating and ventilation”, Fuse 40, 43, 63, 64, 116, and 126.
These are the only seat related fuses in my fuse chart. No specific fuse was indicated for “Lumbar”.
Btw. I can feel the lumbar operating.

Yes, The indicator on the screen works fine and does show the change of numbers in the lumbar setting mode. Currently looking for my code reader I stored away somewhere. Someone on another MB forum was having other seat problems, found a code, erased it and his seats work perfectly now. It is worth a try.....
