I have 2015 W222 S400L hybrid. The issue I am facing is that the driver chair keeps on inflating to 9, 1.


To clarify the issue I am facing. Whenever I start the car, the lumbar inflates to level shown in picture and I have to deflate/set it to 0,0 everytime I start the car. When I turn off the car and come back 10 minutes or later to start the car, the car runs with the seat lumber set at 9,1 as if this value is taken as default value.

I took it to a garage that did seat normalization using xentery and no use. I took to another garage that used launch diagnostic tool to do the same thing, no use. I tried everything from reseting the chair memory, saving new inflation level and no use.

Please advise me on this matter.
