Can u add lumbar to 2015 ml350 passenger seat?
Does it require ecu programing?
Does the power plug for the bladder pump exist in all ml350?
Can the parts be added sepretly or do you need the whole seat swapped?
Is it just a air bladder, seat button and pump?
The strange thing is mb parts does not show any lumbar parts in the passenger seat diagram but the lumbar seat was an option when ordered from the factory.
I know there might be an aftermarket lumbar but would like it to be factory.
