Dynamic seats in my E500




Yes I have have had a read of numerous threads, but think I have stumbled upon a unique problem.
In my 2003 E500, the driver seat is fine, the dynamic function works well, with cornering etc, the pulse/massage does as well.
However, with the passenger seat I have the pulse/massage function working perfectly, but the dynamic function doesn’t work.
I would assume, that as the pulse/massage function works perfectly, there won’t be any air leaks/air bladder problems.
What can stop the actual dynamic function from working though?
Can anyone assist me at all as to what the problem might be, apart from a Star diagnosis at the dealer.
Cheers,
Graeme
