I have had an odd problem with the driver's side seat memory function on a 16' S550. When I bought the car I noticed that the seat memory function only on the driver's side didn't work (passenger side worked fine). It would not save seat positions. Completely randomly a few months ago it started working. Worked flawlessly for a few months until I took it into the dealer for a Service A this past weekend. Got the car back today and the seat memory function doesn't work. Any ideas on if this is some easy fix or should I just take it back to the dealer?

Thank you!
