My just aquired 2003 CL55 is having seat memory issues that the dealer could not find. I was just wondering if anyone has any advice. When I put seat back forward for rear passenger to get in or out, the seat does not return to the position it was in prior. I need to push seat memory button 1 to return it to original position. I have also turned off the option where the steering wheel and seat move up and back for ingress/egress since at times it didn't return to the original position either. I'm trying to identify where the problem is so I can instruct the dealer to look there.

Considered putting some Ginko in the tank but then I read studies show Ginko has no benefit to memory loss.

thank you
