Hello. A few months ago we bought an E 500 estate, 2003 53 plate, privately. One problem niggles in an otherwise super car. When I fold the back of the rear seat down to use the load space, the front passenger seat powers forward automatically. It then refuses to move back again. This means anyone over 5ft 6in with legs cannot sit in the front passenger seat with the load space in use. Fold the back of the rear seat upright again and all the controls work normally again. An MB main agent felt it was normal and the MB UK helpline is at a loss what the problem is. The car is unusable for us and unless solved it will be back to a, cough, 5 series. Any ideas either for a cure or an electrical expert who can have a look at it?
