The locks do not lock or unlock
Expert:  marcpod replied 7 years ago.

Ok you need to check this relay in the right side of the trunk. how you test a relay is by putting power and ground on side and see if there is power going out the other side. I am sending this in a jpeg if you need anything else just let me know.

1Connect quiescent current retention unit
2Disconnect ground lead from battery
3Remove paneling in trunk
NOTE: Right side paneling.
4Unscrew screws (1) and remove keyless Go control module (N69/5)
5Unlock electrical connectors (2) on Keyless Go control module (N69/5) and remove
6Install in opposite order.

Hello,

 

What is your recommendation to fix the door locks and trunk issue??

Expert:  marcpod replied 7 years ago.
My recomendation is taking it to a auto body shop that works on foreign cars. The labor rates are alot less expensive than going to a mercedes dealer Because it is an older vehicle most collision centers have the capabilty of pulling the code. Are there any light codes on. They can simplify it and because it is not considereda mechanical labor your going to save atleast 50%. if you need anything else jkust let me know ok. But according to the systems i have it does shoe the module back there.

OK, thanks for your help, I'll take it to shop.

 

Take Care
