r171: SLK R171 2005 UK car passenger door problem ; the central

Resolved Question:

SLK R171 2005 UK car passenger door problem ; the central locking does not respond to either the key or the buttons in the car, also the mirror on this door doesn't respond to the adjuster. The window and the indicator work fine, also when using the remote key, the drivers door requires the key to be near the infra red on the door but works fine at distance on the passenger side. any ideas ? thanks

Stan :

Hello,
If central locking and mirror do not work only on one door, this indicates failure or glitch of door control unit. It might be possible to reset the door control unit by pulling it's fuse out for few minutes.


Door control module fuses are nr. 27 and 28 (should be white fuses) in the instrument panel fusebox.


 

Stan :

Ifrared receiver on the driver's door seems to be failing, if it works on the other side.

Stan :

regards,
Stan


 

Customer:

I have tried that before and it didn't work

Stan :

In this case, performance of door control module has to be checked with Star Diagnosis. If it is not possible to actuate central locking and mirror with this diagnostic tool- the control module is bad and has to be replaced.

Customer:

If it needs replacing, can it be done without the need to reprogramme the control module to the car ?


 

Stan :

Door control unit will need to be coded after replacement.

Customer:

OK thanks, XXXXX XXXXX waiting for the door module I ordered to arrive (£250 !!!)
