side mirror puddle lights not working on 03 Cayenne S

[rambourg]

I have been trying to resolve the side mirror puddle light issue for several weeks with no luck. I even ordered new lights and replaced the old ones with no luck. Everything else as far as the headlights, side lights, license plate lights works as they should when I lock or unlock the car so I am stuck. I have checked fuses, tested it at night so it is not a sensor issue, comfort settings are checked but I don't see any settings specific to mirtor lights though. I have read somewhere that the puddle lights have to be programmed to work via PIWIS at a dealership. If that is the case, I was wondering if the Durametric enthusiast or pro would work for that purpose...may be cheaper in the long run to do it myself and have a nice diagnostic tool out of the deal. I appreciate any advice/input.

Welcome to RennTech :welcome:

 

To my knowledge, the Durametric Pro system will not address this issue, you need the PIWIS.

Update - went to dealer yesterday for another issue and had them try to program the puddle lights. They said their system is not communicating with a module so they would need to diagnose further. Does anyone know what module the mirror puddle lights would be part of?  Thank you.

The mirror surround lights are controlled via the drivers and passengers door control units respectively.

Thank you very much.  I will dig into this over the weekend.
