One more question please The bulbs under the red covers in the front doors are not lighting at all (I have not touched them yet at all, they are factory default). I think they should, when I open the doors (I have KESSY), but they don't. I tried to switch Leaving Home / Coming home functions on/off, but same result: no light. I have no error message on the CAR menu. Is there a way to activate them? I looking for something like this.

Hi Guys, I'm kind of a newbie, having a Combi 1.6 diesel. I'm going to replace my interior bulbs to LED (front, rear ceiling & trunk). My question is that I have W5W T10 LEDs, but not "canbus error free" versions. Will the computer show an error message if I use "non error free" bulbs inside and in the boot? My next question is about replacing the outside side mirror lamps to LEDs (I can hardly see any light when I get out from the car). Is there an instruction how to do that? Thank you in advance for your help
