Pimmen

I have to chime in as well, have a 2010 superb with bolero unit, I have Bluetooth in it and it worked when I got it used several years ago, but at some point it just stopped working, and now I'm thinking about really getting it to work again. I have tried unplugging, I have checked fuses (I think I have managed to check everything that has to do with phone or Bluetooth) Is my next option to search for a replacement BT unit? I have found one locally here in sweden but it's very pricey for a used part, the ones that are cheaper on eBay etcetera look to be in very poor condition and older than my car is.

I hear you, but as I wrote, I have checked each and every "pin" in the outlet, and only the pins where the corresponding lights are working is giving me 12V when for example I brake or use the turn indicators, so I'm positive that the problem is there.

Don't know, it's factory and the year is 2010 if that is any help.

I have had problems with my trailer lights for some time and finally today I tried to find out where the problem is. And I have used my multimeter and found out that the problem must be somewhere in the wiring, the lights are working, the fuse is fine since some lights work. I only get a faultcode on the left side of the trailer, where do the wires go FROM where I plug in my trailer?
