My left number plate light hasn't been working for the last 4 weeks. I've had no fault light on dash. Decided whilst I was going to change the bulb I may as well change them to Canbus friendly LED bulbs. I removed left holder - no signs of water ingress/rust and connections look fine as did the bulb filament - swapped in LED bulb and refitted - no light and no fault on dash I then removed right side to try one of the LED bulbs in that side - no signs of water ingress/rust and connections look fine - swapped in LED bulb and refitted - no light and now getting a number plate light fault on dash. Tried refitting original bulb to right side and lock/unlock to reset fault light but fault light is still on and right light not working either now It's a 2004 2.0tdi if that makes any difference and I read through all of the LED bulb threads before going for the 3 led Canbus Festoon bulbs from ebay that a few other members have tried with no problems. I'v also had the bootlid trim off today to try to sort out the rear washer jet but it would appear that the rear washer tube has disconnected at the front reservoir tank. No water head been leaking behind trim. I'll get this sorted along when the aircon condensor gets done next month Any advice on the number plate light is most welcome and any other methods for clearing faults other than diagnostic (can't believe it would have to be hooked up to clear a bulb fault!!!) connection. ? Next repair - replace bulb holders??
