RoyC Posted June 25, 2022 Share Posted June 25, 2022 I have replaced my H4 fog light bulbs with white LEDs, and of course I get an error on the dash. Has any one successfully done this with no errors ? Please, I'm useless at maths Quote Link to comment Share on other sites More sharing options...

Hi Roy they should be fine as long as you have the decoder wires as well these are basically Canbus wires to fool the lighting control module into thinking they are standard bulbs, so as long as you either buy what you have or Canbus error free bulbs all will be well, its got nothing to do with maths.

Last weekend my son borrowed the firms diagnostic thingy, he reset my SRI, (that Audi said they couldn't reset after doing a service) and went through every thing else. I realized that the lights out warning for the fog lights was no longer coming on. Just to satisfy myself that it was still working, I disconnected the left foglight and to my delight the left fog light warning came on. BRILIANT. I now have two sets of LEDs and resistor cables that are not required. Quote Link to comment Share on other sites More sharing options...

I just went on a run to my sons house (8 miles) there. He said that he did a dash reset. When I started up to come home the bulb out lights came back on.
