Hi Jason Just by a process of elimination to make sure the reversing switch is working all other bulbs in the real light cluster work other than the reversing light (i know the VCD printout says all the other bulbs have a intermittent fault but they have all worked since I had the car from November 2023) I dont like getting beaten hence why I'm determined to sort this fault out Many thanks again Jason

Hi Jason thanks for the info i think i will change the connector/plug after ive checked the switch (although im still not sure where to look for the switch) as i saw a YouTube video with a similar issue to mine the new plug seems to sort his issue out thx again Jason

Hi Jason i will check the connector as the bulb carrier is brand new i have no idea where the negative earth is unfortunately is it one of the wires that goes into the connector (plug) thanks Jason

Hi Cliff Yes I replaced the bulb and the bulb holder was a brand new genuine Audi part so unlikely to be rust/corrosion I’d have thought Do you know where I’d find the Earth for this Cliff Thx again

Hi Cliff and Gareth thanks for your replies My reversing sensors work fine If it’s not the switch then I guess it will be the wiring do you happen to know the colour of the wire that feeds the reversing light Thx again

Hi fellow Audi people Could some one point me in the direction of the reversing light switch location on an Audi A3 1.4 tfsi 3 door i think it may be at fault as I’ve changed the bulb carrier because the light unit had let in water so it was soaking wet amzingly all the bulbs worked except the reversing bulb (i have now resealed the light unit with Bison glue) all other bulbs work fine but when I select reverse a loud beeb and warning on the DIS comes up If someone has a part number for the switch that would be brilliant or any other idea what it may be thanks all
