Thought id post a pic of it as well does anyone know if you can buy the dark grey cloth that covers the spare wheel cover and if so where would i buy some many thx again

Hello all im in the process of making adjustments to the boot of my 3 door A3 to accept a full size spare wheel it’s been quite a challenge but im nearly there just have a quick question about the screw down clamp that used to hold the space saver wheel how is the fixed part of the clamp assembly attached to the floor of the boot I cant see how it’s attached as i want to remove it and get a clamp to secure the full size spare wheel any help much appreciated

I’m a little confused as to there being no fuses in the engine compartment fuse box that you told me to check

Hi Jason I’m pretty sure this is the reversing switch all looks good inside no noticeable damage or anything once id removed the plug Im at a complete loss now i dont have an multimeter unfortunately

Hi Jason ive checked fuse F4 which is all good drivers side opened the fuse box in the engine there is no fuse in F5 or F7 (see pic) it looks like i have the 30 fuse version in the engine compartment i also checked the wiring in the black gator on the boot there appears to be no damage to any of the wires within the gator cheers Jason

Hi Jason Ill have a look tomorrow thanks for the info

Doesn’t look like the pic attached so I’ll try again

Hi All while searching for a fuse i popped off the plastic trim on the passenger side (same trim that covers the fuse box on Drivers side) and came across a plug which is unplugged i have attached a pic of it anyone got any ideas what it is and what it does?

Hi Jason Well I've looked for the fuse for the reversing light switch as per your message “Tech bits .. the central controller is responsible for reverse lights code 09-Cent-Elect .. but that's a whole new chapter CHECK F4 FUSE which is a 5Amp fuse in passenger side CHECK the wires in the plug terminal on the Reversing Switch” im really confused now as there is no fuse box on the passenger side (i removed the plastic trim to look) its on the drivers side i cant find any fuse that covers the reversing light anywhere including the fuse box inside of the engine compartment i will go ahead and change the plug once the weather improves again thanks for your help Jason

Hi Gareth Thanks for your info on checking the wires ill do that when it finally stops raining! Dave

Hi Jason Engine is 1.4 TFSI manual six speed

Hi Cliff Thanks so much for your help

Hi Jason With my car being a 3 door A3 there is only one reversing light on the passenger side and 1 fog light on the rear drivers side the fog light works its only the reversing light that doesn’t work i will check the fuse you suggest I'm not sure where i got that info about the fuse sharing with a/c i must have read it some where i was only going to remove the reversing switch to check the wiring and see if it was working thanks again Jason

Hi Jason First of all i really appreciate your help on this In answer to your question i have checked the fuse same fuse controls the a/c and something else so i know thats fine i will try the battery earth cleaning/ spraying i have soldered stuff before but prefer to leave it as a last resort but from what you've said changing the plug is the way to solve this once and for all This isn't going to beat me smiles

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 Guys i now have a VCD printout of the error : 7 Faults Found: 01134 - Alarm Horn (H12) 000 - - Freeze Frame: Fault Status: 01100000 Fault Priority: 4 Fault Frequency: 3 Reset counter: 95 Mileage: 168728 km Time Indication: 0 Date: 2023.11.27 Time: 12:00:37 Freeze Frame: Term 15 Off Voltage: 12.15 V OFF ON Term 50 Off OFF OFF 01518 - Bulb for Back-Up Lights; Left (M16) 010 - Open or Short to Plus - Intermittent Freeze Frame: Fault Status: 00101010 Fault Priority: 2 Fault Frequency: 159 Reset counter: 137 Mileage: 168799 km Time Indication: 0 Date: 2023.12.12 Time: 08:31:17 Freeze Frame: Term 15 On Voltage: 14.75 V ON ON Term 50 On OFF ON 00987 - Lamp for Brake Light; Left (M9) 010 - Open or Short to Plus - Intermittent Freeze Frame: Fault Status: 00101010 Fault Priority: 1 Fault Frequency: 2 Reset counter: 121 Mileage: 168800 km Time Indication: 0 Date: 2023.12.12 Time: 11:03:10 Freeze Frame: Term 15 On Voltage: 14.85 V ON ON Term 50 On OFF ON 01501 - Bulb for Blinkers; Rear Left (M6) 010 - Open or Short to Plus - Intermittent Freeze Frame: Fault Status: 00101010 Fault Priority: 2 Fault Frequency: 2 Reset counter: 121 Mileage: 168801 km Time Indication: 0 Date: 2023.12.12 Time: 11:05:26 Freeze Frame: Term 15 On Voltage: 14.95 V ON ON Term 50 On OFF OFF 00532 - Supply Voltage B+ 001 - Upper Limit Exceeded - Intermittent Freeze Frame: Fault Status: 00100001 Fault Priority: 4 Fault Frequency: 1 Reset counter: 121 Mileage: 168813 km Time Indication: 0 Date: 2023.12.13 Time: 11:17:26 Freeze Frame: Term 15 On Voltage: 15.50 V ON ON Term 50 On OFF OFF 01134 - Alarm Horn (H12) 004 - No Signal/Communication - Intermittent Freeze Frame: Fault Status: 00100100 Fault Priority: 4 Fault Frequency: 4 Reset counter: 130 Mileage: 168995 km Time Indication: 0 Date: 2024.01.18 Time: 09:07:15 Freeze Frame: Term 15 Off Voltage: 11.25 V OFF ON Term 50 Off OFF OFF 00897 - Windshield Washer Pump (V5) 012 - Electrical Fault in Circuit - Intermittent Freeze Frame: Fault Status: 00101100 Fault Priority: 3 Fault Frequency: 1 Reset counter: 131 Mileage: 169002 km Time Indication: 0 Date: 2024.01.18 Time: 09:46:36 Freeze Frame: Term 15 On Voltage: 14.75 V ON ON Term 50 On OFF OFF weird its showing errors in all the bulbs as only the reverse light doesnt work also the washer pump works perfectly the alarm I know isn’t working hope this helps thx guys

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
