Rhys3292 Posted March 5, 2017 Share Posted March 5, 2017 Apologies if in wrong topic I have a 2004 Audi A3 2.0 Tdi dsg - my reversing sensors don't work. When I put it into reverse I hear a beep for about 1-2 seconds then nothing - what could be the problem?? Please bare in mind I don't have a mechanical mind so I don't know any mechanical words so please keep it simple if possible Quote Link to comment Share on other sites More sharing options...
Trevor Posted March 6, 2017 Share Posted March 6, 2017 Hi Rhys...welcome to the Forum I would start by placing the car in reverse with the ignition on (engine off). Ensure the handbrake is on fully and go to the back of the car. At this stage, the reverse lights should be on and if you place you ear very close to each reverse sensor, then you should hear a faint clicking noise if it is working correctly. No clicking = sensor has failed. Let us know how you get on with it Cheers Trevor 1 Quote Link to comment Share on other sites More sharing options...
Rhys3292 Posted March 10, 2017 Author Share Posted March 10, 2017 Sorry it's taken ages to reply - drive shaft went so had to replace that. But it's the two driver side ones that don't work. The passenger side made the noises. Where do I go from here? And costs? Quote Link to comment Share on other sites More sharing options...
Trevor Posted March 14, 2017 Share Posted March 14, 2017 There are some sensors here http://www.audiownersclub.com/parts-search-results/A3-S3/Vehicle_Parts_and_Accessories/131090/reverse As long as you can get your hand up behind the bumper then they are easy to replace Quote Link to comment Share on other sites More sharing options...
Moira Posted December 15, 2020 Share Posted December 15, 2020 Hi, I've just had a gear linkage kit replaced as I couldn't get the car in reverse (2008 A3). Just noticed yesterday when I put the car in reverse there's no beep sound and the rear sensors no longer work. Could this be connected as it's too coincidental that I had this gear linkage fitted and now the sensors don't work. Thanks Quote Link to comment Share on other sites More sharing options...
cliffcoggin Posted December 15, 2020 Share Posted December 15, 2020 As you said Moira. It's too much of a coincidence. Maybe the switch is damaged, maybe the wires have not been re-connected. Either way, take it back to whoever did the work and get him to fix it. Quote Link to comment Share on other sites More sharing options...
Moira Posted December 15, 2020 Share Posted December 15, 2020 Thanks cliffcoggin, I'm taking it back tomorrow. Don't want them to fob me off with some tale as to how it's not related to the work they've just done. Quote Link to comment Share on other sites More sharing options...

Updated: According to the mechanic, "a wire had come off the sensor near to the gear linkage." I checked everything for myself before leaving the garage. Reverse sensors and reverse lights now work. 1 Quote Link to comment Share on other sites More sharing options...

Chloe_shannon1 Posted February 27, 2023 Share Posted February 27, 2023 My Parking sensors on an 2015 Audi A3 tfsi are not working. It is saying “ parking aid unavailable at this time” and when I put my car into reverse I hear a long beep for 1-2 seconds but goes after. The text that comes up when I go into setting is “the selected system is currently not available” what can I do to fix this Quote Link to comment Share on other sites More sharing options...
Magnet Posted February 27, 2023 Share Posted February 27, 2023 Hello Chloe, Sounds typical of an issue with one of the in-bumper sensors - which one?? Diagnostics will identify which one for you. Some have said that you can tell by putting your ear to each one, but that didn’t work for me. Again, spaying WD40 might do the trick, but again that failed for me. Audi will charge you around £160 per sensor, but I bought a new replacement one off eBay for less than £16, and that one even had the Audi part number imprinted on it. Diagnostics will give you the correct part number. This is important since there are similar looking variants. Fitting usually entails removing the bumper, but you may get away with it if it’s a corner one. Some eBay sellers offer a painting service. perhaps you could let us know how you get on Chloe. Kind regards, Gareth. p.s. Could you please complete your profile. Quote Link to comment Share on other sites More sharing options...
