Chris Hunt Posted February 19 Share Posted February 19 (edited) Hi guys - new here. SQ5 2017 model. Dashboard shows intermittently a fault message saying ACC Unavailable / Distance Warning Unavailable. This happens mostly when it's very cold or very wet. I have a crack on the left side sensor / radar "lens" dome. I believe this is because the little heating unit inside the dome has failed, and read this on google somewhere. I have had Audi diagnose the fault and they confirm a problem with the left side sensor. They have quoted me £2,300 for the replacement, and I believe this is wrong. I think they're trying to sell me the control unit as well as the sensor. Can anyone tell me what the components are here, and if I can get a sensor without having to pay the Earth? Thanks, Chris Edited February 19 by Chris Hunt Quote Link to comment Share on other sites More sharing options...
Steve Q Posted February 23 Share Posted February 23 I'd recommend you get a second opinion from an independent Audi specialist Quote Link to comment Share on other sites More sharing options...
