Q5Rob Posted July 12, 2021 Share Posted July 12, 2021 When my brake pad warning light came on I had my rear pads changed on my Q5 at my local garage. Unfortunately the light is still on despite putting on new sensors. Is there something I’m missing? Does Audi have to reset anything?

Envy Posted July 12, 2021 Share Posted July 12, 2021 The warning light is controlled through a sacrificial contact connected to the brake pads (normally on only one side of the car) If this is not replaced when the contact is exposed / broken then the warning will not go. They are normally a separate order item aside pads / disks 1 Quote Link to comment Share on other sites More sharing options...
Q5Rob Posted July 13, 2021 Author Share Posted July 13, 2021 Ok thanks for that. I will inform my garage 👍 Quote Link to comment Share on other sites More sharing options...
Envy Posted July 13, 2021 Share Posted July 13, 2021 Just in case they get a little excited with the pricing see link below - they should have checked this when changing out the pads. If the dash light is on then the sensor is done. https://www.eurocarparts.com/search/106440178?type=shopping&gclid=CjwKCAjw87SHBhBiEiwAukSeURuOF5D_f3rGSYyZVbcgMW-u5v76NwInXX3FaDeMtmAfH7PfCEn0PRoC-FUQAvD_BwE Quote Link to comment Share on other sites More sharing options...
Stevey Y Posted July 13, 2021 Share Posted July 13, 2021 Hi have you considered the possibility that the front pads may have not been far behind the rears wear wise. Steve Quote Link to comment Share on other sites More sharing options...

Andy Holt Posted October 10, 2022 Share Posted October 10, 2022 2018, Q5 (latest shape). Pad warning light can on 3 months ago. Had pads and discs checked, all ok. Decided to replace pads, discs and sensors. Light is still on and reset tool states “open circuit on both calipers and tyre pressures low on both rear Tyres. must be a connection problem but both calipers are working fine and Tyres ok? Help please! Quote Link to comment Share on other sites More sharing options...
Q5Rob Posted October 11, 2022 Author Share Posted October 11, 2022 My apologies I should’ve concluded what the problem was…. It was in fact a broken core (electrical wire) to the sensor. It didn’t need new sensors at all just like it didn’t need or get new brake disks as all major car dealer try to impose on unsuspecting customers.

Seek reputable independent professionals regarding dealership recommendations. They are probably lining their pockets with premature simple work Quote Link to comment Share on other sites More sharing options...
