Parking Sensor Fault - C7 RS6

[ShaneyB]

Hi all,

When I select reverse in my car I get a 5 second continuous beep which then stops. Both front and rear parking sensors don't work but the camera is fine.

I noticed a van with a trailer full of branches had reversed too close to me on a local high street so I'm wondering if any of the branches could have damaged one or more of the front sensors? There is no visible damage at all. Spoken to my local dealer who as usual wants to charge me £140.00 for an inspection after just spending £6k with them for lambda sensors and brakes among other things

Any thoughts/advice welcome.

Cheers
