Reverse input signal fault

[Ryanm218]

I have a fault where the reverse light and sensors do not work when reverse gear is selected.

When I monitor parking aid input signal on VCDS the state does not change when I select reverse.

The reverse lights and parking sensors do work when I try them on the output test on VCDS.

After looking at this I ordered a new reverse switch but this is not the fault, the old one was fine when I tested it but fitted the new one anyway.

I have checked the reversing light switch fuse 15 in fuse box SB, that's fine.

Any ideas much appreciated.

Thanks
Ryan

Resolved. Was a broken wire on the reverse sensor switch plug
