Rear parking sensors not working

[George Adair]

2011 3.0 TDI SE Sline Auto Saloon Quattro rear parking sensors not working, When Reverse is engaged approx 3 second beep then nothing, tried the WD40 method, and the screwdriver test touching each sensor, NOTHING! 🤔

Hello George,

Amazing what is talked about on You Tube! I think you have joined the band of those who have tried these methods - but like you - have failed. 
Apart from changing all the sensors, you will need to get it plugged in to find out which is the offender. You can then look on eBay and find an aftermarket one at a fraction of VAG’s price. 
Kind regards,

Gareth.
