Rear parking sensors not working...

[NT_996]

Hi,

when engaging reverse, the parking guide shows red and does not detect any obstacles...

Sounds to me as though one of the sensors has failed.

How do I check this? Is it simply a case of buying a new sensor and swapping them out one at a time?

Any advice on where to buy a replacement sensor from, in the UK...Porsche OPC as good as anywhere??

Thanks, Neil.

Start by making sure they are clean and that none of the wires have been broken.

if any of them have small scratch/dent that would be the broken one. there tons of them on e-bay for about Euro 40 (go to ebay.de). they are the same sensors as touareg vw and tons of other cars (polo vw, audi etc). it is a dyi job, take bumper off, plug and unplug sensors.

Durametric will pinpoint which one is defective

What is the latest on this? I have the same problem but to be honest the fronts have once or twice flicked up all RED too but then quickly cleared?

moisture in the connections / sensors.      Have seen the same   :)

 

removal of the front or rear bumper and re-build the parking sensors, cleaning all the connections with electrical cleaner.    Then come around and do mine   :)
