Parking sensor fault

Post by rickyclean » Sat May 14, 2016 1:22 am

Hi all

Last weekend my 2007 X5 e70 started having parking sensor issues. When I fire up the car and place it in reverse a warning on the idrive saying parking sensor fail and the sensors don't work. What is doubly weird is it also says the parking camera is faulty though the camera is working on the screen. Any thoughts people?

Thanks in advance!

I can't comment on the associated camera message but I've had the PDC message failure come up twice now with a long period between.  About 3 years ago the message first appeared. Advice on various forums all suggested giving the sensors a thoroughly good clean.  That didn't work and an auto-electrician quickly found one of the sensors was faulty using Bosch diagnostic equipment. A non-BMW sensor wasn't available easily so he put a genuine part in. The part was about £90 and total cost about £140, including VAT. Diagnosis and fitting took about an hour.  No trouble until last winter when the message appeared again. Thorough cleaning right into the recesses got rid of salt deposits on the sensors,  and no trouble since.

The moral is - give all the sensors and camera a careful clean.  They may be linked in terms of sending a fault message.  If that doesn't work, then it's a trip to an auto electrician to fix it,  or a dealer which will no doubt cost more!

Hi Graeme

Sorry for not replying sooner and thank you for the advice. Good clean will happen at the weekend and will report back... Utterly baffling though...

Hello again all

So I gave the car a thorough clean before a trip up to Norfolk last week and this seemed to have solved the problem or so I thought. So on Thursday the parking sensors decide not to work at all and the original message of "Camera being flatly" (Though working fine) came up. Gave the car a thorough clean on Saturday and it is still not working. Can anyone recommend a good auto electrician in the Haywards Heath area?

Cheers

Have you tested any of the sensors, or swapped any out?
One of my sensors was on the fritz and gave me the same error message- swapped it out with an Ebay Cheapo (which works, but 70% of the time bleeps for no reason) and solved any of those problems.

Dead easy to swap out - about 2 minutes on the rear.
