Parking sensors
Discussion
Hi peeps.
My parking sensors were intermittently going off now they have stopped working completely.
Im booked in the garage in a few weeks but tbh i hate taking my car to the garage if i can help it.
Ive seen online how wd40 is used and can in most cases fix the problem.
Problem is if i do that and it doesent work do you think i scupper my chances of getting the garage to do anything under warranty? I mean sensors are exposed to the elements which could be anything.
Also i dont really understand how wd40 helps but most people say it does, my sensors are the type where they are colour coded to match the paint with a black rubber seal around them.
Also does wd40 do anything to car paint?

Even if wd40 did anything which I doubt it’s definitely not going to do anything sprayed onto the outside painted face of a sensor.
The wd40 thing would be if water had got into the connector at the back.
Theres a youtube video where the guy sprays it on the sensors and it ends up working and tons of people agreeing, i also dont see how its possible unless it penetrates the rubber seal. The wd40 thing would be if water had got into the connector at the back.
It does seem to coinside with jet washing the car but i cant/dont know how to get to all 8 of the sensors.
I did try wd40 about 10 years ago on bmw e39 sensors (not under warranty) . It did seem to work temporarily for a couple of weeks. I guess it displaced some moisture. Ultimately it needed a new sensor though as the seal had obviously gone.
If yours is under warranty though seems a no brainer just to get them to sort it out, as sensors aren't cheap including the awkward labour involved in getting at some of them.

WD40 won’t damage your paintwork.
WD40 is a water dispersant and so if your problem is caused by water ingress then there is a chance that a squirt of WD40 will fix the issue, although maybe only temporarily as water will work back in over time.
If it is under warranty then I would let the garage sort it out. If you fix it temporarily using WD40 then when it comes back your warranty may have expired.

I have the same problem (Citroen C5 2014).
It's likely that only one sensor is faulty, so worthwhile working that out rather than replacing them all, but how to tell?
I was told that a sensor makes a high-pitched whine or buzzing noise when on, and not if it's faulty. Can anyone confirm this?
At my age, high-tone deafness means that probably I can't hear it anyway.
And, as the system only turns on in reverse and not at all when the engine is off, I need to recruit a suitably young assistant to listen, while I sit with my foot on the clutch!
Thanks,
John
