Parking sensors have been playing up recently, beeping incessantly when switched on, not switching off straight away and generally behaving like a stroppy teenager..

Wouldn't you know it, jump in this morning to take it to the dealer to check out and they are working perfectly again..

Mine used to do that... it was dependant on how much moisture was in the air.. not enough didn't work.. too much didn't work either.. but after it had rained heavily they would work for a few days.. then normal service would be resumed  Yesterday I couldn't spell Engineer... Today I are one!

Mine used to play up in hot weather.
After replacing the BCM (for rear door locking & heavy steering problems, also in hot weather), the problem went away ...  It's "bébéchoon", ackcherly, with accents. 'Steve' to my chums.

Having worked faultlessy for a week the rear sensors played up last night........fortunately I was reversing very slowly when I hit the building....

Luckily no damage but I must sort out the useless reversing lights.....

Not impressed though when SWMBO says "Oh, you've hit the wall"......No Sherlock.....  2017 4.4 SDV8 Autobiography

Don't they have a camera as standard? Yesterday I couldn't spell Engineer... Today I are one!

Yep they do but when its dark the reversing lights are next to useless

I was also expecting the sensor beeping to change tone too.......that'll teach me.....  2017 4.4 SDV8 Autobiography

Never ever rely on the PDC to do any thing except malfunction ... at the worst possible moment

Road dirt can send them in to a fit.. so a camera is better, but as you say you also need the LED upgrade too or a volunteer with a box of matches  Yesterday I couldn't spell Engineer... Today I are one!

Went for a little trip down South last week, and whilst waiting on my driveway at home turned the sensors off, Can't think exactly why. Anyhow, got down South to the smallest, tightest multi storey in the world. Guess the rest. Lovely little vertical scuff on the the rear bumper.

^ I feel your pain, reminded me of when i did this

I just thought . Still, gives me a chance to try out auto restore. Yours is a lovely colour mate.

mmm auto restore a partner of autoglass I wouldn't give my cars to anyone involved with autoglass go a court case going though at the mo the muppets fitted wrong screen in a ex car of mine and totally up car when it rained and ruined interior and electrics

I see, something for me to think on, cheers.

conversely, to balance the argument I have had autoglass replace several screens and had no problem, certainly less than with other national fitting companies which have been foisted on me by insurers.

TBH, i would get it to a bodyshop and let them do it. It will be a better, proper, job and not as expensive as you may think.

The guys who did mine took off the bumper, removed the PDC, repainted the damage, then re lacquered the whole bumper and refitted. Whole job was £270. And you can not tell, at all, even if you try that they have been anywhere near it.  There is nothing that can't be fixed with a hammer😜😜
