Hi all.

Has anyone else experienced problems with R171 parking sensors having a brain-fart and turning off after lots of rain? I've cleaned the sensors down but they work fine when it's been dry. Someone said it could be water in the main alarm unit? Only seemd to do it when we've had quite a lot of rain (as we have this last week or so here in the UK!

Thanks all!

PS - I've trawled through historic posts and done a handful of searches but couldn't find this anywhere, so there's a discussion elsewhere and people know where it is, please let me know - thanks again.

I had many problems with the parking sensors on my old 350 And ended up replacing at least 4 of them. Not cheap as they need to be painted.
You really need a good indie with Star diagnostics.
hope you get it sorted.

To start, give them a good clean.
If you can see behind the bumper, it may just be a loose/rotten contact.

Anything getting on the sensor sends them nuts and electrical contacts need to be good.

@G0RSQ did some playing with his. He'll drop by.

Personally, if I had it, I'd disconnect.
More annoying than roof rattles.
If I'm in her 350 with PT, it gets offed as soon as I start the car.

I do ocassionally - it's only when it's been raining a lot though - seems like something dries out then they're back to normal again. I'll give em a good clean & check over.

Once it's stopped raining (ironically enough!)
