Rear PDC Going Off

Hey all, my rear PDC is going off when I start up the car in the early morning. This has happened twice now. The first time the sensor was showing on the right, and it stopped when I wiped off the snow from the rear right sensor. Today first it was showing the right, then the left as well. Is this normal during winter or is it indicative of a bad install job of my M Sport rear bumper?

I get the same whenever there's snow/ice/significant salt buildup on any sensors.

Especially annoying when I come to a stop and the car starts beeping because it thinks I'm slowly driving into a wall

Ahh okay! As long as it's normal that's fine. I can live with it since it only lasts for 5 seconds while I reverse.

Yea but if you recently swapped out your bumper for an M rear bumper and the problem started after install then I would definitely suspect the installation as well. Could be just a coincidence or not. Any way good luck.

True enough but this is my first winter with this car, so I don't have anything to measure against.

This happens to me from time to time after washing my car the night before.

LOL or if you live on a island, lobby your government to have the island towed to warmer climates, just writing a letter to T. May
