I have a 545i and I'm just wondering about my PDC malfunctions. Last month I was getting error messages saying PDC MALFUN. I don't get them anymore but that little triangle with the ! mark in it has been pretty much constant in my console. The odd time it won't be there but for the most part it is. Any advice? Thanks

It could be a faulty sensor or some other issue with the park distance control, is the warranty still in effect? Has the vehicle ever been involved in an accident? Has a short test been performed at the dealer?

Hi, warranty ended like 2 months ago. No accidents. Are those sensors easy to get at? Is it something u can clean? I wonder if it's expensive to repair.

Also, once in a blue moon when I start the car, a symbol with a P comes up, then it goes away in a minute or so. What's that?

Thanks again.

Goodwill might still apply if you can show the car has been kept up at the dealer. The symbol with a "P" should be explained in the owners manual.
