I have a really annoying issue with my Rear parking sensors on my 2000 530d Auto.
Once put into reverse, they give a long beep, then stop, no intermitant signal, therefore, they are not working.
I have been told by an Indy that had a look a quick look at them, that it is probaly a break in the wire somewhere, and would take some time to track it down, and I really don't want to spend £££'s on Labour, any ideas that I could check for myself...I have been told the actual sensors themselves are all good...just the wiring !!!
