Morning all!

Have just had the long tone signifying parking sensor problem on my 2002 HSE TD6 (first problem in nearly 3 years!)

Have identified the rear driver's side sensor as being the only one not clicking. However have connected new sensor but long "fail" tone still present. Wires seem to be intact/ok.

1. Does the ECu need to be reset via autologic or similar diagnostic tool?
2. Should it not work with a straight swap?
3. How can I check the wire and see if current/signal etc coming out at the sensor end? (am clueless as an electrician - completely useless with something I can't see i.e. electricity!)

Happy Easter!

james, take one of the other sensors out and try it in the dodgy one...this should hopefully eliminate the wiring . ... - .- -.

+1, take a working sensor and plug it into the drivers side then if the fault moves you know your replacement sensor is no good! If the fault stays, you know its the wiring!

Should be a straight plug and play, no need to set up on computer if working...

This may be a stupid question but if one fails, does none of them work?  Once a Blue, Always a Blue

Although they don't all work as they should, the good ones should 'click'

Make sure some of them click, as recently I had all the front sensors go down and it turned out to be the ECU.
The front wasn't working, but the rear was fine.

I replaced the ECU and all was good.

This might help ?

Done it. It was the wiring loom. had to unravel it quite a way back to find the split. I had to take the rear bumper off to get to it though. THe really stupidly thin wire in the middle was torn. Simple splice and box junction inserted, original sensor back in and 100%!

anyone need a brand new BMW/unipart (same as my original) sensor? PM me.

THanks for all your help and answers.

PS the powerful videos are really good.
