Thread: L322 Wireless Rain Sensor

Your sensor doesn’t look complete.


See my posts starting at page 4 of this thread:

What year model is yours? On my 2003 model, there is a cable that plugs into the sensor.

My rain sensor didn’t work after my screen was replaced and diagnostics indicated it was faulty so I ordered a secondhand one from the UK.

While I was waiting for it to arrive, I noticed in the Faultmate software that there was a rain sensor recalibrate feature. I did that and it came good.

Now I have a spare sensor in the garage. I can lend it to you if you want to help diagnose the system.

Thanks Ron - she's a 2010 but I don't think that component has changed much.

Just confirms yet something else that's been cowboy'd *sigh*

I'll dig through your post for more details. Thanks again

Note that if the fuse is removed then the wipers become intermittent.

I think yours may have a Ford rain sensor, not the BMW one like mine.

Thanks Graeme, hadn't found that useful snippet of information previously.
