I've taken my front bumper off today and refurb my headlamps.
What's these two electrical items in the n/s wheel arch lining , facing the ground?

I'm guessing one may be the temperature sensor. One is like a probe, the other is a flat disc.

One is outside temp sensor for dash display the other is a temp sensor for your heated washer nozzles.

Thank you.

I'm surprised the washer nozzles need their own sensor. I didn't know they were even heated!

Unfortunately the rubber tube that connects them isn't, so in cold weather mine still didn't work

Neither do mine! I'm now on BMW No.5 with the washer heaters and all have been filled with anti-freeze additive, but none has worked when there is a frost.
