have you looked for the BMW 11 digit or 7 digit part number that should be somewhere on these parts? If you find them...you can go to the online parts database and look them up. What model & year BMW are these parts from?
But the parts do look like a foglight and the temp probe.
Here's a link to the temp probe (looks like the one from my E38)...see item #5 and #3: http://www.realoem.com/bmw/showparts...65&fg=05&hl=14
Can you see the resemblence of the item in the diagram (at link above) to the pic you posted (below)?
