Hi Roiz,
That's looks to be a form of 'trimmer' i.e. a variable tuning coil. You'll probably find that 2 of the 7 legs are holding the external 'can' to the PCB and if it is a coil then this will be soldered to 'chassis' to screen it from stray RF. Inside you should find that it has the outer coil and the red slotted part you can see at the top is a ferrite core that is able to be screwed up and down within the coil to adjust the inductance.
The 82R is unusual as coils are normally measured in 'Henry's' or in this case I would have thought micro Henry's. 82R would suggest that it is it's resistance i.e. 82 ohms but from the pic it looks like a coil and not a potentiometer.

This part is more of an electronic part than an electrical part.

Hope that this helps in some way.

Cheers,
Lofty.
 
This unit is Parking Reverse Sensor Unit .

Some how water came into the bagage and it make some shortes into this components that I marked at the picture.

I opened the 4 units ( that I makerd) and I dry them out and only one was not working perfect :( and all the others working fain ....


some one know about this unit and could help me replace the varible inductor marked as "82R" ???
 
looks like a call to RS or Maplin's. maybe CPC. it's deffo a coil.
 
Take the whole board into Maplins. The geeks aka sales assistants there are usually pretty good at answering this sort of question.
