L322 Compatible parts

My L322 needs a caliper, it also has BMW stamped on it so I checked the price difference, one for the RR is £100 and one for an X5 is £66, will the one from the X5 fit straight on? if so what other parts on the RR come from the X5?

Thanks

The L322 is an X5 in a posh frock.......they are very similar and share a lot of common parts....the transfer box is different, the engine bottom half is different, the ECUs are the same but programmed to be either a Range Rover or a BMW.....Think the Gearbox is slightly different.......not sure if the BMW caliper is the same....part number checking is prudent.
