BCM

Hi all

I have been having some strange things going on with the car recently, like cornering lights not working, Lane assist thingy working then not and the alarm keeps going off. Have done a scan and amongst others came up with U0140 00 lost communication with BCM . The code is intermittent,  so I hope it's just a connection problem.

I haven't got a clue where this module is or what it looks like the Internet has dozens of different answers to the same question. So does anyone have definitive answer to where the bcm is on a 2010 xf 30 s deisel?

Thanks

Dale.
