After renewing the battery and restoring the keys, after 2 months my XF (x250 3.0 SC AWD) started throwing up a number of warnings:

• A battery warning message
• Eco stop inhibited message
• Wheel tyers pressure system fault, and
• Locked gas tank cover (it is not worning).

The workshop was sad that the rear BCM has Internal Error and needs to be renewed.

Has anyone else encountered a similar issue and found another solution than buying a new BCM?

They can go bad but an attempt should be made to reflash the BCM prior to replacing it. The shops have an obvious profit motive to suggest replacement without even trying or just pretending it can't be recovered. If you don't trust the place where you took it to do that, try somewhere else for a second opinion.
