My 2018 RRS L494 has 2 codes in BCM marked permanent, U201B-54 and U2300-54 are these something to be concerned with? No real symptoms , other than in winter your feet are always cold , no real heat directed at floor,Asked dealer twice and basically said working as designed, did software update each time.

You will get more help on the Range Rover Sport forum, this forum is for Range Rovers...  Pete
