Hi X5Dawg, I followed your lead, sought of and replaced stnd bulbs with LED's in my rear number plate and boot area (trunk) today. When I went to start the engine (lights off) the instrument cluster (dash) screen says "check number plate"....
with the wife looking on at the rear she commented that the LED's on the no. plate flash (pulstate regularly) when I started the engine (with lights off ???), they then settle down after a few secs & stopped flashing. After turning on the lights they emit an impressive steady bright white/blue light. This tells me that the no. plate lights will flash even during the day when starting the X (not good surely).
I appreciate that LED's draw a lot less than stnd bulbs and could possibly be sending a signal that the 'stnd globes' have blown. The new no. plate bulbs = 3 Watts, boot 0.7 Watts.
Did you had the same problem??? Like you I propose to change all interior bulbs with LED's, but NOT if this prob is going to continue!!!! Should I not be installing a resistor of some kind,.,.,.,.Please help....
