My R1250RS has a nasty habit of throwing up spurious error messages on the TFT display, and they seem to be getting more common.

The most common one relates to a faulty number plate light - not too serious; nevertheless I've dismantled the rear end of the bike to access said bulb, checked the connections and operation, and all appears to be absolutely fine. However in the last couple of weeks I've received similar TFT screen warnings about the Emergency Call System and also the brake light; again, 'false alarms' as far as I'm aware.

The other thing I've come across is that plugging in an OBD reader today to reset the service intervals, I notice that it's full of error codes, some of which are English and others are either gobbledegook or literally just the codes. Again, where I can understand stuff, it seems to bear no resemblance to the reality of my bike.

Is this stuff normal? Should I be worried? Do I need to go see a BMW dealership?

NOT normal at all. I have had one code come up when there was a problem with the ABS self check first start of the day. Shutting it off and back on again and everything was good. Maybe an exorcism or witch doctor can help.

good call - check the battery terminals which would be the most common cause, especially if accessories have been fitted.

As the owner of an old German car, I've had to diagnose a number of electrical issues and I always try to eliminate whatever is common amongst the problems I'm seeing. So this points to the ground.
