My son's R230 (2003) has just started exibiting many electrical problems at the same time, symptoms include:
central locking not working,
dash displays shows error with roof - visit workshop,
battery error - visit workshop
only some of the instument cluster displays are working

All these occurred at the same time, I'm hoping that maybe it's a low battery causing all the errors though after a 20 mile run they were still there.

Has anyone had these symptoms before?

I had this with mine, I was lucky that I dried it out and all ok
