The weird thing is there's only ONE idle control valve, so why 'bank 1'? It could be a bad plug or coil, more than the idle valve IMO. As far as I remember, when idle control valve goes bad, there's no specific code. THAT's why it took so long for dealers and BMW to figure out what the heck was wrong when it started going bad. Do you have an erratic idle when cold, or any other typical symptoms? Plus you always get a litany of warnings when it goes bad. Please keep us posted on what dealer does, and good luck.
