@niedzial1983 @KrisKrk , So...the LED number plate bulbs and side lights I have ordered are going to throw this fault up, even though I bought ones that 'apparently' have the 'CANBUS' (?!) thing on them that is supposed to stop that?! What a pain in the tezzy. This is upsetting. And you have the same issue with whole aftermarket units as well @KrisKrk ? Apologies @Stricky2309 for clogging up your thread on this.... Cheers all. Keith.
