My '91 730i LKM was playing up so i swapped it with the one from my 88 535i before i sold it, little did i realise that the older module doesnt cause the high level brake to to light up.
I remember or at least i think i do the LKM-B line being something other than B
Was hoping someone with a high level light could see what their one says, would be much appreciated so i know what im looking for when visit the wreckers.
PS Ive attached a picture of the 88 one im currently using
Cheers
