Thanks Dave, totally agree on these points. They claim that during the period of standing on the drive whilst I was on holiday this resulted in corrosion or rust which in turn caused excessive heating of the rotors. I will be sticking to my not fit for purpose argument. BMW UK not helpful and have declined both warranty or goodwill repair.

My 840i is 18 months old with less than 8000 miles on the clock. After brake judder it seems all four rotors are warped but BMW will not honour the warranty as low mileage has contributed to rotor corrosion. Anyone else come across this one? Probably on principle this will end up in the small claims court.
