Been and collected it this lunchtime after another test drive and I read the codes whilst out & about and thankfully zero issues
Will collect the 18" alloys & winter tyres ASAP and then sell the 403Ms off; they've just been refurbed but a) I don't like them that much, b) not a fan of black wheels at all and c) the RFTs are shite
Parts already been ordered (OEM velour mats and M Sport grilles via Cotswolds BMW) and a full oil & filter change kit etc
The parts list will continue to grow haha
