As if by magic on its 4th Birthday the Drivers side door lock has packed up ! Slightly odd fault as it simply won,t open via the central locking system but will by inserting the emergancy key.
Rather frustraitingly you can still hear the "clunk" from within the door but the door wont unlock. It will though lock via the fob or as i drive off.
Found this How too in US section

Its very helpful but has added a little confusion as it lists a Part no 51217202143 ? I can,t find this in RealOem but keep coming up with Part No 51217202144
Done a search of Forum and looks like this is a reoccuring problem in the US but very little reported here in the UK
Has anybody else had a similar failure and can anyone else shed light on the Part No mystery ? I,m looking at rectifying the fault myself and any advice is much appreciated.
