Hi there, just bought a 1.9TDI Elegance estate for a (very) cheap runabout, picking it up next weekend,  the passenger door wont open, car comes with a central locking switch in a box, is this a big job to fit, any pointers would be much appreciated, thanks dave

If the door won't open at all then you may have to cut apart the door card to get at the system - this is not an easy job :(
