I wonder if VW, when they hear of recurring problems, try to fix them immediately, ie if they hear of this lock problem, might they fix it on the assembly line so that mine, apparently being built now, will have had the problem removed...??
I know it's easy to say but it just shouldn't happen - locks should work - German cars do not top the car reliabilty tables in response to surveys - Hondas and Mazdas etc seem always to finish at the top - that's my experience of Japanese and German cars....I hope the Golf won't let me down - that said, my wife had a Golf Tdi 100 bhp years ago and we both loved it.
