When I blip to unlock my four door Golf, the rear near side door will not unlock , (it does open and close manually) my dealer tells me that it will cost around £220.00 to repair. I am reasonably mechanical...is it a job for an amateur !! and can anyone tell me what parts I will need, or in fact any tricks to do the job. Also I am about to do an oil change, is their an alternative to 'specific oil only for my diesel Golf' '... 'only avaialble from the Main dealer' !! Thank you in advance tdilew
