i have a golf diesel on cold startup it does not fire straight away it stutters and starts with a puff of blue smoke, ive changed the glowplugs and tested them plus the injectors , checked the timing put a one way valve on the pump, changed the fuel filter, no difference, next im thinking of...
Can anyone tell me anything I need to know about this make and model of car? I test drove it and it ran fine, but I don't know what to look for. They are asking $4700.
