Hiya all after just buying our galaxy I asume all the diesels have the extra heater under the nearside rear sill , I am pretty sure mine isnt working , Should I get the vag-com lead and software to diagnose the fault or just change the plug in it as this seems to be the common fault , but if I change the plug will i need the vag-com to reset it ???? if I do where is the socket that you plug the vag-com into???? Cheers guys
