Really sorry to read about your loss Tone. I'd be gutted, but thankfully your family are safe and your insurance will cover it. It's just the time involved with getting a replacement! Black GTI here as well...
As i'm recovering from a spinal op, my car is stuck on my drive with a cover over it, and reading this has made me very concerned. On my old Golf's, whenever I parked up in a dodgy area, or left them for any length of time, I used to pull the Coil lead off and take the fuel pump relay out the fusebox and take them with me in my pocket. I think I'll get my mate round to do the same on the mk6. Anyone know what relay it might be in the fusebox of the mk6?
