I would like to thank golfgti.co.uk firstly but these people particularly

For their help and advice regarding ""GTI cutting out, oil light flashes""
Which I found it to be relay number 30.
Been over a week now and no problems (apart from some tit trying to nick it) Smashed two windows and made a mess. They cut them self in the process so hopefully the old bill will catch up with them. (Or bleed to death)
