Voltage surges

Ok there are more earth points underneath the battery tray and another one which is visible when you are underneath the car looking up past the power steering control unit - this one bolts directly to the chassis. You'll find another one on the other side of the engine bay near the intercooler hose. Undo them, clean them up with a wire brush and put electrical grease on the before tightening them up again.

To more than likely solve the power steering issue, clean up the connectors that attach to it - both are accessible from underneath the car. You'll need some electrical spray/cleaner - let it dry - and then reconnect them. That 100% solved a similar problem on my car.

I had a similar problem on my Mk2, there was a HEX bolt on the steering column that came loose and it was part of the ground for the dash. So this very much seems to be a grounding issue. You might be able to isolate it by using a continuity test from chassis and testing the column, and chassis areas that are affected.

Good luck.

thanks mate, i'll look into it!

Cheers Paazuzu

just had a convo with a guy on fbook, i was saying how i was having starting probs with my car. he then went on to describe every odd thing my car has done since i owned it (1.3 years) & said his was doing the same & vw replaced his earth cable on battery. after that all was fine & has been since. his car & my car are both 2007 model gti's for what its worth. id read the earth cable was suss but that was hilarious, i was like have u been in my car buddy???

Alrighty, so went through and cleaned up all the connectors to the steering rack and pump as I got my little OBDII scanner out which read steering assistance signal to high along with a high voltage code.

Since then perfection!

Paazuzu, thanks again!
