Finally fitted a replacement sump guard today it came from a 1999 1.8 petrol. It all aligned up except a for couple of bumper fixings which i cut off. Checked it for clearance etc and drove 10 miles home no problems.
Then went out tonight and on full lock I have one hell of a vibration coming through the steering. So it looks like its coming back off tomorrow

Up to now i have done 3000 trouble free miles
