i have a 90 h plate gti 8v with jetronic, i can see nothing like this on mine, (jetronic dosen't use a crank sensor it gets its timing from the dizzy i beleive) i would be inclined to agree with j.w and go with the swapped g/box theory.
wasn't 90 the year of changeover from motronic to bosch jetronic?
and yes the gti 8v has 2 earth straps 1 small 1 large, why?? i dont know, of which both mine were badly corroded/broken.

Thinking about this I've never seen it fitted to an XU, only a TU, but from what I can make out in the picture it looks more like the sensor for this than the crank position sensor required for the Motronic system.

The crank sensor for Motronic looks like this:

Compared with the one on eBay that's for the 'diagnostic socket':

Either way it's not required.

Well thank you all.
I'm going with the diagnostic socket theory, as the last owner assures me it's never had a gearbox, and he's had it from new!
I have the full history of the car and nothing to suggest it's had a gearbox.

I think the 'diagnostic socket' is the right answer, i've pulled the sensor out and it look exactly like the 2nd picture as it just pushes in - no bolt to hold it in.
The wire has broken off, so I'll will try and find the other end, which I will expect to be the 3 pin connector

I have to disagree Pogo, it's definitely had a gearbox at some point, in fact I'd go so far as to say it still has one! :mrgreen: :lol:
