i stand corrected.
it has to be something about locking the rear drive, so that the prop cant turn.

It’s 5mins to pull and check the halfshafts, I thought they were supposed to be the weakest link rather than any gearbox shafts?
It's not driving in normal rear 2wd.

That had me too does that mean you can drive it in rear wheel drive with handbrake on or just push it ?
The engine is turning the gearbox, which is turning the rear output of the transfer box. If the handbrake is on it will stall the engine. If the handbrake is off, I'm betting that it's turning the prop, which isn't driving the car because a half shaft or diff is duff. The car will move with the handbrake on because the wheels aren't driving the propshaft.
Back to broken halfshaft then[/QUOTE]
that has to be the easiest thing to check??

Yup, although it is faintly possible that the spline could have evaporated in the prop, but I ain't seen that happen myself. Although I'll bet that JamesM has!

for the hand brake not to work,there must be a half shaft or diff issue, hand brake locks drum and so prop to the transfer box case,the s3 is in the building
unfortunately arrived as it got dark but I had a quick look underneath and the prop and joints all seem fine.
in rear wheel drive the handbrake doesn't work. with the handbrake on in rear wheel drive the car is mobile. take the handbrake off and it doesn't move. put it in gear with the handbrake off and you can lift the clutch up all the way and it doesn't stall. put the handbrake on and it stalls.
in 4wd handbrake works as it should and car will move around as expected.
with car in gear in rear wheel drive the rear prop is not turning
so I am guessing this is a transfer case problem? or something between the transfer case and prop
in low box or 4 wd hand brake will work on the front axle
yes, if I put it in gear in rear wheel drive it doesn't go but if you put the handbrake on it drives in rear wheel drive as normal
I think we're in complete agreement James, I just didn't mention using front wheel drive to get the handbrake in action because that was covered earlier in the thread.

is it a std series transmission
as far as I know it is
Earlier in the thread you said that you had to put in low and yellow knob down to get it to drive?
indeed I did, that was when it was down in Exeter when my daughter was driving it and I was getting her to put it into 4wd over the phone.
the moving about in rear wheel drive with the handbrake on only came to light when it had been recovered to here and I discovered it more by accident than design.
it goes in low which as I understand it is automatically 4wd, and also goes in high with the yellow knob down

THIs proves HALFSHAFTS BOTH OK and so is rear propshaft so rear drive is only when handbrake on this needs a head scratch
