Previous owner had reversed the send/return pipes to the levelling valve
causing "burst" shockers. I have replaced the shockers and for a few
moments, all was well but then the suspension went down and it seems as
though the levelling valve doesn't change the height anymore (and worse,
it's dribbling through the spindle).

I probably need a new one but does anyone know if it's possible to
recondition these valves? Or better still, does anyone have a good one going
spare?

The part number is 443 616 151 if it helps.

Sorry I can't help directly, only share experiences...
There seems to be 2 types of problem with these valves. Either they leak
or seize. On my '88 A100 CD Avant my valve was leaking very badly and
the suspension used to sag down when not used. I replaced it with a
second-hand unit as new ones are pricey. I never came across re-con units.
The replacement unit was fine for a few months (if a little high in ride
height) but then I noticed it was not compensating for heavy loads.
Closer inspection reveals no leaks but that the spindle appears to have
seized. I can't budge it and in fact the splines on the spindle have
been broken off by the bracket moving on it. So no more self-levelling.
If you decide to replace this valve be prepared to spend ages under the
car. It's well difficult to get to - I was weeks doing the job!

Fortunately the valve on the quattro version is mounted on the opposite side
of the rear axle and upside down which means it's very easy to get to all
the pipework and securing bolts. I've bitten the bullet and ordered one from
VAG since it turns out the quattro valve is slightly different to the
non-quattro. The part number has an E tacked on the end. The chances of
finding one second-hand are probably infinitesimal so didn't have much
choice. £277 for quattro as opposed to £200 for non-quattro, that's an
expensive 'E'

It'll be worth it though, the car is absolutely brilliant otherwise.
