My self-levelling rear suspension on 1988 100 Avant has become rather bouncy lately. Even my sister driving behind noticed it.
It seems to have got worse since I changed the hydraulic pump, but that may be coincidence.
Ride height isn't far out, although it does sag when parked.
There are no major leaks from anywhere.
I've not found much information about the system, particularly what faulty parts gives what symptoms.
Does anyone understand how this system is supposed to work? (I understand the basics).
The following thread about a Merc system makes it sound very similar to the Audi one and points to the spheres...

I guess the spheres are like the brake bomb, and they lose pressure with age.
