I came across this photo in a GTS brochure and
I hadn't seen this before. Does anyone know the function of the **** in front of the hatch release? Thanks
Not vacuum or electric operated, electric version has a small switch on the pod to operate them.
This type is hydraulic and is a common failure point due to the plastic lines breaking through age.
Definitely factory and electric in my 1990 S4. If you have a switch on the pod to adjust the vertical aim of the headlights that is definitely aftermarket.
The later electric version is much more reliable than the earlier hydraulic system. Some people have converted to the later type or installed it in USA cars.

The early ones must be a right bucket of poo!
The later ones are invariably failing because the plastic ball socket on the head lamp unit turns to dust with age and as I am aware there is currently no fix available for it.
It is on my "to do" list as and when I can get round to making something to fill the void. At the moment I have jammed a rubber packer in the mechanism to stop it from bobbing around..

There was never a stock system with a switch on the Pod. The Hydraulic and electric systems look generally the same as far as the control **** set up. This one actually looks like an electric system (there are subtle differences). The electric system is indeed more reliable than the earlier hydraulic system. The hydraulic lines need to flex as the pods move and they eventually get brittle with age and just fracture...
Yes I had the hydraulic system in my old MY88, and electric in my current MY91 S4. The controls for both almost identical and as per the brochure photo - pod switch was never standard.
The hydraulic system never worked. The electric one works very well, but I had to replace one motor when the servo circuit started ‘hunting’. The servo compares resistance of track in motor which varies as headlight moves, with resistance selected by switch by parking brake.
Posts here put me off trying to repair hydraulic system. In spite of my 928 OCD! It seems a hopeless quest and candidate for flakiest system on the car along with rear tailgate release!

What is the function of this ****?
