Hello,
just got back from a trip an got some stuff for the LHD aircon. did i forgot something from hardware? so what do i need to install the set? part no? does this fit under the facelift front dash?
I'm not familiar with the LHD pipework but it looks like you got it all. Looks like the early climate system - I think you can easily upgrade to digital climate control if you want.
You forgot to get the main wiring harness, but I think you got a cruise control ECU in the deal by accident
You need the hard pipe from the top of the condenser with the red & yellow pressure sensors - maybe you have it I can't quite see if it is hidden behind the compressor.
Oh yes you forgot to get the coolant temp sensor from the heater hose in the engine bay, but no problem it is not expensive.
The engine bay harness for the AC is also missing - on the S2 at least it is part of the main rad fan harness. You can easily make one though, it's only 5 wires, 7 if you use the coolant temp sensor.

behind the compressor. not right ones?
so if i want to update it to to digital contro system do i need the other box? or i can use this one and swap the flap engines from digital box?
my previos owner of the car idid put the digital box and controls in it but he also did cut the pipes of the box
the harness and the temp sensors are all the same in audi 80? or do i need some special stuff from s2?
the best stuff about the aircon... it only cost me 80 euros

It does look as though you've got most things but you've a decision to make. This indeed looks like an early climate system that uses vacuum and vacuum motors to move the flaps on the heater unit. If I were you I wouldn't go to all the trouble of taking the dash apart to fit a vacuum based system, I'd get hold of the central heater unit from a digital based system from an 80 or early A4 along with climate control computer/display and loom. There'll be plenty of LHD units in your local scrappy.

the loom and the digital system is in... but my s2 is a 90 model.. so dont know if i go to original look or go to a facelift version... the dash must go off so or so... can i swith the vacuum controls to eletric ones? are the pipes bolt on to the newer unit or its a custom?

On the early system the temperature flap is controlled by an electric motor but the rest of the flaps are driven by vacuum solenoids. I don't know if you can change the vacuum solenoids to the electric motor driven flaps you need for the digital system but there seems little point in trying when you can get the electrically driven LHD central heater unit relatively easily all ready to connect to a digital face unit, motors and all.
If you mean the pipes for the aircon, they don't change as that unit stays the same.
Think of the whole heater system being made up of three parts: the inlet duct and fan motor, the evaporator and then the heater unit. All three join up to each other with clips.
It's only the heater unit with the flaps and motors on that you need to change. If you get a later heater unit with the electric driven flaps on it, that new unit will just clip onto your existing two other units.
