Arrow Air Con Problem

Hi I am new to the forum so hope I can get some help with 2003 a8 air con problem........Aircon did not work when I bought the car, had it regassed, no difference..so took to local garage who are pretty good, he put on Vag-Com for free(result)........it showed the following faults............
00819 high pressure sensor...open circuit
00727 potentiometer in defrost flap motor
00728 left centre vent motor position sensor
00735 recirculation flap motor position sensor
01851 position sensor defrost/upper body shut off flap motor
08169 left rear cold/warm air outlet motor position sensor
01592 sensor air quality
Now the garage checked and found that the condenser had a bad leak, so this is being replaced, as is the high pressure switch, before I start scratching my head and possibly ripping the interior apart for nothing, can anybody tell me is it possible all the motor/sensor faults have one cause or do I really have so many....if the latter is the answer where are they located and how do I access them. thank Ken

Hi
All I did was change the condenser which was leaking and while it was out changed the pressure sensor at the same time, this seems to have corrected most of my HVAC problems solved
