Hi Everyone,
New owner of an Audi A4 B6 1,9tdi, been kept busy sorting it out after the previous owners garage seemed to know how to invoice but not carry out half of the work.
I am really stuck with my AC after re-gassing the AC system and repairing the High Pressure Switch fault with a new sensor the system still wouldn't function. Further investigation I found that the front of the compressor had disintegrated and I could spin the internal shaft by hand, I replaced the compressor and receiver dryer but after a re-gas have found that the system still doesn't work. I am getting voltage at the compressor 9.6V when turn 'Econ' mode off but the circuit pressure remains static at 5.0 bar.
I was hoping others may be able to share some previous experience on fixing their AC? I have included a couple of screenshots showing the system functioning from VCDS, everything seems to be working but no cold air?
Thanks in advance for your help
Dean
