Hi, i just bought a Audi a4b8 2009 model car. There is a problem with the car air condition. it stops working suddenly without any problem before that. so, i went to a garage at my neighbourhood, they diagnose using the computer. The fault code appearing for the air cond system are j519 vehicle electronic control module faulty and a/c pressure/temperature sensor faulty. The mechanic changed the pressure sensor but still the same. he said the compressor wire no power supply. then, he also checked the j519 module, but no burning or damage with the module. So guys, i really need your help to get my car back to the road. I really miss my car so much. Please give me some solution or idea to get the problem solved. Thanks in advance.******10-24-2013, 02:01 AM
