hi all,
i have 2008 Q7 3.0 TDI with BUG engine 27000 km on clock and 4-zone AC system.before two month car have cool air coming from front right side duct but very less or not cool air coming from left front duct so i check the system and found rear evaporator leak replaced it and fill gas the cooling is perfect for both side now after 2 months car came back with same problem no cooling from left front a/c duct.is there still a leak in system or something else.here is the measuring values from scaner when it cooling and when not cooling.
when cooling.
1-control current of AC compressor regulating valve N280 0.715 A
when not cooling.
1-control current of Ac compressor regulating valve N280 0.715 A
when cooling.
1-pressure in refrigerant circuit 15 BAR
when not cooling.
1-pressure in refregerant circuit 11 bar
sorry i donot have green liquid to cheak leaking but with making soap?
