Hi There, I have an audi a3 sportback tdi 1.9 2007 model.
Econ light stays on after engine starts and does not turn off after pressing the button. I did a scan on VAG and no faults came up. I did some output tests and I got the following results with the car stationary and engine running and the econ button would not turn off after pressing it:
0.000 A A/C Regulating Valve (N280)
0.0 % A/C Regulating Valve (N280)
4.5 % High Pressure Sensor (G65)
1.0 bar Refrigerant Pressure
35.0 Feedback Value (Actual)
36.0 Feedback Value (Specified)
38.0 Minimum Position (Lower Stop/Cool)
211.0 Maximum Position (Upper Stop/Hot)
60.0°C Coolant Temperature
0 A/C Compressor Regul.Valve (N280)
The reading were obtained while temparature setting was set to 'LO', I opened the bonnet and both radiator fans are not spinning, which I believe is because the air con compressor is not activated due to econ light being on. Hope I don't need to spend £££ to have what ever is wrong fixed. Before I did the scan I was told I have a dodgy econ button, but this works while engine is not running. I was also told I maybe low on gas, which I believe isn't a costly fix.
Feeback on this will be most appreciated. Cheers
