Ok I have four error codes reading out of the A/C unit.

These are:

03.1
05.3
15.3
18.3

The manual says:

03.1 = Interior Temperature Sensor, in Instrument Panel, static open, see 02.1
05.3 = Outside Air (Ambient) Temperature Sensor, front, sporadic open
15.3 = Air Flow Flap Motor Potentiometer, sporadic open
18.3 = Fresh air blower voltage, sporadic

Does anyone know what these mean in plain english? I have a Audi A4 2.4 v6 98 R reg. I'm trying to fix the problems but i don't understand where the errors are coming from has the manual does no give speicifc information.

Any help will be appreciated. :w00t:
