Climate Control Fault Codes

[Ivor_E_Tower]

Don't know if the aircon is the same type as fitted to the Audi A2, but I've just found this on another car help site and it may be relevant:Thanks to the Audi A2 owners club site for this:

 

- Accessing On-Board Diagnostic codes:

Press and hold the recirculation button. Then press the manual flow control up arrow. You should see a 1c. Press the temperature up ("+") or down ("-") buttons to select a code number. Then press the recirculation button again. The value should display. Press the temperature up or down button again to display another code.

NOTE: Air Flow Motor (V 71) and Potentiometer (G 113) are not installed in USA/Canada vehicles. Disregard values displayed for these components.

Blimey Ivor, did you cut and paste, or was that a marathon typing session :angry: If it works that looks like useful info, thanks.

'twas cut and paste (plus I have printed it, although I hope never to have to use it!)

Hello, I am new in this forum.

 

It looks like that you have very good infomation on the cc. My problem is, that the cc display changed vorm Cels

[Guest SA Intruder]

Yes, I've covered this before (use search?)

 

Press Auto and Econ buttons together.

[Guest carney]

just found out on mine you can change it from c to f by pressing a small button on the right hand side of the ac control panel its like one of those to change a digital watch or clock

i used the tip of a pen to press it in

i thought it was to take the front panel of the facia at first hope this helps

Hi Ivor,

 

Just tried the diagnostic procedure on my '98 2.3 Ghia, with no luck.

 

Somewhere I remember reading that the 2.0 & 2.3 engines are made by Ford; would that imply that the aircon is like to be a Ford one too ?

 

Also would the "VAG-Com" shareware software be any good for interrogating the aircon, assuming it is a VW system ?

 

Many thanks,

 

Yuri.

Disappointing to hear that the Audi fault codes/diagnostic does not work.

The aircon system is VW, different compressors are used depending on the engine. VW 2.0 and Ford 2.0 engines are different. 2.3 is a Ford-only option, made by Ford.

Don't know about VAG-COM software, sorry.
