Hi,
I am looking for some guidance regarding my air con on my 2006 Audi A3 2.0 TDI Sportback, 8P.
A few weeks ago I noticed that the air con was no longer giving out cold air. There is no clunk that you would normally get when the compressor kicks in and the separate fan on the rad for the air con does not kick in, though it spins freely.
Along with a very nice and helpful local garage, the following has been done so far:
1. Checked, tested, cleaned and re-seated several fuses next to the driver's door - the ones that say they're related to air con. Fuses checked in engine bay.
2. Scanned for codes using garage kit (possibly Snap On). There was a code 01320 which related to the air con controller, so I bought a 2nd hand replacement from eBay. Cleared all stored codes, still no air con. Code 01320 did not return though.
3. The air con gas has been checked - the correct amount was in there, no leaks.
4. No HVAC codes stored (except for the usual aux heater)
5. The compressor was replaced about 3 years ago.
Could it be down to a relay? I cannot seem to find any information anywhere about the Audi A3 8P having an air con relay.
If the compressor has failed (again!), would that definitely be giving a code? Same for pressure sensors?
With no codes getting thrown, it would seem to be something simple, but we are running out of ideas. Grateful for any pointers!
