I recently bought a 2007 Audi A4 2.0T where the battery died and the AC stopped working. After doing a lot of research, it all sounds like it is probably related to the comfort control module. However, I cannot figure out how to get this software to program the comfort control module.

I did have to change out the compressor since the clutch had sheared in two, and prior to changing out the clutch I realized that my system wasn't holding a vacuum, and after changing the compressor and the orings on the compressor it still doesn't hold a vacuum. Short of manually powering the clutch to get the die through the system to look for leaks, I was hoping to be able to program the comfort control module.

All help is appreciated.

Thank you for your immediate response.

Below is my AutoScan,

I have been having issues with my Turbo, I have had the following codes P0234, P0441, P2004 and P2008 (I haven't had the last code since I changed the thermostat, so I don't recall if I got that one right.)

So I have changed the thermostate, and the purge valve (that didn't do anything for the P0441 code)

As I stated the battery died, so I had to reprogram my key

Is your car FOD modified tuned?

Better check N80 + install and that hose routing is correct............

Since I bought the car used, I haven't invested in a manual yet, what is N80?

Is FOD the same as the MIL light on the dash?

I"m not exactly sure why the P0441 comes on, it doesn't always come on, I can drive 200 miles straight with it off, and then when I'm on back roads it kicks on.

I also discovered a wire that appears to have been snagged by the belt or fan the number on the harness is 8E0 971 073 K TAB 010 962 Q. I haven't figured out where the wire attaches to yet, but it is 2 small brown wires.

This forum is not a substitute for the RTFB.

Get it and print to PDF at ERWIN.

N80 is the EVAP purge solenoid.

Tests can be done in VCDS here. 0x01-04-070 EVAP and 071 for LDP

FOD = Foreign object damage.
https://en.wikipedia.org/wiki/Foreign_object_damage

I recommend you get an RTFB and search N80 in WD + read how stuff works in SSP.

Please reset your fault memory in all controllers and repost your new compete auto-scan.

Thank you
