Climatronic issue

It would be good if you could just plug in another head unit to see if that fixes the problem.

You can also get the headunit into its own diagnostic mode and see what codes it displays itself.

I wonder if its just a simple wiring fault in the harness from the outside air temp sensor - incorrect resistance would give wrong temp display

vw part number is 3B2 907 044 B
Hella number is 5HB 007 617-11 (the dash 11 part changes between types)

Will check it out in a few minutes when I have had my tea.

Ordered a replacement unit today for $83 delivered so will see how that goes............

Well the unit arrived today and i was a bit concerned about its condition but a quick clean up and all looks fine.
5min install job and so far it seems to have solved the issues but I am yet to hook up VCDS to check what the sensors are reading

Well not 100% new unit continues to log errors and flash crazy every time the unit is turned on . Unit dose display correct temp and dose operate the a/c but doesn't control fan speed correctly (all out or nothing ) doesn't see the light sensor on the dash and dose the flash thing on start up.
So emailed the supplier to see if i can get a replacement

Replacement arrived today but no luck they sent me the wrong unit (3B2 907 044 A instead of 3B2 907 044 B )
So seems to work well except that it doesn't activate the a/c ;p .......back to the drawing board
