Thread: Heater/AC Blend Motors

I used the inbuilt Diagnostics.

Simultaneously Press the AC Auto button and the Air Distribution button, while turning the ignition key on.

It runs through a Diagnostic check which includes Servo Motors etc.

No fault found.

I replaced the Heater Matrix, and I noticed that on the old one, there is a foam sealing around the matrix, so just replaced this, and now I no longer get extra hot air blowing out around the heater matrix, so I am assuming this was the problem, will give it a few 1000 km and see if the solution holds.

How difficult was it to replace the foam around the heater matrix. Did you have to remove the dash? I get a bit of warm air coming out of the vents when the climate control is switched off and the self diagnostics shows no faults.
Thanks
Peter

If you take the trim off underneath the steering wheel and the air deflector it is quite easy to push weather stripping foam between the matrix and the surround using fingers and a pointy instrument. It is fiddly but possible.

hi there

my d2 has climate control fault codes 21 & 22 does anyone have reference to these fault codes and what they possibly are ?

cheers
