My '96 A6 Tdi has just developed a problem with the climate control.
In "Full Cold" it does what it says on the box, but with any
temperature selected it blows fully hot - it does this with either AC
selected or not.
The diagnostic code on the climate control unit itself displays 8.5 -
"Temperature Regulator Flap, static block".
Does anyone have any clues about fixing this, or can anyone recommend
someone in NW England (Cheshire) who might be able to cure the
