Hi Pantelis;

    I don't know the climate control system design on your RS2, but I had a
similar problem on my '91 200q. The error code set was "Temperature flap
regulating motor open circuit" or something to that effect - codes 7 and 15
on my car if I recall correctly.
    The problem was a bad contact in the temp flap regulating motor wiring
connector. I pulled the connector apart, cleaned it with contact cleaner,
applied Stabilant 22A, and the problem was solved.
    You may have a similar problem if hitting a bump restored the
temperature control. This is often a sign of an intermittent connection.
