Flashing Airco

[fmjpf]

Does anybody know what could be the reason for a flashing green Airco button (the snowflake looking button)?
Even though it has been regassed, BMW said it is an electrical fault and the only way to assess it would be to remove the complete dashboard which of course eats up labour costs....
