Climatronic for Volkswagen Golf IV

Hello,

Perhaps you can help me with my problem (unfortunately, the search function doesn't return anything on this topic).
In a Golf IV Estate with Climatronic, the air conditioning only cools while the car is moving; it stops cooling when the car is stationary. According to the diagnostic data, the reason for this shutdown is that the engine speed signal is not being recognized (deactivation condition 5).
In addition, the following error code is stored in the system's memory:
01206 - Signal for ignition switch-off duration.
37-00 - defective.


Which cables or connectors should be checked in this case (unfortunately, I don't have a wiring diagram available at the moment)?

Thank you in advance!

Hi,
Do the electric fans work when the air conditioning is on?

"This error has nothing to do with your problem. I also have a customer who has had this error stuck in their memory for years, and their air conditioning system has been working fine all that time. This signal is just a minimal correction signal, as insignificant as the solar sensor."
