After getting the error code #23 , I opend the case of the charger, welded out the internal thermal sensor ( 81 220 W09 ) and checked it.
Unfortunately I couldnt find any misfunction. At 22 degree it has nearly 2k and the value rised under higher temperature.
Possibly the error code includes also some other failures, but I couldnt find any further details. Is there an option to clean the stored errors?
Best regards
Thomas
