Hello together… Had already written that my air conditioning system is not running very well. Have now finally had the errors read out and deleted. The errors in detail… -B1 1-3-2 channel air sensor driver side -B1 1-3-4 channel air sensor passenger side -B1 235 valve switch for convection air -B1 325 valve switch for convection air active for too long -B1 411 blower motor mech. or too blocked by overcurrent (by new replaced / preresistance also) -B1 414 barrier air sensor driver side (extended) t and cleaned) -B1 417 Static air sensor passenger side (expanded and cleaned) The errors were all deleted, but it didn’t bring anything. The Werkstattt tried it again with another control panel, but it didn’t do anything. I wrote behind the errors above, which we already did. Unfortunately, I can’t classify the first four mistakes at all. Someone an idea?
