After the replacement of the ZV pump, the radio function of the ZV no longer works, which worked before. Now you can open and close the car again without having to open any door by hand, but only with the key in the door lock. Before the exchange the pump was heard working unsuccessfully and the doors remained closed. Now the doors don't open and close by radio anymore, only when you turn the key in the door lock. What could be the cause here? ==References== Cable to pump or...? Tested with several keys - so no empty battery.
