All dynamic seats stopped working - the pump?
I'm thinking that the error I posted in another thread is not the main problem, since ALL the seats stopped working and the error is only for the Driver Seat.
(Error 9200 Driver's Module Carrier for the Backrest is Defective - I'm thinking it's part number 221-910-22-75 )
I clear the error, does not come back. I try to inflate the individual cushions/bladders with the Star - none inflates, message "Failed for unknown reasons". All the bladders in all seats give the same results (Star connects to all seats).
I've also updated the s/w in the driver seat (often s/w is buggy in 2007 like not remembering the lumbar support and newer versions fix multiple problems), no change.
I try to connect to the pump - Star fails to connect (multiple times). So I'm guessing the pump module in the trunk is bad. But all soft closing of the doors and central power locking is working - my understanding is that the pump is shared between the seats and the door locks? So the pump must be working in some way. Also, the Star does not show any pump errors!
I'm thinking the 9200 error is not the main problem, maybe the pump is. What to test/how to move from here if ALL seats don't work? How to definitely determine if the pump is good or bad?
