Hi all.
Anybody can help me with this information about 1.8t BAM engine aux/secondary water pump wiring?

Many thanks fukenbroken
So it works at the same time with fans(after 97-98 degree) when the ignition is on and after ignition is cut , only when the fans are runing, correct?
I found some post on the other sites where people said the aux pump works 10 minutes , but it is hard to belive that.
Have a good day.

Why is it hard to believe? It's to circulate coolant when the engine isn't running, not aid it when it is.

Anybody know coolant fan relay module from BAM(with auxiliary water pump) is different than AUQ/AUM(without auxiliary water pump)? I think they must be different because ecu must knows to open/close a different relay/timmer for this water pump.
From ecu to auxiliary water pump on BAM is not any connections/wires.

There are alot of revisions of the 1J0919506*
Have a look at yours or the pictures in google. If you see WP written on one Pin then it will support the Waterpump.

Hi and thanks AEF. I checked the wires from my old skoda octavia 1 with AUM engine. It had 1J0919506K on it and i saw all wires are connected in this 1J0919506, but the ar not had seconbdary water pump. I thinked it must not had an wire plugged in pin 1 - WP from 14pins connector of 1J0919506. this wire must goes in water pump, right?
