Hi all thanks to a friend I managed to get DIS working and was going through the infinite menus and noticed that I had this error.

Auxiliary water pump:: Faulty or no signal

This component is located under the aircondition and climate control category. Any ideas what it does and if I can live without changing it ? Thanks.

If the pump isn't leaking coolant you probably shouldn't have to worry with it. Your heater's efficiency will certainly be diminished.
Hopefully a diesel owner will correct me, but, I think the aux. pump circulates coolant through an electric heat exchanger till the
engine gets up to temperature.
GL!

Any diesel owners have an idea if the aux. pump also cools down the turbo after the engine Is switched off ?
