Looking for: Aux water pump install

I been searching but maybe I'm not searching for the right things. I'm looking for a DIY for the auxiliary water pump. I threw a code this weekend and it led me to:

I have changed the aux pump last year,
because of the same error you have: 00A6D1

Partnumber is: 64118369806

You will finde the Pump near the Firewall of the Driversside (LHD).
After you have removed the Airfilterbox you can see the pump.
Remove the connector on top and the two waterhorses (i used two clamps, so no need to fill up coolingwater). Al in all very easy and max. 1 hour of work.

Had the A6D1 code coming and going but now seems not possible to clear anylonger. Noticed also you have an 2011. As the "Rest" button apparently was taken away from 2010 (I had it on previous bimmers), when is this pump used?
The Rest button enabled the pump with ignition off, but in our case one have to have it on anyways correct?

The pump is a good $300 over here so starting to wonder whether I actually want to replace it as I don't see the point with it... You?

Could be used for cooling also as our cars use a mechanical water pump, but the Aux Pump is electric which can be useful to cool down when the car is off.

Yes, maybe thats the case when the fan is still on after engine turned off, fan wouldn't have much to make noise over if the coolant wasn't moving, thanks.

Another "use case" - even without the Rest function - could be during stop/start, maybe. Coded this our long ago so in my case do diff.

Thanks again though. My fan rarely stays on after turn off (Nordic climat, rarely over 25C Summer...), but will definitely keep this in mind as possible reason to get a new pump.

Cheers,
Nik
