Auxiliary Water Pump Not Coming On

Hey everyone I've got an odd problem with my Mini, I think I may have messed something up when I first started poking around with NCSExpert and accidentally hit process car which of course started going through each ECU. Luckily it bombed out relatively quickly but ever since then my Auxiliary water pump doesn't appear to be coming on after shutdown. I coded the CAS, Kombi and FRM back to defaults afterwards to clear those guys but I'm not sure which ECU controls the Aux pump, does anyone know which computer does and if I can turn that back on?

Trying to avoid going to the dealer as I have a Manic tune and don't want them to possibly overwrite that in the process of updating the computers.

Did you ever get the recall done on the Aux. water pump? Might have just gone bad

I did actually, had it done 24k ago. Any chance it would have failed already?

the DME controls the aux water pump. you could go back to NCS and reset the DME.

So turns out my Aux pump does still work, didn't have to change anything. I guess the last mile home before parking at 10mph is enough to cool it down enough to not need to run the pump so I was never hearing it. Did hear it running yesterday so we're good.

Yep, it does not run all the time, just after the engine get warm after a drive, short trips for like 1 min sometimes it does not kick on after you shut down the engine. Same way with the fan,
