I keep getting this code 80436B "Auxiliary water pump: Short circuit to ground" popping up in my code reader, but never have had a check engine light. Code comes back in a day after I clear it. It is for the turbocharger cooler - anyone have any thoughts on this - should i just ignore - am afraid I am killing my turbo in the long term...

RealOEM or NewTIS or trace the pipes.

In the E70 35d the auxiliary coolant pump is apparently directly up stream of the HCV.
