Anyone have any ideas on how to deal with this? The Start-Stop is also being deactivated (due to this error I guess).
My understanding is that the Aux Pump circulates transmission fluid though the tranny & its radiator when then "Stop" is engaged so that when "Start" happens, the tranny can operate immediately.

I replaced the battery (which was mentioned in another thread) and also cleared the error. Unfortunately the error came back. Does anyone know where I can get some documentation on this topic? Hard to diagnosis this with zero info.

TIA!
