Long time no post. Login issues now resolved. Thanks Erik!
In the last few weeks I have noticed that the familiar sound of the pump that recirculates coolant through the turbos is no longer there after shutoff. I always hear it, because I always raise the hood when I get home in the garage to let that heat dissipate more quickly. In summer I add 10 minutes with a floor fan blowing in through the front radiator.
Tech says that the intake manifold has to come off to access the pump to test it. I assume this would also enable access to the coolant temp sensors that cause the after run coolant pump to actuate. Loose wiring??
My now retired RS6 expert tech would have no problem with this. However, given that a new tech wouldn't be familiar, I worry about ending up with the intake manifold leaking or some other bad thing. Right now everything is running fine. No codes being thrown.
Should I worry about excessive turbocharger bearing heat coking the bearings? If so I may have to look for another option.
