Have a Passat NMS 2012 in the shop because it overheated pretty badly one night recently driving on the freeway. I found the coolant pump impeller loose on the shaft, replaced it with timing belt service that was well over due but, I don't know if that is all that is wrong.
Owner complained that the heater did not work on the occasion of the overheating incident but said it was not previously a problem. I imagine that the heater core would not necessarily get hot if the pump was not pushing coolant.
The EGR cooler has been removed along with the exhaust, turbo back.
I did discover the flaky residue when I strained the coolant that I extracted.
As it is now the coolant temp seems to be running about 204*F (96*C) on this day which is 77*F...not really hot. Flat ground, pushing it on occasion at WOT... cooling system should be able to handle it, no? radiator fans are coming on.
Here is the readout via VCDS:
Address 01: Engine (03L 997 009 J)
16:18:33
IDE00025 Coolant temperature 96 °C
IDE00192 Coolant temperature at radiator outlet: actual value 46.3 °C
IDE00194 Coolant temperature at radiator output: specified value 95.0 °C
Does that look like too big of a temp drop for the thermostat to be working correctly?at all?
