I have noticed my TDI will not warm up while idling. I just picked up a coolant heater from a friend for free (is new, but he totaled his TDI and won't be needing it). Anyhow. I was driving yesterday on highway for about 2 hours in the cold northern parts of Michigan, engine running right at 190 the whole time. I pulled over to rest, potty break for kids, snacks, etc. Left car idling while doing this to keep heat on for boys (we travel with them in comfy clothes and no coat in warm car). Any how, by time we idled there for twenty mins and were ready to leave, the temp had dropped down significantly (I would guess 120-140).
It seemed strange to me that it would cool down from warm while idling.
Does this seem normal, or maybe a thermostat issue, or....
