PD140 idle, temperature drop?
Hi all,
having driven at 30mph speeds for 15 minutes, would you expect the engine temp to drop from 90c if you sat there idling with the engine on? Maybe you would as it's diesel?

It dropped from 90c to 80c, before I decided to turn the engine off because it was dropping. Although not visibly moving, the needle was dropping at a noticable speed.
I'll experiment some more when I get the chance.

Well given that TDIs never warm up when you leave them idling on a winter's morning, then it wouldn't surprise me....
I guess it will also depend on how much heat you're taking out of the coolant by using the heater inside the car.

I have this too, spoken to a few people, i work for bmw and bmw have to put an auxiliary heater in the heater box because the diesel engines are to efficient and they will cool down on idle so there is nothing wrong with your car, spoken to seat and they said the same thing

i was under the impression the temp was regulated to 90c. This would answer why it doesnt cool down at idle.
