Full agree with you, new diesel engine, especialy with "common rail" like JTD
and HDI are design to work at low temp, near 70°C.
Now a lot af cars are equiped with this auxilary interior heater, even in
France witch is not a very cold country in winter.
A petrol engine must run near 90°c but not a diesel one.
