That`s why diesel engines are much heavier than petrols (rigid cast, thicker walls) and they take longer to heat up to normal temperature.

You wont notice that since every modern diesel has built in an additional (auxiliary) heater.

My dad had a 2001 530d (navi professional) without the optional auxiliary heater with remote ( 1200).
A buddy BMW service technician told us, every BMW diesel has the additional heater built in which can be upgraded as fully stand-alone auxiliary heater. And the best:

It was only a software update! Now you can fully operate it from the navi screen, you just have no remote.

So why does the heater cost extra 1xxx on every BMW, either petrol or not?
