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?
