I miss my diesel 330d fast heat up, as the 535i has to get heat from the engine, not an auxiliary electric heater, so much slower. It is the only negative about the petrol engine, slow cabin warm up.

And to think it used to be a diesel issue a few years back, when we'd wait forever for cabin heat.

As you can tell I wasn't aware of the heating element.

Thanks!
