Although these heaters do mask just how 'cold' the engine is. |

It is one of the reasons mpg gets knocked in cooler weather, we don't get that sort of heat for free. It works up to something like 9C outside ambient. HighlandPete |

Thanks for that info HP.
So there's an electric element in the heater unit that takes power from the battery/alternator, which forces the engine to give a bit more of its power to driving the element? If the heated seat has a similar call from the battery then I can see that a decent alternator needs to be part of this rig. But yes, December to March will be much better first thing in the mornings. |

My Mini takes about 5 miles to make any heat and it's a 61 plate.
So I keep the heater off for the first 10 minutes, or just use it to air the windscreen. Sounds like my 330 will be far better than that. |

We need a well charged battery and the 180 Amp alternator, for winter conditions, and still have restrictions put on the electrical consumers in high demand conditions. Think of it as something like an 8HP generator under the bonnet and that still has to restrict the electrical load, that is some electrical energy demand. HighlandPete |

Above 9 - 10C and ECT >85C the electrical support is deactivated, hence the cabin can appear to take longer to warm up above that ambient temperature, than below it. HighlandPete |

Really? My 435i is blowing warm air after about 3 minutes, normally just after I've got it out of the garage and locked the door, I swear they never fixed my 335d then, it was freezing for about 15 minutes, I even added a heated steering wheel on the 435i because I thought maybe that would be as bad, they did say the heater was on back order and would take 6 weeks, then suddenly after about 3 weeks it was fixed, just after I said you can have the car back lol

What I have noted, the ECT on the diesel would be 50 - 55C at the 3.5 mark, in average winter conditions, the PTC heater was doing the work, no doubt about it. The 535i's ECT is not much higher on the same drive, so clearly no real heat available at that sort of ECT, even with the heater core getting a flow. In fact the petrol is surprisingly a slow warmer, even at ambient temperatures around 10C, it takes me 12 miles to get ECT to around 100C on my typical drive. HighlandPete |

Probably a good idea with an engine as 'thin' as that one ... Do let us know once you've done it. We'll all dearly miss your erudite contributions.

In my view.
Petrol is better for performance. Diesel is better for economy. Has anyone else found this?

Whoops, sorry mate - was only kidding of course. This forum would be a lot less fun without the constant friendly digs ... :-)
And, joking aside, I drove a 428i a few months back and was amazed by how quick it was and, especially, how good it sounded on full pedal. I'd previously driven a 328i Luxury, which drove like a barge and sounded like a sewing machine. Eh, don't be doing anything too dodgy with ropes and nooses now ... :-) |
