Warming up the car?
When you first start the car (not limited to 1M), the engine revs at higher RPM before settling down to a lower idle RPM.
This takes maybe around 30 seconds, and I usually wait for the lower engine idle speed before driving off. Good idea? Not necessary? Only do it in colder climate? |

There is no technical reason to wait as far as I know. But I do wait most of the times to enjoy the cold start sound in all its glory and in full concentration. When the sound lowers down I tell myself the same thing and start driving as sane as possible

The engine warms up quicker if you drive right after starting. But, wait for the engine and oil to come to temp before going for large throttle openings or for high rpm shifts. Oh, and supposedly less emissions if you drive off soon after start up as the engine can get to operating temp quicker, and that gets the cat-con up to temp faster as well, that's what helps with emissions. Faster cat-con light up, quicker/sooner emissions control. |

I always wait for the revs to dip, first and second dip until the engine is idling quiet, takes 30seconds or sometimes more if I havent driven it for a few days.
Also hate cold start and go because backing out of the garage the car is punchier, feathering the clutch isnt as smooth as when the engine is warm. |

I always wait the 30 seconds or so at least in cold weather. If its warm out I wait at least 15 seconds or so till I go.

I used to wait for the rpms to drop, but after reading the owner's manual it say to start driving immediately at moderate engine speeds as this is the quickest way to get the engine to its operating temp.

Wow interesting. I've always let it drop first, unless I'm in a rush, but even then I sit for a few seconds.

Mind blown. On the opposite end of things: Whats the consensus on letting the car idle a bit before shutting it down after extended/harsh driving? |

FWIW Mike Miller of Roundel fame suggests traditional turbo cool down procedure i.e. low RPM gentle driving for a few miles before reaching your destination.

I always waited until the car dropped to idle. Its like a computer in my mind. Technically you can start working immediately after windows boots up. But theres another 30 seconds to a minute of extra things booting up in the background and things tend to go better if you let that all boot before you start working.
But hey, the N54 is hit or miss in terms of reliability. My fuel system self destructed at 71K miles. |

I have always kept it below ~4k rpms until the oil temp needle is in the middle (don't know what temp that actually represents, sorry) and have done this in my previous turbo charged car. Is this completely necessary? Most of my driving during an average day doesn't see the temp reach the middle...which makes the driving rather boring. It takes much longer than my previous car.
Should I worry about it so strictly or what? I would love to start enjoying my drive to work a little more... Thanks |
