Warm up time

Hi all,
I'm just waiting for my car right and just dreaming about it today... Then I wondered how long I'm gonna have to warm up during winter. For my prior car I just warmed up until rpm went just below 1k.so is that ok for BMW?
This is first BMW so I was just curious what others do during winter.

according to page 166 of the user manual:

Drive away without delay
Do not wait for the engine to warm up while the
vehicle remains stationary. Start driving right
away, but at moderate engine speeds.
This is the fastest way for the cold engine to
reach its operating temperature.

Interesting.

I was wondering how the stop/start (Eco function) engine works if you're just warming up your car in your driveway. I am not sure it matters now, but can anyone offer up some input on that?

Despite what the manual says, when I had a one-on-one discussion with a BMW tech a few weeks ago he encouraged me (on a cold start) to let the engine warm up for at least a minute or so before driving because oil needs to reach the turbocharger.

I also asked the tech about shutdown. He said that it is unnecessary to let the engine cool down before shutting it off.

On any modern engine it takes all of less than 5 seconds for oil to start circulating. Gone are the days of leaving a car warming up for several minutes. Get in, start the engine, by the time you are done putting on your seatbelt and plugging in your phone, the car is ready to drive.

The ASS doesn't kick in until the engine has warmed uo sufficiently. It also doesn't work when the outside temp is too high or too low. There are several other situations as well which off hand I don't recall. The manual lists them all.

I agree that cars warm up more quickly now than before. But in any event, from a cold start I don't touch the gas pedal until the (fast) idle kicks down. In the F30, that's about the same time that the exhaust flap opens.

Another point, modern cars (catalytic converters) are MOST pollutant during cold start-up. This is another reason modern cars do not require any warm-up time. Manufacturers have designed the emissions systems on modern cars to warm up as fast as possible in order to reduce tailpipe emissions. This is another reason manufacturers clearly state "Start driving right away".

There is no need for this. There are legions of BMWs, both turbo and non turbo models operating today. Most people just turn the car on and go. You are just wasting time and gas!

That would work just fine. Shouldn't take more than a minute and a minute is not excessive.

For me it is not so much about letting the engine warm up, as it is being able to see. I often experience frost on the inside of the windshield if the car is left outside. Also if I get in from a warm building the moisture on me will cause the inside of the windshield to frost up on a cold vehicle. Of course the last few days it had been about -30F (-34C) here overnight. So until the defroster produce enough heat to clear the windshield, I have to let it idle.

Once that is done, I drive it slowly to let the rest of the drivetrain warm up gradually.

Plus, on really cold days, I like to start it up, go back in the house, get it all nice and toasty on the inside of the car, and then go back outside and drive away...

I have done this all my life for every car I have ever owned.

I just noticed that it takes 10-15 minutes for N20 to fully warm up. Even though the outside temp is in 30s my other car is good to go in no time. My 328's oil temp gauge doesn't even move during the first 10 minutes of driving.

The car feels fine .. just wondering if anyone else noticed this.

they're all like this--the thermostat doesnt open until the coolant reaches the right temp. it takes a little bit for the temp gauge to start to move. the dme will limit turbo boost until the engine is at the right temp, so just drive it

It would be nice and toasty without the warm up time if you had the CWP.

The oil temp taking 10 minutes or more before it even starts moving freaked me too. I thought the gauge was broken. I asked my SA and (of course) he says it's normal. He also said that the coolant gets up to temp much faster than that, but since there is no easy way to see the coolant temp, I don't really know.

I just take it relatively easy on the engine until the oil temp is normal (about 205 degrees F) just to be safe.

I just wait until the idle drops to about 600, which is about 1 minute.

you def should let just the engine warm up and have it sit. The transmission will still be cold. Start it up, wait 5 seconds for it to stabilize and just go. Keep the revs below 3k and it will warm up just fine. Modern synthetics flow even at very low temps so I wouldn't be too concerned about the turbo not getting oil.

It seems ironic that when it comes to the break in procedure most of us follow what's recommended in the manual , slamming any one who says otherwise , arguing that BMW engineers know more about the cars they themselves build and design .

Not so much for the warm up procedure where it clearly states ...Don't wait - drive . I've seen a similar number of comments arguing AGAINST what's mentioned in the manual regarding the warm up procedure compared to those arguing FOR what's written in the manual regarding the break in procedure .

In any case unless you are driving in an emergency it takes at least about a minute to pair your phone , adjust the tush warmer and set the temp . before before you start driving .

Soooooo it is frigid in Illinois. You're recommended to bundle up; drive cold until car's warm enough to cut loose a btu, maybe more.

Not me. I like the thick layer of evening ice 'n' snow to be melted off my glass before motoring. You should too.
