I do this too. I just wait for idle RPMs to drop and the time varies with temperature. I also noticed that the exhaust from cold start only comes out of the right tailpipe, which produces a lot of noise. After awhile, the left tailpipe opens up. Does this help warm up the engine faster?

I also asked the tech about shutdown. He said that it is unnecessary to let the engine cool down before shutting it off.
This may be right. Past two weeks we've had nights in the 30s. In the AM my F30 is beyond sluggish. I've made it to work (5-6 miles) and the oil temp is still below 160.

If you are driving that short of a distance and the engine is not coming up to full temp you are doing more damage than good, in the long run.

I thought it starts with all open then goes back to closed. So glad i live in socal. Cant stand the cold!!

Legions, Sammy?

"A demon is a supernatural, often malevolent being prevalent in religion, occultism, literature, and folklore. The original Greek word daimon does not carry the negative connotation initially understood by implementation of the Koine ***948;***945;***953;***956;***972;***957;***953;* **959;***957; [Bimmerfrest won't display the characters....possibly they carry an occult charge] (daimonion),[1] and later ascribed to any cognate words sharing the root.

In Ancient Near Eastern religions as well as in the Abrahamic traditions, including ancient and medieval Christian demonology, a demon is considered an unclean spirit, more specifically an evil angel, which may cause demonic possession, calling for an exorcism. In Western occultism and Renaissance magic, which grew out of an amalgamation of Greco-Roman magic, Jewish demonology, and Christian tradition,[2] a demon is a spiritual entity that may be conjured and controlled."


Careful!

I think this is to warm up the catalytic converter faster.

Catalytic converters are modern cars are as close to the exhaust headers as possible; this eliminates you needing to 'warm up the car' before driving off.

Great Scot, man!

Don't believe everything you read....it's well known that divisions of the Roman [Italian] Army do not and have not gathered in BMW's.

Just opening up this thread again to ask related question about turbo 'warm up'.
Some one here mentioned that f30 will limit turbo boost when oil is not warm enough. True?
I noticed any oil temp starts moving after about 10-15 mins of driving and it gets up to 200 degrees after about 18-20 mins or so... So my question is, I try to keep my car rpm below 3k first 5-10mins then below 4k until oil temp goes up to around 200 degrees then I feel like I can floor it... Well is it safe to step on it a little bit more even when oil temp is below 200? Will turbo be damaged or warn out more if not warmed up? At what temp is turbo warmed up?

Sorry for so many questions! Appreciate if anyone can share your thoughts on this. My commutes are pretty short so don't get to easy the car unless I just go out for a joy ride. Hoping I can enjoy during my regular commutes.

Funny this topic came up. I was just about to post my own when, I saw this.

IMHO: I would wait until the needle stabilizes 180, 2000 whatever it is.

Now to completely highjack this thread.
I have a short 10 mile drive to work. The first 2 miles are through the neighborhood at slow speeds then, I hit the highway to work for 8 miles. On all my other cars, they're warmed up before I make the turn onto the highway. On the N20, I'm still sitting at 160 when I'm 8 miles down the road.

I was beginning to think I had a defective thermostat but, from reading this post it may be normal. Are others noticing the same thing? Slow warm-up?

Yep, mine takes 10-12 miles at highway speed to get the oil fully warmed up. I'm pretty sure the coolant gets up to temp much sooner, so I've never worried about it.

I did ask the dealer about the slow warmup and they (as usual) say it's normal.

Your other cars probably have coolant temperature gauges, where the F30 is oil temp.

Coolant warms much faster than oil and coolant temp gauges accordingly register faster. The reverse is also true; coolant will be at a lower temperature before the oil cools.

Haha, not highjacking the thread, just making it broad. My question is similar to yours. Since the temp goes up so slowly, I'm wondering if I can enjoy the short commutes. I just wait until temp is hight enough.
Mine just takes 10-15 mins to get up there. If my friends wants to go for a ride to show off the car, I can't do it because I gotta tell him we need to wait 10-15 mins of driving. Never can do short drive. I try to make my short drives long because of this reason.

Yes. The exhaust that isn't coming out of the other tailpipe is helping warm up the cats. You'll notice a lot of exhaust coming from the one that's open one until the flap opens.

Remember folks, the most efficient way of warming up your car is NOT let it sit and idle. Get in the car and drive off. This will warm the car up(Tires,Diff,Transmission,Fluids,Cats) all at the same time. Get in the car, let the RPM's drop(30 seconds to 1 minute) and drive off. I went over this exact topic with a Client earlier this week. Optimal conditions are achieved more quickly by doing this.

That's good info. Then how long do you drive until it's warmed up? When should I step on it little bit more and when can I floor it?

For the first 10-15 minutes, keep it under 4,000 rpm until the engine gets to operating temperature. After that you can gradually start opening her up.

Alright, that's what I TRY to do. This confirms what I'm doing is appropriate. Appreciate it!
