Stupid questions thread--

[Robz26]

I'll start off with some of my own, but feel free to add yours.

1) DCT: Shifting into Neutral when in motion -- I've noticed I can put the car into Neutral when I'm in motion. Can you get back into gear while the car is moving if you push the brake pedal in far enough? Or do you need to come to a complete stop? If you do, isn't that a potentially dangerous situation if someone hits the shift knob while you're on the highway?

2) High revs -- what would be the impact if you continuously drove with the engine revved real high (7k+)? Would there be any near-term wear and tear? What about long-term? Do you just burn a lot of motor oil?

1. No, the DCT M3 does not support getting back into gear while moving, even a little bit. It annoyed me too when I tested it. The new 991 GT3 will though, one of its new trick features to replicate a clutch dump from an MT to initiate a drift. (EDIT: It seems I may be incorrect about this per some followup posts).

2. Cruising in the yellow zone would be highly inadvisable. Wear and tear is a product of using any engine, and it's simple physics that the harder you run it, the faster things will wear. All you'd be doing is wearing out your engine unnecessarily quickly and burning more gas and oil than necessary for the speed you're traveling. Why would you even contemplate that? I guess you at least got the thread title right....

1. I'm not sure why you'd coast in Neutral, but when you do, there's no need to apply the brakes to get back in gear. Simply move the gear selector back towards the D/S position and it will return you to the gear you were previously in.

2. No, drive this car like you hate it and it will reward you with countless smiles induced by high revs. The motor was designed to take it, and if you aren't bringing her up to 8,400 rpm, you're missing out on all the power, sound and fun!

Enjoy!

I have one: how many of you have drifted like this in public? (Accidentally or on purpose)

That's incorrect. The DCT is fully capable of going from gear, to neutral, and back into gear while in motion and without using the break. Do you honestly think BMW/Getrag would release a transmission that locks you into neutral while moving? Can you say "lawsuit"?


As to the OP's second question, I obviously misunderstood the question when I replied because it's such a silly thing to do. No idea why anyone would HOLD their rpm at 7k+ and let it sit there, but obviously thats not advisable!

Totally agree

The question is not as silly as it may seem:

Let's say you are living in Germany and have removed the top speed limiter on your car. You could be cruising on the autobahn near top speed with the RPM pegged over 7k RPM in 6th gear (6MT) for extended periods.

In my opinion the engine is designed to take it. But yes, it will suffer accelerated wear and tear when operating at high load and RPM for extended periods.

How many cylinders are in our v8? So fast seems like a lot.

Yes sir, I fully agree with your statement regarding sustained high speed/rpm on the Autobahn, and that scenario certainly crossed my mind before replying. That being said, I noticed the OP is in New York, so needless to say, he will never find himself in said scenario. The wording of his question led me to picture the OP humming along in 3rd gear at 7k whilst cruising at 60mph on a highway lol...

Lol, this is actually a problem with teflon

Hmm, interesting about DCT shifting from Neutral while moving, it seems I stand corrected. Maybe the DCT I test drove had different software? When I made a 3-point turn on a hill during a test drive and started coasting down the hill in Neutral, I got the "Apply brake" icon on the dash when I tried to put it in gear. Admittedly I didn't try shifting while holding the brake and merely slowing down rather than being fully stopped though, maybe that was it? Although I can't see why it would allow you to shift into gear while braking but not while simply coasting... Glad it was corrected if I was wrong, though.

As for the autobahn scenario, that might be part of why the limiter is there. I know about the 155 MPH gentlemen's agreement in Germany, but tire ratings and gearing could be in play as well. A 6MT in sixth with 19s would hit 155 around 6800 RPM; at 7K it would be doing 158 and at redline it would be doing 189. So maybe BMW set up their gearing so that the 155 MPH limiter was reached in top gear at an engine speed they felt the engine could safely cruise at, in which case removing the limiter would have you cruising at a higher RPM than BMW intended or would recommend? Whatever the case, even if the engine can safely handle cruising at 7K or above without grenading, I still wouldn't do it on a regular basis. And fyi the fact that it might safely cruise at those RPMs in higher gears doesn't make it safe to do in lower gears since there's a lot more air coming into the engine in higher gears.

I'm picking up what your laying down. How far to the east do you have to go before your in the west? Why does the doctor leave the room while you undress?

[iron_man]

on my idrive where you check your oil level i only have 3 bars and inbetween my tachometer and speedometer where you can change those cool settings (speed, mpg, oil level) my oil level is right at the middle line. When I got my oil changed it was to the top. Do i need to top off my oil? I brought in my car to the stealership and he gave me this look...

and replied with that's normal and unless my car gets to the 1 bar then i should bring it in to get topped off because that means there is only 1 quart left of oil...

So I did this...


and proceeded to come on here and make a thread about it asking you guys what to do because i feel he had no idea what he was talking about, but then i saw this thread and decided to post it here.. so do i need to add oil or not?

Where the F is the date on the idrive screen? My 07 335i had the older idrive and it told me today's date at the bottom. But cant seem to find it in the newer idrive.

Maybe canuck cars are different. Gotta put a bit of pressure on the brake pedal to shift back to gear in my car. It doesn't take much brake though.

Read this thread earlier so when I was leaving the office I tried it out. Started to drive in first, put the car in neutral then popped it right back into first, no brake application required. Granted I was going slowly in my parking garage so not sure if my low speed impacted how the car allowed the shift. My car is a 9/10 build but had the software updated about a year ago...
