Various Questions on my 2014 535d

A grabbag of questions on my 2014 535d:


1. If I have been shifting manually and the shift lever is in M/S, is there any shortcut out of manual mode without having to move the shifter back to D first?

2. Does anybody really understand how the Mode button affects the Sport Auto transmission? AFAIK, it has no effect whatsoever. The faster shifts and the higher shift points are a function of where the shifter is placed. What am I missing?

3. Is there any way to adjust the sensitivity of the auto headlights without recoding or going to the dealer?

4. My steering wheel is about 5 degrees to the left. It was delivered this way and I know it's not the crown in the road. I'm curious if anyone else had the same thing. I'm bracing for the inevitable fight with the servicing dealer.

5. I have a Samsung Galaxy S3. Is there any conceivable advantage to the BMW Snap In Adapter, as far as audio integration is concerned?

Thank you!

#1 and #3: No
#4 - simply request the dealer to center the steering wheel. There should not be an argument. Don't always prepare for the worst, IMO.

You should definitely notice that when you change the Mode to Sport, the tranny will usually downshift and hold higher revs before upshifting. I can't really tell if the shifts themselves are milliseconds faster, but you'll definitely notice you're in lower gears with more ready power.

Just experiment with the shifter and mode on your drive, changing them up to see what happens.

I will usually see that changing mode to Sport makes a downshift, then if I put the shifter in M/S it'll make another downshift. But not often the reverse. ie in Comfort mode, put shifter in M/S makes a downshift, then change to Sport mode usually won't make another downshift. But Sport mode gets you the faster throttle response which I like.

I have tried and cannot figure it out.

A shifter move from D to S definitely results in a downshift. A move from Comfort to Sport almost never does, and when it does, I think it's just throttle remapping that causes it. If I'm in D, a change from Comfort to Sport results in no discernible difference.

Robert-

I recently took delivery of a 528 in Munich at the Welt and asked the delivery specialist the same question. Her answer was an emphatic "NO" (with head shaking) when asked if the DDC switch affects the transmission. That's consistent w/ my experience with the car so far as well, and makes logical sense. Your theory about how the throttle remapping might sometimes cause a downshift when switching to the sport mode also makes a lot of sense.

Mine 8AT(without SAT) does downshift when changed from Comfort to Sport dependent on the rpm. For sure Sport up-shifts at higher rpm than Comfort.

But can you be sure the delayed upshifts aren't caused by more aggressive throttle mapping?

My layman understanding is that the drive modes affect throttle mapping while the shifter position controls the transmission shift responses. 6MT surely looks easy doesn't it?

Then I'm a little confused by your conclusion. I thought you said previously that shifts points were affected by the mode switch.

Yes, 6MT is much simpler and more direct.

When I put my car in sport mode with the button, I get an almost violent boost but I prefer to just jam the gear lever to the left where the reaction is more smooth and seamless.

It is more an observation than a conclusion. The shift points are noticeably higher while in Sport than in Comfort, and my guess is those are part of the computer mapping per mode. The M/S position itself also affects the shift points, but does not seem to be as aggressive as Sport mode(may need to experiment again to confirm). BTW previous F30 posts did comment that sports auto M/S holds at redline without up-shift and does not downshift at kickdown.

Life would be simpler if the gear shift had just two positions -- Drive and Manual. Then the mode switch could control the shift points, and we could just leave it at that.

Initially it was fun playing with the different permutations, but it got old after a while(and there is no last-user mode!). These days my driving is mostly Comfort or Sport in D, and infrequent M/S manual shifts.

OK, some observations(on F30 N26 8AT without SAT) on the short drive back home:

1. at constant 40mph, changing from comfort to sport bumps the rpm from 1.5k to 2k.
2. at constant 40mph, while in sport mode, changing from D to M/S(no manual) bumps the rpm from 2k to 2.8k. Going back and forth between D and M/S causes the rpm to change between 2k and 2.8k
(haven't tried comfort mode D and M/S back and forth, my guess is similar to #2 but lower rpm)

So it looks like comfort to sport is one downshift, and D to M/S is one additional downshift. F10 8AT probably should behave similarly.

I think you can call it what you want, but if you place your car into Sport, the transmission will downshift a gear and hold the gears longer then in comfort and Eco-Pro. That is why it is called "Sport" and "Comfort".

Well, don't forget that the mode switch controls steering effort, throttle mapping and damping (if so equpped) so there's more to it than transmission shift points (if it even affects those)

I wasn't going to confuse the OP more then what they are.

Stepping on the gas also causes delayed up shifts. The revised throttle mapping may be doing the same thing.

It doesn't confuse me. I understand these factors as well.

One observation is, if shifter is in M/S position(left), switching among /Eco/Comfort/Sport does not change the shift points, e.g. at 40mph, all modes are at, say, 2.2krpm, provided it is constant cruising at 40mph. However, if the engine is under load(e.g. slightly accelerating and/or uphill), switching from comfort to sport(with shifter at M/S mode) would still bump rpm from 2k to 2.8k. Having said that, Comfort to Sport seems to bump up the rpm in D most of time even when constant cruising.

If I recall correctly, putting the transmission in sport mode delays upshifts, but also locks out 8th gear, so if you enter it above 50 mph or so, you will automatically downshift to 7th, hence the rpm jump.

When you put the transmission in Sport mode (and by this I assume you refer to moving the lever to the left), it clearly does this. The question is, how does the Driving Dynamics Control (DDC) affect the transmission? What's the interplay between the DDC and the shift lever?
