I'm sure that most people on the forum know this since they are generally enthusiasts but I've bumped into several BMW drivers that had no clue about "the other side" of their auto stick. They were almost scared of it. This is particularly true of the spouses of enthusiast drivers who don't drive the cars very much and are just happy to leave it in D like all other autos they've driven.

I've seen some posts here like "I drove home for 10 miles in DS mode - is my engine okay?". This was just a couple of weeks back. Yeah, here it is: http://forums.e60.net/index.php?showtopic=18860.

I believe E, XE and S, XS modes have been eliminated starting with version 19.01 of the software. We are back to D and S only. That's how my E39 stptronic used to work and that is how my 2005 545 behaves after it was upgraded to 19.01.

S = DS on my US 545i with 19.01.01.

This is what i did to reach the ~9sec 0-100km/h mark on my 525d with Steptronic (in DS mode but kept DSC on).

One think that keeps puzzeling me is the consumption... i can't get it lower than 8,6L/100km. I drive in either save mode or full burn mode. I have won a low-consumption competition a few years ago, so i know (or should know) how to do it, at least in a non steptronic car.

The main cause i am finding for this is that the gearbox is always in "slip" mode so the engine revs too much. I read the docs about the box (in vnod threads and others) where they say it should not slip when not required.

Are your Steptronic always "slipping" (i.e. when you accelerate it revs more that required for the current gear/speed)?
Can my Steptronic box have a problem?

Thanks!

I think "slipping" is cause by a worn torque converter. The cause is frequent hard accceleration. I have not experience "slipping" yet; I don't intend to do lots of hard acceleration either.

I did not see anyone mention "Sport" D. Separate mode than DS. Leave shift lever in D and depress "Sport" button. This has same gear action as DS (1 - 5) but also increases throttle tip in as I understand it. Probably discussed in one of the reference threads, sorry I did not go to look befrore responding. I retested mine up to 125 mph and neither "Sport" D or DS would shift out of 5th into 6th. I need more space to take up to higher speed test on this.

Where is my "Sport" button?

Uh oh, the 545 Step does not have that? Sorry, I would have sworn I saw discussions in various threads about 5 series owners using that Sport button on a Step tranny. My button is just rear of the shift lever. My apologies for letting the cat out of the bag for the 6er Step tranny/Dynamic Driving Control combo.

OK...

I tried once again and these are my conclusions.
By the way, today I was driving 645i


Sport button is below the gear stick (I don't have it but BMW 645i does)...I think this button is for suspension...I didn't notice any difference.

When driving in DS it change to 6th gear at 150 - 160km/h. When driving manual from 75km/h and in D mode at 85-90 depending on acceleration pedal.

About shifting in my E60 and 645i... i think there is no difference (diferent speed,better brakes,...)

I recognise something new... traction is a little different when driving DS... let me explain... it seems to me that DSC or DTC begins to work a little late. not secnds but just a feeling...on the corners I can feel the car beeing not so stable (like my back is dancing a little). I tried at 100km/h(cruise control) and go in D , DS and M4. In Ds an M4 the back of the car was nor stable. Then I tried a little different way. No cruise control,, exactly 3000RPM and then release the pedal and go. I notice that at the end in D mode I have a little less speed. I tried these for several times and always the same... When DSC or DTC is enabled in the curve (in the middle of driving), the end speed is always hihher when I have in M or DS.


Ok . Enough from me. I'm realy happy to discover DS. My life with steptronic is even better.

Thanks guys!

Hi,

My car has only got 27.000km/h...
Has anyone "seen" or used a worn torque converter? Or know anyone that has had this problem?
It is only a 525d... if the same gearbox is used in the 535d, i imagine it must be very resistant... no?

Thanks!
