Does it hurt the car to chronically drive in DS mode?
Just wondering whether constantly driving in DS mode will hurt the car. Any experiences? comments?

I don't think there is any problem driving in DS mode all the time. BMW has well design on thier steptronic gear box. I drive 90% of my time using DS mode with manual shift. The other 10% of the time I drove in D mode is when i was in a traffic jam. I drive the car just like driving a manual most of my time.

DS mode only hurts your wallet

Steven,
I think the question is, would it heart the gearbox, to keep on changing between DS and D while driving? I've researched on that adequately, and yet to find a convincing answer... |

Now if you mean whether driving in D and suddenly switching to DS will hurt the engine, I stick to the theory that a car which only uses 2-3k rpm on the street will eventually get slower and slower, because of the gunk built up inside the engine during low engine speeds (the turbo system has an exhaust air recirculation system, which ends up bringing in some of the impurities in the fuel to the intake side straight back into the engine... a catch can mod should help too). If the car gets exercise chronically, this gunk actually gets cleared out of the car's system via the exhaust pipes, and is healthier for it. As for gas prices and the extra burning of fuel... I agree with everything they said! LOL... |

This gunk is also called Carbon. BMW build a lot of carbon inside the engine compartment. Driving from time to time during 5 min above 5000rpm keeps the engine clean for the same reasons you mentioned.

Phawx: Tks for your input. If D & DS were only electronics switches and no mechanical switch is done... Why when you switch between both, you feel the gearbox is being mechanically switched? Wouldn't it be easier to make a button for the DS?
I think there is more to this than just a simple switch between 2 electronics pre-set programs???? |

http://www.realoem.com/bmw/showparts...36&hg=25&fg=20 I think I'd need further diagrams to be sure, but from what it shows here it looks as if the auto tranny is just a big switch with a wire connecting somewhere else. Someone correct me if I'm wrong! |
