DCT Automatic mode question
This is my first BMW. It's a new to me 2008 M3 Convertible with DCT. Had the car a few days now, I've been driving mostly in manual mode with paddles.
Today, I decided to try driving in auto mode (drive logic set to 1) and notice that it shift into 7th gear at around 50 Km/Hr or 30 miles/hr. Is this normal ? I always thought we should be around 4th or 5th gear at this speed. It's driving fine at 7th gear. I am just curious if this is normal. Thanks |

Ya it's normal.. It's in drive logic 1 the pussiest of them all. Try a higher setting and you'll be at a higher RPM and lower gear. I think there's a way to reset the memory of the gear box to re-learn your driving style, considering there was a previous owner.

D1 starts in 2nd gear I believe and should only be used in snow type conditions.
Even using drivelogic at the most aggresive setting D5 you will still find it will go to 5th gear once you get to around 65km Last edited by G.R; 10-15-2010 at 03:15 AM.. |

Since my M3 is my daily drive (2000miles/month) I am mostly on D mode. I started at D3 for a while, was too weak for my liking, then D4 which I enjoyed for sometime till I wanted more aggressiveness, then currently D5 that I like alot. It makes 2nd gear longer, 6gear is the top one untill you're cruising at same speed for a while then the car gets in 7th. And best of all the car is more responsive to down shifts and quick pick ups after cornering. A little less gas milage than before but who the he'll cares!

Question out of curiosity for you guys. When you are in Manual mode with the DCT and you are slowing down to come to a stop say at a stop light. Do you let the computer downshift or do you manually downshift using the paddles? Ive been doing both, just curious what others do.

There have been a hundred threads on this stuff, but my experience was:
D2 = 60 percent of the time D4 = 30 percent of the time S2 = 05 percent of the time D5 = 04 percent of the time (for reasons noted by others - holds gears longer) S4 = 01 percent of the time Let it downshift it's self about half the time in manual mode.

Still on the steptronic, but with this and when I test drove the DCT, I manually downshift pretty much the same as I would in a manual, using the engine to help slow the car a bit rather than the brakes. I drive about 99% in manual mode, felt more natural coming from manual vehicles, never got used to letting the car do it for me.

quick question.. when i am in manual mode (s mode) i am usually in s5.. and when i am coming to a stop like at a red light or something.. and lets say i am in 5th gear.. i usually downshift all the way down to 1st gear manually... now when i do this the car begins to shake and get really jerky and uncomfortable when slowing down.. mostly in starting from 2nd to 1st gear.. now is this because i am going to such a low gear and the car is revving too high? which is causing the jerkiness?.. is this bad for the car as in the clutch? or is this not normal and i should get it checked out?...

If you feel that way, I am curious why you use manual mode to begin with. Keep in mind, in manual mode, the car only downshifts to prevent a stall. It's really a minimalist way of downshifting IMHO, and is not the same as when it downshifts in D mode.
