Drove 09 DCT

Ilyam5 · 10-13-2008, 07:40 AM

Stopped by the dealer on sunday and they had an 09 DCT coupe. Went for a longinsh test drive and wanted to test the DCT known issues.

Glad to report - the car felt perfect. No lag on upshifts, no hesitation. Did not stall on me

Also tried several on ramp entries from about 80 and hard braking - no problem - willl downshift from 4-3 and from 3-2 under hard braking. Wasn't quite track simulation since i was on public roads but felt great.

I had a novice student in an 08 with DCT and the downshift problem was quite obvious in his car.

Also new navigation is great.

guess the car you test drove already had 1200 mile service? somehow...

thought DCTs had low rev limit before broken in all the way....

so if you couldn't get to 8k+ rpms to test the downshifts... then how do u know the prob is fixd?

No rev limit at 4K on the car. It's a myth - the same as manual. The car can be revved and has the same power at 0 miles.(most cars and BMW Performace center have less 1200 miles and are driven hard ) The only thing missing on the DCT is Lauch control.. available after 1200 mile service. Other wise - no difference.

Downshiting problem did not occure at redline. It happened at threashold braking.

Ilyam, so to be specific, you were able to floor the car in first gear and pull the paddle at 8K+ and you did not bump the limiter?

You are getting a bit too specific

I was mostly interested in the downshifting problem, since that is the base for my buying decission. I will be using the car on the track.
I drove in the e46M3 SMG and switched to e92 all within 5 minutes and the difference in immediacy of shifts was not noticable between 2 cars - hence my comment on no lag.

I accelerated hard from 1st and second gears out of the ramps and stop signs and switched when the lights approached red (just like SMG).. I tryed S5, S4, S3 and I believe i was in the visinity of 8K RPM. If i go again I'll test specifivally for this issue.

Ok. I was just trying to compare because footie said he was able to do that in his car post-update. So I was hoping to get some confirmation that the '09 cars are behaving the same way as the updated '08s (i.e the software is the same).

If it wasn't for the fact that to show this on YOUTUBE could possibly lead to the police at my door I would video it and post it for you all to see.

It's dead easy to flick the paddle at over 8k and shift before the limiter is hit, a child could do it now. Just wait and see when your car gets the update.

There is no rev limit during break-in... total Forum DCT BS

I over revved mine to over 7K+ with only 700mi

+1

yup, very easy to go over 5500 rpms during break in.

footie · 10-13-2008, 03:16 PM

There is no actual limit in revving high than 5500rpm. But doing so is not recommended, both in the manual and on your window sticker.

But like everyone here with an M3 I too have accidentally when over the break-in limit on at least 5 times, one as much as 7k when I thought I was in D mode and was in S mode instead.
