Has anyone tried Launch Control on a 335i DCT?

Hi,
As the title says has any tried the launch control function on the 335i? Does it function before the run in period of 1250 miles is covered. Tried it tonight but I can't get the Flag symbol to appear once the accelerator is fully depressed.

Help appreciated.

Dougie.

are you guys simply talking about where you hold the DTC button down for a half of a second vs turning it all the way off. I cant remember exactly what is says.

IIRC on the M5, the LC wouldn't work until the car was brought it for its 1200 mile service and the dealer activated it.

I have Launch control on my '08 GTI DSG and have never used it. I just don't feel the need to thrash my transmission, tires and engine that way. Maybe I'm getting old, no I AM OLD according to my 8 year old daughter. This whole Launch Control frenzy happened 2 years ago on the VW/Audi forums when it first came out. After trying it once or twice just to see if the car is capable of doing it, most people don't even use it anymore since the novelty wears off quickly.

Truth is, although VW/Audi pioneered DSG (DCT in BMW speak) it is still not quite as smooth as the steptronic in my '08 335i. Honestly, the 335i step shifts faster UNLESS you are in sport mode in the DSG (DCT). The DSG is touted as shifting very fast however it has different shift modes and in routine normal driving there is a definite delay in shifting manually. However, when you are in sport mode the shifting is very fast. Most don't drive in sport mode all day long since it also holds shifting til near redline.

I tried it once, it pretty impressive. you have to press DSC once, to get DTC. Put the gear lever in S and use the steering wheel pedals to put it in M1, push the sports button. Push the accelerator pedal all the way in, over the pressure (down shift) point. You will see the flag symbole. Lift of the break and hit the gas.

You can also find it in the manual!

you can only use it after 10km drive, after you have used it you will have to drive 10km again.

I've used it for several times now, even two times today. One of which my friend did it, and got caught by the police They don't seem to like the smell of burning rubber in the Netherlands heheh..

He got off with a fine of 150 euro's (around 180 dollars) for causing too much noise. Usually a burnout means an "article 5 offence" in the nederlands, and will cost you you're drivers license for a couple of days (or months if it isn't the first time). But this officer was polite, lucky us!

Anyway, it's quite simple. As the post above mine said:

- Hold the DTC button for about 10 seconds pressed (traction control (DSC) is now completely off)
- Push the gear lever to the left and pull it down once to put the gearbox in M1
- Also push the sport button onder the gear lever once
- Push the brake pedal with your left foot and hold it there
- With your right foot, you push your acceleration pedal to the floor (using kickdown) and wait until rpm is around 2,5k
- At least, lift your left foot from the brake pedal and off you go

By the way: some people say the're getting a finish flag symbol, but I dont.

Today I discovered there is a "shortcut" to get launched! Because it's an automatic gearbox, you always brake when you're waiting for a traffic light. Now when you hold your brake:

- Push the gearlever to the left en pull it down again to get it in M1
- Let go of the brake with your right foot and push the acceleration pedal as soon and fast as you can to the floor (again kickdown) with again your right foot.

The car will rev up very fast and the clutch will come in when you're about 6k rpm. It's the same thing when using launch control, except you don't have to hold down the gas and the brake at the same time.

Only this afternoon the gearbox went automatically into Drive while launching, probably some kind of a protection for damaging the gearbox or clutch. I've told there are several built-in sensors and protections to keep you from frying your gearbox. Probably this was one of them.

PS: launch control will only work if you've driven around 10km (or 6 miles) to get your gearbox warmed up!

I had launch control on my boosted miata through megasquirt. Launch control is one of the best things ever, but it does get kinda old after a while. The best thing they should bring is Flat shifting. Its a godsend for not losing revs on a turbo'd car
