DCT shifting to Neutral by itself?! - BMW 3-Series (E90 E92) Forum

33Five-WA · 11-16-2012, 01:54 AM

Not sure if this topic has been discussed and my apologies if it has.

Has anyone with a DCT tranny experienced the gear shifting itself to Neutral when the car is running cold? I've had a few occurrences when I'm waiting at the lights on the way to work and the idle drops to under 600rpm and the gear shifts itself to Neutral - like a safety mechanism? Then it revs up high to about 1000rpm and drops back down to idle range @ 660rpm.

Also, I'm not sure if this has got anything to do with it and the few times it has happened is when the car is in a bit of an incline? Weird. Not to mention the car next to me thinks I'm going to hit it at the lights!

What car is it? I have only ever seen it once where there is something to do with the door lock and the seatbelt buckle.

Oh OK. Could get a bit dangerous in intersections or turning out of a corner etc. Guess I'll just have to leave to warm up a bit more prior to driving out.

Well in 40k's this has never happened to me.

Neither to me either.

Ask you stealer or an indy with Autologic to do a software upgrade, we did one with similar issues and so far it has been fine.

jp330Cic.au · 11-18-2012, 01:18 AM

happened only once to me. I really didn't like the feeling; when you want it to be in D for drive, you want to be able to put your foot down and it should go.

I don't think that it is normal at all.

Thanks skycat

mine does it so often it has become normal to me, clearly it's not normal ! Will get SBM to do a software upgrade next service.

Thanks for the feedback guys. Will look into it. Cheers!

Scootah · 01-28-2013, 08:15 PM

So , following advice from Skycat , had my DCT trans software updated and a couple of weeks later no shifting to neutral (touch wood)

Work done at Southern BM , again Andrew is a legend

This has happened to me numerous times, I also experienced like a jerking movement when rolling forward with the slightest throttle

, took the car to BMW and I was told that the " software" was replaced. The car hasn't done it since but at idle cold or warm it revs higher round the 1000-1200 mark.
