Today I was driving home from work I stopped at a red light (happened twice), when I went to take off THE CAR DIDNT MOVE!!!! IT WAS LIKE THE CAR WAS IN NEUTRAL!!! WTF!!!??? It took about two seconds before it moved.
DOES ANYONE KNOW WHAT MAY HAVE CAUSED THIS?

You sure it wasnt in neutral

TRUST ME lol

if it was i should consider donating my car. I should also have my license revoked for life and shouldn't be allowed to ever drive again

I'd bet that it has more to do with an electrical glitch than the tranny itself. Impressive but not mechanical cause, IMO..

There's something called neutral idle control in our cars that will disengage our diffs when coming to a stop to increase gas mileage.

You should check on that.

I just woke up, and with this issue on my mind. you guys just made my day...

I did find it extremely weird, cause its shifts fine, really. And I thought about it and thought maybe it'll be a stuck valve in the valve body (if they even have valve body's, I wouldnt know cause I dont know anything about BMW), but then again, that'll cause problems shifting out of 1st (into 2nd), cause 1st is always engaged when in drive and stopped. But now that you're telling me it disconnects....? hmm would have to do my research

I agree
I had a dead battery 2 weeks ago and once I jumped it the car would not shift at all. BMW tech said that when the computer detects low voltage, it starts to shut down certain systems. The car will re route power until the voltage comes back up. After about 20 mins, I shut the car off and re-started it and all was fine. These cars have a way over the top electrical system. Every last thing is controlled by the computer. Makes the average guys mechanical skills useless.

I much rather buy a new battery than have to take my car in for service, especially for a trans. issue

Amen to that.

I had that issue until I got my Sprint Booster, then the BMS Powerbox, and now the AA tune

Stupid eletronic throttle bugs if you ask me. Happened to me a few times. Normal from factory, regretfully I'm afraid

Thanks, bud. Just did a little research, and yep, exactly what you said, it does. but why do you think it didnt engage first gear quick enough? (if the NIC is even the issue)

How much did this run you??

The Sprint Booster was my first attempt at ridding myself of this horrific trans lag "bug". That ran about 250 at the time. I sold that and went to the BMS powerbox, which is another piggyback module. Both of these improve throttle response, but do not do anything in regard to power gains that I have experienced.
The AA tune is AWESOME, and a true tune to the ECU. You can definitely feel the difference. It isn't like it'll be a turbo suddenly, but a nice increase for sure in all the ranges and off the line. I would prefer not to post prices for Active Autowerke's sake, but you can definitely PM Viral or Omar@ActiveAutowerke. They are vendors on this forum

BTW, you are RIGHT BY Active Autowerke, you lucky bastard! They are based in Miami Well worth a day trip, lots of nice cars

[3002 tii]

do you have AUTO or Manual?

Revs go up but car doesn't move... lag, and then car buckles/lurches forward? Sounds like your transmission is slipping.

How many miles on the car? Have you done any work on the trans, ie fluids?

Does this only happen when you're at a complete dead stop? Or does it happen when you're cruising and get back on the gas?

When is the last time you had service? Do you know of any software updates done to your car?

I think what you may have experienced is the sticky brake issue but it just lagged a bit. I think an update to your car may fix this.

yea I'm close!! as a matter of fact, we're gonna have a meet down at their place on March 12th :
i'll be asking someone about the tune when i go over there. thanks for the info franco

ehh, it did not move. it was twice that it happened, at a complete stop. Yesterday, first time this happens, it happened while it was rolling.
I was even getting ready to put my hazard lights on when I reached out for the button i noticed it moved. It feels like the transmission just disconnects. but when it connects its at a low rpm and i dont really feel the car buckling
car has 54K mls. Auto Trans. about the trans fluid, i read somewhere that the trans fluid is good for 100K mls. is this correct? at least I havent bothered looking into trans flush cause of that

excuse my ignorance, but i found out last week that these cars need software updates How many hours does a dealer charge for software?

Anytime pal! I think you'll LOVE it. It's not detectable by the dealer in 99 percent of cases, but it's not supported and COULD void the warranty for just the engine, ECU and related parts. Of course you would have to have a specific issue related to the engine ECU etc AND they would have to prove the tune caused it. The software update should be on the dealer's nickel I would think. In any case get the 'updates' before the tune if you decide to pull the trigger.

I'm out of warranty anyways

Then go for it. You won't regret it.

[3002 tii]

yes, "lifetime" fluids although if you plan on keeping the car, it wouldn't hurt to change it at one point. i'll probably change mine at 50k. reason i asked though is because if you did NOT use oem fluids, then i thought that may have been the culprit.

did you notice any burning smells during the past few weeks? if so, still think its your trans... if not, then probably a glitch like everyone else suggested.

Well dealers charge between $125-$150 per hour for labor.

A complete programming will usually take most of the day...4-5 hours I think.

You can try to find any indy that can do it. But that's going to be tough.

yea my local dealer charges $149, but FOUR TO FIVE HOURS?!?? My wallet is getting raped lol
I know about a shop nearby that does BMW work but I need to ask if they do this kinda work. Tough, cause I doubt software is easy to get its hands on, not like oem parts. Wouldn't it be sick if we can just download the software from the internet, hook up our typical, everyday, USB cable to our computer and go on with out day?
