One more thing has anyone had this one happen. I'm driving for about a hour in at 120-130 mph for about 45 minutes. Car starts stalling like it's not getting enough gas or enough air. pull to the side of the road. Turn off the engine. Thinking great I'm in the middle of spain wonder how roadside works in the middle of no wear in spain. I turn over the car and see if it resets it self and it does. No other problems. Crazy huh?

Hey Brian, I have been getting the same hesitation as well, it usually happens earlier after I have just started the car and am driving, but today it happened at almost every light and stopsign. I have to push the throttle a little more to get it past the hesitation, and then it jumps out too fast once it tips in. The person next to me then thinks that I am trying to show off, but what do I care? I have thought this might be attributable to using 89 octane fuel and ethanol mix fuels, as this happens sporadically. I will mix in a 91 octane tank with every two 89 octane, but I am not sure if this is affecting the hesitation or not as I have not monitored it - but just simply assumed.

Thanks for any imput on the 1st section.

I felt it too and I think I am going to reset the transmission...however, the car is a lot more responsive in the sport mode...I didnt really notice the gas needle while I went cruising at 120...lol!

So, this is a weird question...after getting the dealer change my brakes (front and rear) + sensors I got rid of the hissing noise...however, today while I was braking, this was at a speed of 80mph...and changing lanes at the same time I felt as it the front of the car went slight right and then came back straight.. as if the wheels turned right and then got back to the straight position (I did not turn the steering though....)..I felt it was weird....anyone has any thoughts as to what it might be?

No offense but why would you even bother using 89? When bmw recommends nothing less than 91... Theres obvioslly a very good reason behind using 91, and 89.. such as engine knock, loss of power, lack of mpg and so forth. Hesitation... maybe related. Seems like the civic drivers dont mind using 91+ octane, but bmw 6 series drivers want to using 89- ... haha go figure

Put your money where the mouth is....premium is recommended...I dont compromise on that......hesitation is still there but never very noticeable....I would recommend you dont mix....its funny I met a guy who drives a Cayenne Turbo and he told me that he mixes 89 & 91....I didnt end up buying the tubo from him....

Mein Auto: 2008 BMW 650i Convertible
I just got my 650i convertible a few days ago so I'm NO expert yet, but I think I recognise the 'lag'. What I am surprised by is that there is some debate about sport mode - I notice an immediate and VERY VERY noticable difference when I press the sport mode button. i.e. it will change down immediately, and clearly changes down more quickly - the responsiveness is night and day different. I'll try the procedure to put the transmission back into learning mode when I'm a little more used to it the car so I can tell if there's a difference.

I too notice a huge difference in sport mode. I have a 6 spd manual transmission so I don't see the lag. You can tell however when the car hits the magic 3400 RPM.

Thumbs up The BMW 650i Tranny Reset for better acceleration

I have to say that this blog is the best I have ever encountered for information on my BMW.
I had a great running 2008 BMW 650i convertible with 23000 miles on it. I brought the car in to an auto body shop to have a minor scratch on rear bumper fixed. They disconnected my battery for some reason and I didn't think anything of it until I was driving my car home from the shop and noticed a hesitation in acceleration when the gas pedal was depressed rapidly.
I had never had that problem before. I was going crazy. It didn't happen in Sport mode only regular drive. Then I googled the problem and got this site. Bmmerfest had a guy tbal69 who had a do it yourself tranny reset that was easy and self explanatory. I immediately went out to the garage and tried it. I have a push button, so I put the key in the ignition, pressed the start button twice to get to acc mode, then pressed the accelerator to the floor for 45 seconds to a minute. Don't step on the brake pedal. Then I stepped on brake pedal, started the car and off I went. Holy ****! The car was back to normal. Fast and responsive, I had it up to a hundred from a dead stop, it kicked down and took off. I tried dead stop to acceleration several times and the car rode amazing. Thanks to TBAL69 and this site.

Wow had a lag/ jerk on initial launch, which thought it was normal. My transmission felt like it had a shift kit installed but without the good results. I did this "Tranny Reset" as soon as i got out from work and my transmission felt smooth right away..... Thanks for the info Guys!

Ok, folks, the reset is so simple it's almost funny. Go to youtube and look up BMW E60 transmission reset. A 30 second video shows that (without your foot on the brake), you move the key to the start position, then move it all the way to start. An icon appears on your function screen of a foot on an accelerator. When the icon appears, press accelerator all the way to the floor. When the icon disappears, your tranny is reset. Simple? Hope this helps you folks out there with the balky transmissions!

Transmission Reset 650i

The only problem with the key turning and pic of foot on accelerator video is that a BMW 650i has a push button start. But the concept is the same. Press button twice put foot down for 30 seconds and sometimes you hear a click sometimes you don't but it still resets.

I didn't see any posts here regarding the tranny reset that mentioned the icon on the dash or the fact that you have to turn the key to full start to get the icon to come on. My sixer is now running like a dream again.

What kind of car do you have that the key turns?

I was wondering what car you have that you can turn the key or is there a way to do it on a 650i with a push button?

Andy, I've heard you can press the start button twice...or do you have a key too? In any case, I'm sure you can bring the "foot on gas" icon up if you just perform the functions you usually would without the brake pedal. If you have a key too, push it all the way through "start" without your foot on the brake. Then watch your function screen for a "foot icon". Push it down past kickdown and wait for the icon to change to your regular screen. The job is done. If you have only a button push it twice without the brake like you were going to actually start it, and watch for the icon. Good luck and let me know if it works for you.
