engine "shaking" during startup
I don't really know how to explain it other than it feels like when I first start up the car it feels as if the engine is shaking or so for 3 seconds where I can feel it when sitting down. It feels like it's moving left to right for a few seconds and just stops. I recently put back my stock intake and it started happening. Anybody know what could be wrong? I am 99% sure everything is installed right tubes are all on tight and everything.

I had a similar problem and it turned out to be a bad starter motor. Covered under warranty thank god.

I have exactly the same problem..
Left the car at the local BMW service centre for a bunch of tests to diagnose the problem but they couldn't tell me why the car shook upon start up! Please let us know how you resolve it, thanks. |

happens to me. im not too worried. the car has made weird noises since i bought it but its never let me down.
especially after how the car makes that grinding sound during start up some times i just accept the fact that shaking is probably normal too. :/ w/e lol |

I had a similar problem and it turned out to be due to a missing rubber boot in the engine bay. Boot was replaced under warranty.

Have your knock adaptation reset...had this problem with my 330 and it helped abit...cleaning the MAF fixed it.
I reset mine with my BT Tool...if you don't have one, you'll probably have to have take it to a dealer. |

Another problem that can causes this is a sticking vanos solenoid.....I had code 2A98 being thrown in my car and I would get intermittent jerks (side to side) at start up.
If you know how, remove the solenoids and blow compressed air through them. You car will throw a code if it detects a sticking vanos solenoid.....2A98 and 2A99 I beleive. One is for intake other is for exhaust side. |

I would look into the suggestions said by other members in this post. My shaking went away after a day and never came back since so I don't know what the problem was.

Try starting the car with your AC off, as this was the culprit for me.

I have had the same problem for some time and I have now been informed there is a software update to correct this problem. I was notified by BMW about this and an appointment has been made for June 23rd to have the update done. The dealership that was working on mt car created a puma because they could not determine what was causing it. That is why I was contacted. I will see if I can find out more information specific to the update.

I took mine to the dealer. All they did was up the idle and said that the problem was gone. This morning when I start my car I'll check and see if it still shakes. Will keep you updated.
