I have a new 230i just 500 miles. Sometimes when i stop at red light i feel engine shaking through my seat, and i can feel it pump up and down in my butt. It happens even when i drive more than 30 mins, and i stop with engine still working, even passengers can feel it.
Im always start engine before at lease 3-15 mins since i got a car

However, sometimes when i stop idling it feels nothing, very quiet, no shaking, nothing ... Like my last C300.

So i wonder Is that shaking normal or not on BMW ?

It’s not normal. You have a warranty, take it to the dealer and hope they can reproduce it.

Update: i drived more than 40 mins in city today, engine was smooth every single time i stopped. It hard to go dealer and tell them what was happend. Anyone have the same problem with new car like me ?

Low quality fuel or moisture in the gas? Put some fresh 93 in it from a different station see if it comes back again.

My new (May 31) 230i doesn't do that.

Mostly I use Sport mode which disables the auto stop/start feature. I tried Eco mode the other day with auto stop/start active and the engine started up with a bit of a shake. But it was short lived.

There is a button just in front of the engine start/stop button to disable the engine auto stop/start feature. Disable that feature and see if that's what you are feeling.

CTGT2005 may be on to something regarding gasoline.

Be sure you fill up with the right octane of gasoline. Buy from a busy station to ensure you get the freshest gasoline. Try another brand, a name brand. Shell is good. I'd use it here where I live but all the Shell stations have 91 V-Power around a $1 more per gallon that 91 at other stations. Insane.

But thankfully the 230i is quite happy with the 91 (ethanol free) I get at a Littlefield Express gas station or 91 (E10) I get at Casey's or the occasional fill up at a Philips 66 station.

My M-B cargo van engine likes the same gasoline as did my previous Dodge Challenger Scat Pack engine and my Hellcat's engine before the Scat Pack.

I have 4,000 miles on my 230i and have fueled it with nothing but top-tier 93 or better however, I have experienced what you are describing.

Even with stop-start deactivated, every once in a while, when idling or at a traffic light, the engine stutters like it is misfiring.

It does not do it consistently: most days the engine does not stutter, sometimes it will "misfire" a few times in a row, even when the engine is warm. One time the car stalled on me when it was cold and I was moving it for the first time that day.

I have not had the car to the dealer for diagnostics as I don't think they'll be able to reproduce the issue. It's not consistent and does not happen very often. The onboard computers have not reported any issues.

if anything more comes of it I'll make another post.

Im always fill 93 in costco (and costco only has 87 and 93) i just filled 2 times for this car and i remember the price. It is 68$ for 10.8 galon, so can not wrong for 87 cause it would cost much cheaper.

Today is 2nd days it was ok, no more vibrant/shaking in 30mins driving. I just remember it was shaking/vibrant likes when i push turn off engine, but it shaking all the time i park idiling.

Yes, i feel the same, i think it just because engine not warm enough, nothing show up on dashboard too and thats why i think it normal, but still need to ask u guys to make sure is that ok. I always pump 93 too.
Today it was fine, nothing wrong happen, no more shaking. Hope this is just a new car need more time to run everything smoolthy and not a real problem.
