2016 340i shake during start-up

zeddladd · 10-22-2019, 11:12 AM

Cold startups in the morning there is a noticeable shaking - smooths out after 10-15 seconds. Any thoughts?

Mine does it since Day 1. BMW service advisor told that it's normal.

My 340 does not do that, our 335 did not do that and my Sons 328 same story nothing...(heck my BMW diesel didn't either) - that said if it's by chance ambient temp related I'll point out that I'm in SoCal.

I have the same issue but also have a feeling that my car is about to cut out. When idling there has been a few occasion where it drops in revs and then picks itself back up as if it's about to cut out. I have had the car for about 2 weeks and is only at 9300 miles. The car at that sort of mileage should not have any issues.

May occur just after cold start if you throw it in gear right away in comfort mode. Shouldn't happen in sport or sport plus.

Happens to me. I think it's an issue with the A/F mixture sometimes but mines tuned so I don't know. I give her a few revs and she's fine
