I can assure you it has nothing to do with type of gas you are putting in the car. My new 2018 540i does the same thing. Shaking on cold start. Build date 1/1/18. Purchased 5/19/18. I have 2600 miles on it. I was on another forum and was told to use different gas and a different station. They were thinking water was in the gas.
I use Shell 93 octane always. My previous X5 did not do this and I used the same gas in it. I don't fill up at the same station all the time. So gas is not the issue.
I ended up taking the car in and my dealer did a software update on the whole car. He said it fixed the issue. Got it home. It did NOT fix the issue. Not sure where to go from here.
On another BMW forum site, there are people with this same problem. One guy has a build date of 12/17. He says that BMW knows of this issue but there is no fix as of yet.
Frustrated.
