Hello and welcome,
My name is ***** ***** it will be my pleasure to assist you today.
Do any warning lights come on when this happens? How violent is the lurching?

No. I did take it to the dealer last Thursday to get oil change and they said it's time for a brake flush. No engine or oil light is on
BMW Mechanic: Steve, BMW Expert replied 7 months ago

thanks. so your question, to clarify, is if it is safe to drive or not?

Is it safe to drive and what could be the cause. Onset was sudden. Only things to change were getting the oil changed. And I also filled the gas tank the day before

Please do not forget to click a positive rating as this is the only way I receive credit for my answer, thank you

I would strongly advise against driving like this. A) it isn't terribly safe if the car is lurching in a hard to control manner and B) this is definitely not good for the car.

I would suspect the issue is with the crankcase ventilation system or idle control system, but hands on checks will need to be made to verify

if you need a good non dealer option to cut down on costs, check out www.bimmershops.com or www.bimrs.org for options.

Please let me know if you have further questions. Please do not forget to click a positive rating as this is the only way I receive credit for my answer, thank you. Best wishes with your vehicle...
