Fault Codes 29E0 & 2A94 Need Help

[Heartlover]

Hi,

I have a 2007 BMW 335i and I just started getting fault codes 29E0 - "Fuel Mixture Control" and 2A94 - "Crankshaft sensor." It just started yesterday. My car died out of the blue while at a stop light. I restarted and drove it for awhile before it lost power on the freeway and surged then it got power again but it went to half power/safe mode and gave me a symbol on the dash of a triangle with an exclamation point inside of the triangle, and the triangle is inside of a circle. Now it takes a long time before the engine starts and it immediately gives me that same symbol (triangle/circle) and it goes to half power - also fault code 3100 "Boost pressure control."

Does anyone have any experience with any of these codes?

Thank you for your help!
