Test drive it again, accelerated and the same light came on. Do anyone know the issue, the hidden code was useless (B7F668 Envi 16777216 Env2 195448573). The more research I do, people are saying it's the high pressure fuel pump, does that make sense or do I need to take it in the shop? Your help is appreciated!

Code B7F668 - usually comes after flashing/updating the car... Could also indicate battery is going bad... I didn't find anything for the other two codes.
Just go to bmwfault.codes on the browser and look up the codes for full description.
