'07 325i

Driving home tonight my engine revs felt off and i could see they weren't as steady as normal, as i tried accelerating slowly the engine struggled slightly and then the engine warning light came on.

I pulled over and took a video:

Just wondering if anyone had any experience with this kind of problem? So i can gauge if it's going to cost a fortune or not.

It drove home okay with me being very careful. Obviously i'll get it to a garage soon though.

Thanks for any input you have, will be appreciated.

Do you have rough vibrating sound at idle after the car is warmed up? In that case I suspect one of the ignition coils went wrong.

I had vibrating sound at idle and eventually the small yellow engine light came out as well. After reading the OBD code it was due to failed ignition coil of a certain cylinder and car went fine after the coil replacement...

Usually ignition coils, and have you changed plugs
Also eccentric shaft sensor and or dirty vanos solenoids.
