Hello, I"m Brandon - BMW TECH.

There are two common fixes for this misfire code. One or more ignition coil is bad. You will need to purchase an OE replacement coil to replace it.

Expert:  internal88 replied 1 year ago.

The second one is Crankcase Ventilation Control Valve is damaged.

Expert:  internal88 replied 1 year ago.

I would recommend changing the the coils first with fresh NGK spark plugs.
