My e60 has 95698 miles on it and the SES light is on.
I have changed my spark plugs, two front o2 sensor, gas cap and crankcase vent valve. (Replaced in that order)
I had the dealer ship do a diagnosis for $110 after i changed gas cap, and they told me it was the leaking crankcase vent valve.
After replacing the crankcase vent valve i am still getting ODBII codes 300 (random misfire), and 303 (misfire on cylinder3) , 304 (misfire on cylinder4), 305 (misfire on cylinder5).
Is there a way to test coils with ohm meter?
Need help cant pass emmisions

Did all three errors 303, 304, 305 start at once? Very unlikely that 3 coils went at once. Have you gone through at least one tank of gas with these codes?

I cleared the codes and filled up using premium.
I will drive it and see if codes re appear on same cylinder and then move them!

From ODB-Codes.com: Random misfires that jump around from one cylinder to another (read: P030x codes) also will set a P0300 code. The underlying cause is often a lean fuel condition, which may be due to a vacuum leak in the intake manifold or unmetered air getting past the airflow sensor, or an EGR valve that is stuck open.

Thanks for the the help.
I found what was causing the issue.
It was my DISA valve (air adjuster valve) it was broken.
I found it on the link below.

I also cleaned my Idle air control valve while i had everything apart see link below.
