Question type: Maintenance & Repair

Ok guys need help. I have 06 325i i got an P0306 code here what ive done
already: new coils, new spark plugs, swap injectors, clean vanos, camshaft
sensors, sent out DME to get repaired (they confirmed that there was errors
in pluse width), check for vacuum leaks.

get a cheap hei spark tester and confirm that there is no spark to that cylinder. you can also check if spark is at the coil on number 6 with that tester. if there is spark at the coil, the it is likely a bad wire. if you have spark everywhere, check the compression on that cylinder to make sure it has compression to meet specs for your engine.
