Hi,

(Someone referred me to this section of the forum, this is for an E60 N52 2009 528xi)

I had a P0305. Since I just hit 100k miles I replaced all spark plugs and coils.

After swap I got:
P0303
p0304
p0300
P316a
B2aaa



  1. I took out 3 and for in case i had a bad connection and reinstalled - same problem
  2. Swapped 3 and 4 - Same problem
  3. Put one of the old working coils on 4 - same probelm
  4. I reseted codes every time
  5. Unplugged the battery for 1/2 hr and unplugged battery:
    1. After doing so, i started the car and the check engine light never went away even after resetting the codes
    2. I tried driving the car and it fells rough



I can't find anything out there that shows these mixed problems. It doesn't make sense after I put all new. Also how does it go from p0305 to all of of those issues with new stuff?

Please help!

Thank you,
