Coils and Plugs replacement advice
So I went to a parts store and got a code reading because I had my engine light come back on.
The OBD sensor indicates :
Cylinder 6 misfire detected
Code : P0306
The guy said to change the 1 coil and all the spark plugs.
He said the coil was Bosch and the sparks were special? Since I'm planning to do it myself, should I get the best parts or even upgrade parts? Also is changing one coil enough?
I remember having this problem around 6-8months ago and the dealer said to change all coils and plugs for around $275 each so I said forget it. Just do the one.
I'd like to do it myself, but I dont know how. Any Detailed DIY's and tool suggestions would be appreciated
TIA

spark plugs are not special. just pick up the bosche plugs. you can use NGK or Denso. Doesn't matter. I prefer bosche. It was OEM for all my bimmers. They were 2 prong, but I use the 4 prong.
And sorry to say, but this guy is giving "shot in the dark" advice. Change the plugs. I do this every 30-40K miles. If problem is still cylinder 6 then swap the coil with another coil and see if it's the coil. I don't remember how the cylinders are lined up but perhaps someone can chime in.
Give your car/engine details and see if someone knows. I don't think they are 1,2,3,4,5,6 but assuming they were you take coil 6 and swap it with coil 1 and if it's the coil you would have the misfire on cyl. 1 so then just replace that specific coil.

My Ride: 2006 530i
I had the same issue with my '06 530i. It was a bad ignition coil. I went Autozone and bought a replacement for $53 and was back running smoothly in about an hour. It's an easy fix. The worst part of the job is removing all the plastic & the strut brace.
There's a DIY video at bavauto.com: DIY Video – BMW “Pencil Style” Coil Replacement – Install How To – M54, M62, N62 | Bavarian Autosport Blog
This helped me get through the job quickly.

My car is a e60 530i sorry...forgot to mention that.
Now I feel more confident doing the job myself.
The video is awesome but doesn't show how to remove the plug once the coil is out.
Also...is cylinder six the one furthest away? I'm thinking that one would be the hardest to replace.

When I performed the job, I probably went too far in clearing the engine area. I pulled the cabin filters & housing, strut brace, and then the plastic cover on the engine. I thought the bad coil back was toward the fire wall and I wanted more clearance. It was actually closer to the front side of the motor.

I believe the firing order runs sequentially from 1 thru 6. Cylinder #1 is closest to the radiator and #6 is by the firewall. As I recall the cylinder # is on the valve cover, but don't quote me on that.
