My Ride: 318i n46 e46, e34 M5
318i Dead ignition coil

So on Wednesday I probably did about 100km of driving all up when I pulled up at a red light and when to take off and experienced a severe loss of power, shuddering and a engine light turn on.

Pulled over, plugged in my small bluetooth OBD scanner that I keep in the sunglasses compartment and received a 0301 Cylinder 1 misfire.

I started the car again and the misfire was consistent (it wasn't firing at all). The idle was rough but steady so I decided to pull out and see how it drove.

After the car got going over 1,500-2,000 RPM the misfire wasn't noticeable and was going smooth but there was a definitely lack of power.

I drove the short 10~ minute drive home from where I was, pulled up in the drive way and got testing.

Knowing that I replaced the spark plugs not to long ago I figured it was most likely a coil. I swapped the coil on cyl 1 with the coil on cyl 2, started the car up again - no change - whilst still running with coils 1 & 2 swapped I disconnected the cable from the coil pack and it dropped another cylinder and started noticeably shaking more almost stalling out so I immediately connected it back.

Hopped online that night purchased a new coil from Clickable Automotive who was hospitable enough to let me pick it up first thing in the morning which I did, installed it worked great.

Codes are now cleared and car is back to normal.
