Ignition Coil Replacement

I have a bad coil and was going to have them all replaced on my 2005 545i with 80,000 miles. Last summer already has the plugs and wires changed. I'm in a pinch for cash and deciding to just change the bad one. Viewed a video on it and seems fairly simple. Any additional directions and/or suggestions for the ignition coil replacement and code reset would be greatly appreciated. Thank you.

It is stupid easy to replace the coils, if you're in a pinch replace the one that's bad, but get an extra one - just in case. Then later, when things are better financially replace the rest.

Very easy to do.

The ones towards the back cylinders can be a pain to get to, if that's the one you need to replace. Not very hard regardless

^^^+1000 Forgot to mention that, especially the one on the passengers side - eesh!!!

I'm a bmw tech located in Long Island, ny. If you're nearby, I can perform the repairs and get you the parts cheaper. I also have all the diagnostic equipment to clear your faults/adaptations. PM me if your interested

Thanks, but I am way upstate in Rochester. I'm saving a few bucks by doing this job myself as this is one I am capable of performing... thanks to forums and decent people on them looking to help anyone ambitious. If you know which cylinder is # 6, this will save time, but seems to be a simple test to determine which coil is malfunctioning. Best regards!!!

Thanks for the tips and options. Took me a couple hours to change all 8 coils along with some moments of second guessing, but patiently worked through it and my reward is she runs beautiful! My hats off to BMW engineering. Technology and simplicity at it best. Ciao
