Welcome to the 300M Enthusiasts Club message board. This link should help you. It's just a sample of what's available via the knowledgebase forum (available to members of the club).

You might think of joining the club---best investment you can make in keeping your M in good repair.

how long have you owned your M? Any other problems with it? Did you do the timing belt/water pump change yet (due at 100k)?

You really don't need a diagram. You will need to remover the coil packs on top of the engine. There is one over each spark plug tube. BE very careful with the torx head screws...some strip easily.

Check out the Spark Plug Forum for good advice on how to attack them and most recommend NGK platinum plugs

i am the third owner of my 300m... its a 2001 and a wonderful car. I got it from my mother because she got a chevy.... first thing i did was replace the tie rods... i had a good 45 degrees of play in the steering. i have not done much other stuff besides a transmission flush new oil change and new tires... it currently has 150000 miles on it... its a means of transportation for me from school (ETSU )to work to home.

you need to do the timing belt/water pump asap or risk losing your engine when it breaks

If you are referring to the Timing Belt/Water Pump "thing" it is a fairly easy although time consuming DIY and there is lots of information in the Knowledge Base for "Contributing Members"

If you don't remove the harmonic balancer, it's pretty much the use of general tools. A torque wrench would probably be the most specialized tool needed. The job can be very intimidating but after seeing it done once, I'll be doing my own come the next time it's needed.
