I haven't had to do this yet, but doesn't look to hard based on the FSM.
As soon as I throw this code, I'll be doing it myself and i'll take pictures.
May want to check out this thread so you can at least see the diagram on the M45 and where it is:

when i put my new undertray from Tollboothwilley, I saw it and it is held in place by one bolt + the connector, so should be quite easy to do.
get yourself some sturdy jack stands or ramps (ramps are easier, just can't pull the tires off) and a slim profile 2-3 ton jack and you can do a whole lotta stuff on your ride.
don't know about changing both since I haven't had to do this yet, but might be smart to do it if you're swapping one out..."an ounce of prevention is worth a pound of cure." swapped my PCV valves, spark plugs, and just changed my belts -- pretty darn easy once you've got the FSM and you look at the How To & FAQ section.
