Fella's,
My manual isn't very clear on this, and I want to know what I can expect: do I have to remove all the ignition coils in order to change the plugs on my W210?

THANKS!

Ok, sounds like you have a 4cyl version of the 210.

There are a few versions of the 111 engine so I'll mention the job vaigly.

If you have the intake pipe over the rocker cover you'll need to remove it, remove the cover in the middle of the rocker cover (usually 3 bolts). If you have ignition leads with twin coils then remove the leads, if you have 4 coil packs then remove all coil packs after disconnecting the wiring, if you have 2 coil packs with leads then remove the packs and leads.
Replace spark plugs

Don't mixup the coil pack wiring.
