Howdy all,

Finally getting around to some maintenance on this C230 and ran right into trouble changing spark plugs. Could be simple, but being this is the first German car I've owned I'm not familiar with their construction quirks. Anyone out there been through this procedure themselves and mind sharing tips & techniques? Plugs 2 & 4 have coils attached to them and the others have what appear to be screw in wire harnesses. I have a subscription to AllDataDIY but their docs don't have anything on an R&R process. Thanks in advance for any info provided.

Best regards,

Steve

yeah remove the 3 coils per bank using a t30 socket and then remove the coils, 1 coil pack per 2 plugs, its easy probably need a small prybar to get them off.
