I wish to change the spark plugs on my C240 Sport but I am not sure how to access them on this car. I have previously had them replaced by the dealer as part of a service and they have told me it is a difficult job on this engine. (V6, built in 2000).
Can someone tell me what I need to take off the engine in order to get to the plugs and any other useful information I may need in order to do this job please.
I cannot obtain a manual for this vehicle anywhere. Any ideas anybody?
