Um, welcome aboard.
Please click user cp and edit details so you can add your vehicle and location to your profile, that is often useful information when you're seeking assistance.
The first question I have is: WHAT are the codes? The CEL comes on for a reason, and that's to tell you it's diagnostic time, not clear-the-codes time.
Now, that said, these engines are notorious for developing misfires due to the spark plug connectors. A set of them is not expensive online. So if your code is for a misfire to cylinder 3 I would probably start with connectors. If you can find a set of wires that includes the connectors that's probably cheaper overall anyway, since those are probably the OE wires, too.
Lastly, please come join us in the W210 forum. There is lots of information about the 210 generally and your car in particular. The "general" forum is just that: general information regarding the world of MB vehicles, nothing specific about your car.
