Welcome. Please take a minute to click user cp and edit details so you can add your vehicle and location to your profile, that's often useful information when you're seeking assistance.
Also, please note that you have a W203 model, and there is a forum specific to it, so cruise down the main forum page until you see it (under the sedans section). This general forum is just that, general things of interest across various vehicle lines.
The ticking could be something or not, but trying to diagnose a noise on the internet is pretty tough. You can buy a mechanic's stethoscope and that will help isolate it.
The CEL could be scores of things; that's why they make code readers. If you're not in CA, you can get them read at Autozone or you can buy a basic code reader on Amazon for under $25 (so long as you live in the US). Once you have the codes, that will tell you why the CEL is on and will also point you to the fix.
Socialism is a philosophy of failure, the creed of ignorance, and the gospel of envy; its inherent virtue is the equal sharing of misery. (Winston Churchill)
