Engine Light appears on Dashboard:
I have a 2000 Mercdes C230 in graet condition with no problems at all. It is good on Gas and takes a higher octane of gas to run.
Lately the engine light comes on every 3 days. I took the car in and they told me the engine is fine it seems to be a loose wire. It was fixed but it did appear to come on again after 3 days.
It is making it hard to have the emission test on it because of this light. What do you think the problem is? Can it be fixed? I want to keep this car for another 5 years.
