You might still have some error codes stored that were not serious enough to trigger a Check Engine Light or other warning on the cluster. The best place to start is to have them read (AutoZone, PepBoys and places like them will do it for free) amd post them on the forum specific to your car. I believe you have a W203. Good Luck!
