A cracked o r damaged fuel cap can cause multiple issues such as fuel evaporation, leading to decreased fuel efficiency and increased emissions. It can also allow dirt and moisture to enter the fuel tank, potentially damaging fuel system components. For modern Mercedes-Benz S-Class models, a faulty fuel cap often triggers the Check Engine o r Evaporative Emission System warning lights. Ignoring this can result in failed emissions tests and may affect engine performance over time.
