My Mercedes-Benz has a flashing check engine light

Why does this happen and how to avoid being scammed at the shop?

🚨 Don't change parts randomly

If you've noticed that your Mercedes-Benz has a flashing check engine light, you should know that the causes vary widely. It could be a minor sensor fault or a warning of a serious powertrain breakdown.

Going to a traditional mechanic with such a generic symptom often ends in "repairs by elimination", where you will be charged hundreds of dollars changing parts until the problem goes away.
