My Renault smells strongly of gas

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

🚨 Don't change parts randomly

When a Renault smells strongly of gas, it can be due to multiple factors: from a simple dirty spark plug to a catastrophic failure in the injection pump or catalytic converter.

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.
