My Audi blows blue smoke from exhaust

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

🚨 Don't change parts randomly

When a Audi blows blue smoke from exhaust, 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 straight to the mechanic without knowing the error code usually ends in huge bills, as many shops will start changing components blindly to see if it fixes it.
