Symptoms of catalytic converter damage

Below are typical symptoms of catalytic converter failure:

  • Check engine: The check engine light appears on the dashboard.
  • Engine power loss: Loss of vehicle dynamics and difficulty accelerating.
  • Increase in fuel consumption: Increased fuel demand without changing driving style.
  • Unpleasant exhaust smell: Perceptible smell of sulfur in the exhaust fumes.
  • Unusual noises from the exhaust system: Knocking and metallic sounds when the engine is running.

Can I continue driving?

Continuing to drive with a damaged catalytic converter is possible, but not recommended. In the long run, this reduces the vehicle's performance and may result in further damage, including engine control module failure.

Consequences of ignoring the problem

Ignoring a damaged catalytic converter carries serious risks to your engine and can lead to:

  • Damage to other exhaust system components.
  • Increased emissions of harmful substances.
  • Problems with passing periodic technical inspections.
  • Possible damage to engine control modules.

When is replacement necessary?

Replacing the catalytic converter becomes necessary when:

  • Computer diagnosis indicates its malfunction.
  • There are persistent symptoms of failure, such as: check engine or power loss.
  • The vehicle fails exhaust emissions tests.
