Our expert insights into BMW catalytic converter replacement

Our expert insights into BMW catalytic converter replacement

What does a catalytic converter do?

A catalytic converter is an essential part of your exhaust system. Its job is to change harmful substances in a car’s exhaust gasses, such as carbon monoxide nitric oxide, and hydrocarbons, into less harmful gases.

What are the symptoms of a failing catalytic converter?

Below are the top three symptoms that could indicate you need to replace your catalytic converter:

  • The smoke from your exhaust is heavier or darker than normal.
  • You smell something similar to rotten eggs or sulphur coming from your car’s exhaust.
  • You notice a reduction in engine performance.

What happens during a catalytic converter replacement?

Our certified mechanics will:

  • Raise your car completely off the ground, making sure that the exhaust has had time to cool down before they begin the replacement.
  • Locate the catalytic converter. It usually looks like a box in the middle of the exhaust system underneath the car.
  • Remove the catalytic converter, inspect it and fit a replacement if necessary
  • Test the new catalytic converter, taking care to double check that the replacement catalytic converter is up to the correct specifications for the vehicle’s emissions standards.
