Catalytic Converters in Tyne and Wear

A catalytic converter sits in the exhaust system and turns harmful gases from the engine into less harmful ones. It contains precious metals, which is part of why it is an expensive component and a target for thieves.

At Banks of the Tyne in Hebburn we diagnose catalytic converter problems and replace converters, alongside our wider exhaust and emissions work for drivers in Tyne and Wear.

Signs of a failing converter

Symptoms vary, and several overlap with other faults, which is why testing matters. A warning light on the dashboard is common, as is a loss of power, especially when you ask the engine to work harder.

• Engine management light on
• Noticeable loss of power or sluggish acceleration
• A rotten-egg smell from the exhaust
• Rattling from underneath, suggesting broken internal material
• Failing the emissions part of an MOT

Why they fail

Converters rarely fail on their own. Misfires, oil burning, coolant leaks and an over-rich mixture can all damage one, and so can physical impact. If the cause is not found, a new converter may fail again.

That is why we start with diagnosis. A fault code or a poor reading may point at a sensor, not the converter itself, and replacing the wrong part costs you money for no gain.

What replacement involves

Once the converter is confirmed as the problem, the old unit is removed and a new one fitted, along with any gaskets, fixings or damaged sections of pipe that need renewing. Sensors fitted close to the converter are checked at the same time.

Cost depends on the make and model, whether the converter is built into the manifold or sits further back, and which type of replacement is suitable for your car. Ask us to explain the options at the estimate.

Theft, damage and what to do next

If your converter has been stolen you will notice a loud, harsh exhaust note straight away. Do not keep driving it for long, as it is unpleasant and may not be legal. Check with your insurer about your own situation.

If a warning light comes on with flashing or severe misfire, ease off and get the car looked at promptly, as unburnt fuel can damage the converter quickly.
