Exhaust Repairs in Caton

Caton is a small rural hamlet on the Dartmoor edge near the A38, so a typical outing often combines a slow country start with a faster main-road stretch. That variety is useful for an exhaust, but it does not protect it from rust, vibration or a blocked diesel filter.

Automaster is at Longcombe Cross near Totnes and deals with exhaust repairs, replacement, catalytic converter faults and DPF problems on petrol and diesel vehicles. What follows covers the symptoms, the work and what to include in a quote request.

My exhaust has suddenly got louder. What now?

A sudden change usually means something has failed: a corroded section, a cracked weld or a gasket blowing at a joint. Drive gently and avoid revving hard, as a leak can worsen, and book it in rather than waiting for a failure at the roadside.

Once the car is on the ramp we can see whether the leak is localised or the system is generally tired. That decides whether a repair or a replacement is the sensible route.

What does limp mode have to do with the DPF?

When the diesel particulate filter is badly loaded, the engine control unit may restrict power to protect the engine and filter. The car feels flat, may refuse to rev and often shows a warning light. Sometimes the actual fault is a pressure sensor or an engine problem that has overloaded the filter with soot.

Short journeys are the most common reason for the filter loading up. If your use is mostly brief trips, the filter rarely gets hot enough to clean itself. A longer, steady drive may help in early cases, but persistent or repeated warnings call for diagnosis.

• Amber DPF symbol
• Reduced power and flat acceleration
• Engine management light
• Higher fuel consumption

How are catalytic converter and sensor problems found?

Our diagnostic equipment pulls stored codes and live sensor readings so we can see how the catalytic converter and sensors respond. We then check the converter for damage, the pipes for leaks and the engine for causes such as misfires.

A converter that is blocked or broken internally may rattle or choke the engine. One that has simply been poisoned by oil or coolant will fail again unless that leak is cured, which is why root cause matters.

Are fumes inside the car ever acceptable?

No. Exhaust gas in the cabin is dangerous because of carbon monoxide. Open the windows, stop when it is safe and arrange a check before you drive any further.

Do you work with drivers from Caton?

Yes, drivers from Caton, Bickington, Pounds Gate, Hexworth and Buckfastleigh bring their cars to us at Longcombe Cross near Totnes. With a hamlet like Caton there is no need to explain much about where you are, just tell us the vehicle and what is going on. For a quote, we need the registration, fuel type, symptoms and any warning lights or MOT failure notes.
