Exhaust Repairs in South Knighton

South Knighton is a small rural hamlet on country lanes in the Newton Abbot area. Lane driving means low speeds, plenty of cold starts and short trips, and the exhaust pays for it: condensation sits in the pipes, soot builds in diesel filters and rust eats from within.

Automaster is a garage at Longcombe Cross near Totnes, and we repair exhausts, fit replacements and diagnose emissions systems on petrol and diesel vehicles. This guide explains the common faults and what to tell us when you ask for a quote.

Why do cold, short trips damage an exhaust?

Every time you start the engine, steam is produced as part of combustion. On a long run it exits as vapour, but on a short run it condenses inside the system and sits there. That moisture combines with exhaust acids and corrodes the rear silencer in particular.

You may spot flaking rust, a blow at the back box or a pipe that rattles in its mounting. Drivers on rural lanes often see this sooner than people who cover steady main-road miles.

What does a blocked DPF feel like?

Typically the car loses pep, the DPF symbol appears and the fans or idle may behave oddly after a drive. A diesel that is used only for brief outings may never complete the regeneration cycle, so soot accumulates until the system complains.

If you see the warning, check the handbook for advice, take a longer steady drive if it is safe to do so, and ask us to look at the car if the light persists. The cause might be as simple as driving pattern, or it might be a faulty sensor or an engine issue.

• Weak acceleration
• Engine warning light
• Smell of hot or burnt fuel

Is an MOT emissions failure an exhaust problem?

Often, but not always. Excess smoke or gas readings can come from a leaking system, a tired converter, a sensor fault or the engine itself. Looking only at the tailpipe may miss the real cause.

We start with diagnostics and a visual check of the system so the repair addresses the cause, not just the result.

What if I smell exhaust inside the car?

Stop driving as soon as it is safe, open the windows and have the vehicle checked. The gas contains carbon monoxide, which is harmful, and a leak should never be tolerated. Overheating or a sudden loss of power should likewise be treated as a reason to stop.

Do you cover South Knighton and where is the garage?

We do. Our garage, Automaster, is at Longcombe Cross near Totnes, and drivers from South Knighton, Newton Abbot, Heathfield, Liverton and Abbotskerswell come to us for exhaust work. When you ask for a quote, give us the registration, make and model, whether it is petrol or diesel, and describe what you have noticed. Cost is driven by the parts and the condition of the system, so details matter.
