Exhaust Repairs in Hexworth

Hexworth is a small rural hamlet reached by narrow lanes on the Dartmoor edge. Lanes like these are rough on the underside of a car, and many trips are short, which leaves moisture in the exhaust and starves a diesel filter of the heat it needs.

Our garage, Automaster, is at Longcombe Cross near Totnes. We work on exhaust systems, catalytic converters, diesel particulate filters and emissions faults for petrol and diesel vehicles. The notes below explain what to watch for and how to ask for a quote.

What usually goes wrong with exhausts on rural lanes?

Grass banks, ruts and loose stone can bend or crack pipes and break rubber mounts. A hanger that fails lets the system sag and knock, and the extra movement fatigues welds and flexible sections. You may hear a clunk over a bump before you hear a blow.

Time also plays its part. Short trips mean the exhaust never fully dries, so rust develops from within. Heat shields are thin and can corrode away entirely, leaving a metallic rattle.

• Clunk or knock over bumps
• Rattle from a heat shield
• Pipe sagging or touching the ground
• Noise that gets worse with revs

Why does my diesel warn me about the particulate filter?

Soot from a diesel engine collects in the filter and is burned off during a regeneration cycle. Regeneration needs the exhaust to run hot for a sustained period. If most of your outings are short ones along the lanes, the cycle may keep getting interrupted and the filter fills.

An amber light is an early request for help. Check your handbook for advice on a longer drive, and if the light stays on or comes back, get it diagnosed. Carrying on for weeks risks limp mode and a harder, more involved job.

Could a warning light be about something other than the exhaust?

Quite possibly. Emissions systems depend on sensors and the engine's condition, so a warning light may come from a sensor, a vacuum or intake leak, a misfire or a fuel-related fault. We read the codes, check live data and then inspect the system itself.

That approach prevents guesswork and avoids fitting parts that do not cure the problem.

Can I keep driving if I smell fumes?

No. If fumes get into the cabin, open the windows, stop in a safe place and have the car checked, because exhaust gas contains carbon monoxide. The same goes for any sudden loss of power or a smell of burning that suggests something is overheating.

Do you cover Hexworth, and how do I get a quote?

Yes. Hexworth is a small place, but drivers from there and from nearby Heathfield, Liverton, Bickington and Caton come to Automaster at Longcombe Cross near Totnes. To get a quote, tell us the make, model and registration, whether the car is petrol or diesel, and what you can hear, smell or see. Cost depends on which parts are involved and the state of the fixings, so we prefer to quote from details.
