Exhaust Repairs in Paignton

Paignton is a seaside resort with a pier, a harbour, a zoo and a busy seafront, and in summer the traffic along the front can crawl. Slow, short, stop-start trips mean exhaust systems rarely get fully hot, and moisture lingers inside the pipework.

That is why we see rotten silencers, stuck DPFs and emissions warnings on cars from places like this. Automaster handles the full range, from a loose bracket to a catalytic converter or particulate filter fault.

Why does my exhaust keep rusting from the inside?

Every cold start produces water vapour in the exhaust. If the car only makes short hops along the seafront and back, that water never fully burns off, and it sits in the silencer and pipes. Salt-laden air adds to the corrosion outside.

The result is thin metal that splits or blows at the joints. Sometimes only a section needs replacing, and sometimes corrosion has spread too far and it is more sensible to replace more of the system. We can only say once the car is on the lift.

Mounting rubbers perish too, and a pipe that is no longer held properly can crack at the weld or rub through against the underside of the car.

• Rattling box
• Fumes smell at traffic lights

My diesel has a DPF light on. What now?

The filter is probably struggling to clear itself. Regeneration needs the engine properly hot and a steady run, which crawling along the front rarely provides. If the light stays on, or the car loses power, book it in promptly.

Ignoring a DPF warning risks a fully blocked filter. We use diagnostics to check soot loading and related sensors, then explain whether cleaning, a forced regeneration where suitable, or something larger is needed.

How do emissions faults connect to the engine?

The engine management relies on sensors in and around the exhaust to balance fuel and air. If one fails, the engine may run rich or lean, set a warning light, and push the emissions reading up. The fault can sit in the engine, not the exhaust.

This is why we diagnose first. Replacing a catalytic converter without finding the cause can mean the new one is damaged again.

Do you take Paignton cars for exhaust work?

Yes. Our garage is at Longcombe Cross near Totnes, and Totnes is the nearest town to us. We also look after cars from Brixham, Churston and across Torbay.

Mention whether it is petrol or diesel when you get in touch, since that shapes what we check.

What should I tell you when asking for a quote?

Give us the vehicle, fuel type, any warning lights, and what you hear or smell. A quote depends on how much of the system is involved, whether a catalytic converter, DPF or sensor is part of it, and the condition of the fixings.

Please ask us for a quote before booking so you know what to expect.
