Exhaust Repairs in Modbury

Modbury is a small South Hams market town on the A379, with narrow streets, steep approaches and rural lanes in every direction. Cars here crawl up inclines, squeeze through tight gaps and make plenty of short hops.

Those habits shape the way an exhaust ages. Automaster repairs exhausts and diagnoses catalytic converter, DPF and emissions trouble on petrol and diesel vehicles, and this page sets out what to watch for.

How do steep streets and short hops affect an exhaust?

Short trips leave moisture in the system, which rusts silencer boxes from within. Steep hills put load on the engine, so any weakness shows up as hesitation, extra smoke or poor pulling power. Narrow lanes with rough edges strike the underside.

Over time these add up to holes, loose hangers and joints that start to blow. The sooner a rattle or roar is checked, the less likely it is to become a failed section.

We look at the whole system from the manifold back, because one weak joint often sits beside other worn sections. Whatever the symptom, Automaster starts by finding out what is actually wrong before recommending parts.

• Roaring on hills
• Rust holes
• Fume smell

What does a DPF warning mean for a diesel on rural lanes?

A particulate filter traps soot and clears it by running very hot. Lane driving and short trips seldom do that, so the filter slowly fills. The first sign is a warning light, and then power can fall or the car can drop into limp mode.

Act on it promptly. We start by diagnosing: pressure sensor readings, leaks in the exhaust and any engine fault that is making extra soot. After that, cleaning, repair or replacement can be discussed. Which is possible depends on the vehicle and the condition of the filter.

Why did my car fail its emissions test?

Failures come from the catalytic converter, an oxygen sensor, a misfire, a rich mixture or an exhaust leak. The test result does not say which. Fitting a part without diagnosis risks paying twice.

We read codes, watch live data and inspect the exhaust, then explain what we found in plain terms.

Is there a garage for exhaust repairs near Modbury?

Our garage is at Longcombe Cross, Longcombe, near Totnes, TQ9 6PL. Drivers from Modbury come to us, along with people from Ermington, Ivybridge, Kingston and Kingsbridge.

When you get in touch, mention if the trouble shows on the climbs into town or on the A379.

How should I ask for an exhaust quote?

The price moves with the condition of the system, the parts it needs and the labour to remove seized fixings. A catalytic converter or DPF is more involved than a pipe or a box.

Give us the key facts when you ask for a quote and we can set out what the job needs.

• Make, model and year
• Petrol or diesel
