Car Diagnostics in Newton Abbot

Newton Abbot is a market town at the head of the Teign estuary, with busy A380 and A382 junctions and routes towards Dartmoor and Torbay. Many people drive daily, which makes an unexpected warning light or a flat battery particularly disruptive.

At Automaster, we offer diagnostics and auto electrical repairs on petrol and diesel cars from our garage at Longcombe Cross near Totnes. We are an RAC Approved Garage, and drivers from Newton Abbot and the surrounding area come to us for fault finding.

Which warning lights are worth acting on straight away?

Red lights come first: oil pressure, engine temperature, brakes and charging. If one comes on, stop safely and avoid driving on. A flashing engine management light is also a reason to ease off, since an engine that is misfiring can damage the exhaust.

A steady amber engine light on a car that drives normally is less urgent, but should still be checked soon. Faults left alone often get worse.

• Red lights: stop safely
• Flashing engine light: ease off
• Steady amber light: arrange a check
• ABS or airbag light: system fault

How does a diagnostic check work on a commuter car?

We plug diagnostic equipment into the car, read stored codes and watch live values while the engine runs. That shows which circuit or sensor is out of range. We then test it and the wiring heading to it.

The scan itself is not the repair. It guides the repair. Parts are replaced after we have confirmed the fault, not on the code alone.

Because commuter cars cover regular mileage, they often give us useful patterns: a fault that always appears on the first cold start, or only on a long motorway-style run, narrows the search a great deal.

Why won't my car start reliably?

Check the basics: a tired battery, loose or corroded terminals, a starter that is wearing, or an alternator that has stopped topping up the battery. Cold mornings on the edge of Dartmoor can expose an already weak battery.

We test each part of the chain. If a battery is needed, we fit one suited to the car, and please tell us if the car has stop-start.

A starter that has begun to labour can also drag the battery down, so the two are checked together rather than in isolation.

Do you cover Newton Abbot, Bickington and Abbotskerswell?

Yes. Drivers from Newton Abbot, Milber, Abbotskerswell, Bickington, Heathfield and the surrounding area bring their cars to Longcombe Cross near Totnes.

For a quote, tell us the make, model, engine and symptoms. If the answer is not obvious, we will say what the first step should be.

What affects the time an electrical repair takes?

Access is a major factor, along with whether the fault is steady or intermittent, whether wiring or a part has failed and how many systems are involved. A visible damaged connector is quick. A hidden break in a loom is not.

We also work on sensors, alarms, immobilisers, reversing cameras and parking sensors. Ask for a quote and give as much detail as you can.
