Car Diagnostics in Caton

Caton is a small rural hamlet on the Dartmoor edge near the A38. Cold mornings, damp air and a drive that starts straight into the lanes put the starting and charging systems under strain.

Our garage, Automaster, is at Longcombe Cross, Longcombe, near Totnes. Drivers from Caton and nearby Bickington, Pounds Gate, Hexworth and Buckfastleigh come to us for diagnostics and auto electrics on petrol and diesel cars.

Why does my car struggle to start on cold mornings?

A battery delivers less in the cold, and an engine is harder to turn over, so a battery that was fine in summer can fail in the first frost. Diesel cars can add glow plug trouble to the mix, with a coil-shaped dashboard light and hard starting.

Slow cranking is the early warning. If you notice it, have the battery and charging system tested before the car fails to start at all. Corroded or loose battery terminals can mimic a dead battery, so the connections get checked as part of the same test. Lanes with standing water and mud can also splash the engine bay and starter, which adds to the wear.

Do I need a new battery, alternator or starter motor?

These three parts are linked, and testing separates them. A load test shows the battery's condition, an output test shows what the alternator delivers, and checking current draw shows whether the starter motor is healthy.

We carry out battery replacement, alternator replacement and starter motor replacement once the fault is confirmed. Some modern cars need the new battery registered, and the right type matters, so give us the vehicle details when you ask for a quote.

What will a diagnostic scan find?

The scan reads stored fault codes and live data. It does not name the broken part. A fault code points to a circuit or system, which gives the starting point for further tests.

Warning light diagnostics cover the engine management light, ABS, airbag, power steering and other systems. An amber light that stays on is a request to get the car checked; a red oil, temperature or brake light means stop safely.

• Engine management light
• ABS and traction warnings
• Airbag light
• Power steering warning

Wiring repairs, immobilisers and parking aids

Damp air and old insulation lead to wiring faults, and corroded connectors cause odd behaviour like flickering lights, dead windows or a reversing camera that shows nothing. Repair means finding the break, not guessing.

Immobiliser faults, key recognition problems and alarms are part of the same area. They take careful testing because the systems differ between makes.

Is the garage easy to find from Caton?

We are at Longcombe Cross, Longcombe, near Totnes, TQ9 6PL. Drivers from the hamlets and countryside on the Dartmoor edge use us, along with those from Bickington and Buckfastleigh.

If the car has stopped being safe to drive, with a red warning, cutting out or lights failing, do not push on to the garage. Describe the problem when asking for a quote.
