Car Trouble Diagnosing

Diagnosing Vehicle Faults: When to Visit a Mechanic

At Shelly Motors Middleton Garage, we understand how important it is to keep your car running smoothly. Spotting problems early can prevent costly repairs and keep you safe on the road. Here are some of the most common signs that your vehicle may need professional attention.




Warning Lights on the Dashboard

If a warning light appears on your dashboard, it’s your car’s way of telling you something isn’t right. A glowing check engine light could mean anything from a minor sensor fault to a serious engine issue. A battery light often points to charging problems, usually involving the alternator or battery itself. If the brake warning light comes on, it may be due to low brake fluid or worn brake pads, while an oil pressure light signals that your engine isn’t being lubricated properly — a problem that can quickly lead to severe damage if ignored.

Engine noises

 

Unusual Noises

Your ears can be just as useful as your eyes when it comes to diagnosing faults. Knocking or tapping sounds from the engine may suggest worn components or low oil levels. Squealing or grinding when you brake is usually a sign that the pads or discs are worn. A whining noise from the transmission could mean low fluid or internal wear, while rattles or excessive loudness from the exhaust often indicate damage or leaks.




Battery and Electrical Issues

If your car struggles to start, especially on cold mornings, the battery may be failing. Dim headlights or flickering interior lights are another clue that the electrical system isn’t performing as it should. You might also notice that accessories such as windows, the radio, or air conditioning stop working properly. Corrosion around the battery terminals is another warning sign that shouldn’t be overlooked.

Exhaust Smoke

 

Other Signs to Watch For

Sometimes problems show themselves in other ways. Fluid leaks under the car — whether oil, coolant, or brake fluid — should always be checked. Vibrations through the steering wheel or pedals often point to issues with tyres, suspension, or brakes. Smoke from the exhaust can also be telling: blue smoke suggests burning oil, white smoke may mean coolant problems, and black smoke indicates excess fuel consumption. Even a sudden drop in fuel economy can be a sign that something isn’t right with the engine or its sensors.
