You don’t need to be a mechanic to know when something isn’t quite right with your car. A new noise, an unfamiliar warning light or even a change in the way the vehicle feels can be its way of telling you that something needs attention.
You may not be able to diagnose the exact fault yourself – and that’s perfectly fine. Knowing what to look and listen for can help you recognise a problem early and give your garage useful information when you bring the car in.
Start With the Dashboard
Modern cars monitor hundreds of functions, so a dashboard warning light is often the first indication of trouble.
As a general guide, red warning lights require immediate attention, while amber or yellow lights will usually indicate a fault that should be investigated as soon as possible.
Don’t assume that a warning light tells you exactly which part has failed. An engine management, ABS or emissions warning can have numerous possible causes. Diagnostic equipment allows a technician to interrogate the vehicle’s electronic systems and use the information as a starting point for finding the actual fault.
Listen for Something Different
You drive your own car regularly, which means you’re surprisingly well placed to notice when it starts sounding different.
Squealing, grinding, knocking, clicking, rattling or hissing can all be useful clues. Rather than trying to identify the component yourself, make a note of when the noise happens.
Does it happen when braking? When turning? Going over bumps? Accelerating? Only when the engine is cold?
Knowing what the noise sounds like, where it appears to come from and when it occurs can be extremely useful to the technician investigating it, saving both time and your hard-earned money.
Pay Attention to How the Car Feels
Not every fault makes a noise or illuminates a warning light.
A car pulling to one side, unusual vibration through the steering wheel, a brake pedal that feels different, difficulty selecting gears or an engine that suddenly feels less responsive can all indicate that something has changed.
Don’t dismiss a symptom simply because the car still drives. Problems are often easier – and sometimes considerably cheaper to rectify when they’re investigated early.
Look Under the Car
A quick glance underneath your parked car can occasionally reveal a problem before you’ve noticed anything while driving.
Air-conditioning systems can leave harmless water beneath a vehicle, but oily or coloured fluid deserves investigation. Engine oil, coolant, brake fluid and transmission fluid can all leak, and identifying the source isn’t always as straightforward as identifying the colour of the puddle.
If you’re unsure, don’t touch or taste an unidentified automotive fluid. Take a photograph and arrange for the vehicle to be checked.
Smells Matter Too
Unusual smells shouldn’t be ignored.
A burning smell could indicate an overheating electrical component, clutch or brake problem. A strong fuel smell may indicate a leaking fuel line, an injector fault or holed fuel tank, while a sweet smell can sometimes be associated with leaking coolant.
If you notice excessive smoke, a strong fuel smell, overheating or anything suggesting an immediate safety risk or serious mechanical problem, then stop somewhere safe rather than continuing your journey and making matters worse.
You Don’t Need to Diagnose It – Just Describe It
One of the most useful things you can tell your mechanic isn’t what you think is broken, but exactly what the car is doing.
Try to remember when the problem started, whether it’s constant or intermittent, whether it changes when the engine is hot or cold, and what you were doing when it occurred.
Those details can provide valuable clues and help make diagnosis quicker and more accurate.
