🌡️ Engine overheating
Signs
Temperature gauge rising, warning message, steam, coolant smell, weak AC at idle or coolant loss.
Possible causes
Leak, low coolant, radiator/fan fault, thermostat, water pump, blocked radiator or head-gasket damage.
What to do
- Switch off AC, stop safely and shut down if temperature remains high.
- Never open a hot radiator/pressurised cap.
- After cooling, check visible leaks and recovery-tank level only if safe.
- Pressure-test cooling system, test fans/thermostat and scan temperature data.
🛢️ Oil leak / oil warning
Signs
Oil spots, burning smell, blue smoke, low dipstick or red oil-pressure light.
Checks
- A red pressure light means stop the engine; oil level alone may not be the cause.
- Inspect filter, drain plug, sump, valve cover, seals and oil mixed with coolant.
- Blue exhaust smoke can indicate oil burning, turbo, valve-seal or piston wear.
- Confirm pressure mechanically before major repair decisions.
⚙️ Automatic gearbox / CVT
Signs
Delay engaging D/R, slipping, shudder, hard shifts, whining, overheating warning or burnt-smelling fluid.
Checks
- Test cold and fully warm; drive gently through all normal gears.
- Scan transmission module and review service history.
- Check correct fluid type/level using manufacturer procedure.
- Do not assume a fluid change will repair internal wear; diagnose first.
❄️ Weak or warm AC
Possible causes
Low refrigerant/leak, condenser airflow, fan, compressor, expansion valve, cabin filter, blend door or electrical fault.
Checks
- Measure vent temperature at idle and driving speed.
- Confirm condenser/radiator fans run and engine does not overheat.
- Use pressure/leak testing; repeatedly “adding gas” without fixing a leak wastes money.
- Check cooling from all vents and rear AC.
🔋 Battery / starting / charging
Signs
Slow crank, clicking, dim lights, battery light, repeated jump-starts or random electrical faults.
Checks
- Load-test battery and inspect terminals/ground cables.
- Test alternator charging voltage and parasitic drain.
- UAE heat shortens battery life; read production date and warranty.
- A battery warning while driving can mean charging-system failure, not simply a bad battery.
🛑 Brakes
Signs
Squeal/grinding, vibration, soft pedal, pulling, ABS light or longer stopping distance.
Checks
- Inspect pad and disc thickness/condition, fluid, hoses, callipers and leaks.
- A soft or sinking pedal is urgent; do not keep driving.
- Vibration can be disc/runout or suspension/tyre related—measure before replacing.
- Scan ABS faults; do not cover a warning light.
🛞 Tyres, alignment & suspension
Signs
Uneven wear, vibration, humming, pulling, clunking, bouncing or steering play.
Checks
- Read tyre size, load/speed rating and four-digit production week/year.
- Inspect cracks, bulges, repairs, tread and pressure when cold.
- Uneven wear can indicate alignment, bent chassis, worn bushes, shocks or steering parts.
- Check wheel balance and bearings; alignment alone cannot fix worn parts.
🚨 Check-engine light / rough running
Signs
Misfire, shaking, low power, poor fuel economy, smoke or warning light.
Checks
- A flashing light with shaking can damage the catalytic converter—stop and diagnose.
- Read codes and live data; a code identifies a system, not always the failed part.
- Check plugs/coils, air leaks, fuel pressure/injectors, sensors and compression as indicated.
- After repairs, confirm codes remain clear and readiness tests complete.
⚡ Electrical / flood faults
Signs
Several unrelated warnings, windows/locks failing, intermittent no-start, damp smell or corroded connectors.
Checks
- Check battery/grounds first, then fuses, wiring diagrams and module communication.
- Inspect under carpets, seats, fuse boxes and spare-wheel well for water/silt/corrosion.
- Scan every module. Replacing one module may require coding and may not cure corroded wiring.
- Severe flood damage can cause recurring safety faults; consider walking away.
💨 Exhaust smoke guide
- Blue: burning oil.
- Thick white after warm-up: coolant or other internal issue; brief cold condensation can be normal.
- Black: excessive fuel/air-control fault.
- Steam under bonnet: possible coolant leak/overheating.
Check when cold and warm; diagnose with scan, pressure, leak-down/compression or cooling-system tests as appropriate.
