If your car’s MOT test date is approaching, it’s important to make sure your vehicle is in good condition. Many vehicles fail their MOT because of small issues that could easily be fixed with basic servicing.
At Brunswick MOT Centre, professional technicians often see vehicles failing MOT tests due to problems that drivers didn’t notice beforehand. Knowing the warning signs early can help you avoid unnecessary stress and repair costs.
Here are seven common signs that your car may need servicing before its MOT test.
1. Warning Lights on the Dashboard
Modern cars are equipped with dashboard warning lights that indicate potential problems.
Common warning lights include:
- Engine management light
- Brake warning light
- ABS light
- Battery light
If any of these lights remain on, it could indicate a fault that may cause your vehicle to fail its MOT.
2. Unusual Noises While Driving
Strange sounds coming from your car are often a sign that something isn’t working properly.
Some common noises include:
- Grinding sounds when braking
- Knocking sounds from the suspension
- Squealing belts under the hood
Ignoring these noises could lead to more serious mechanical problems.
3. Worn or Damaged Tyres
Tyres are one of the most common reasons vehicles fail MOT tests.
In the UK, the legal minimum tread depth is 1.6mm. If your tyres are worn or damaged, they may not pass inspection.
Check your tyres for:
- Low tread depth
- Cracks or bulges
- Uneven wear
Replacing worn tyres before the MOT can help ensure your vehicle passes the test.
4. Poor Braking Performance
Your brakes are one of the most critical safety components of your vehicle.
Signs of brake issues include:
- Longer stopping distance
- Vibrations when braking
- Squeaking or grinding sounds
These symptoms should never be ignored, as brake faults are a common cause of MOT failure.
5. Faulty Lights or Indicators
Lights are a small but important part of the MOT inspection.
Make sure the following are working properly:
- Headlights
- Brake lights
- Indicators
- Reverse lights
- Number plate lights
A simple blown bulb can cause your vehicle to fail the test.
6. Excessive Exhaust Smoke
If your car produces excessive smoke from the exhaust, it may indicate engine or emission system problems.
Different smoke colors can signal different issues:
- Black smoke – too much fuel being burned
- Blue smoke – oil burning in the engine
- White smoke – possible coolant leak
Since emissions are checked during MOT testing, this issue should be addressed before the inspection.
7. Steering or Suspension Problems
If your car feels unstable while driving, it could be due to suspension or steering issues.
Warning signs include:
- Car pulling to one side
- Bumpy or rough ride
- Steering wheel vibrations
These issues can affect vehicle control and may lead to MOT failure.
