An MOT test is a crucial annual check to ensure your vehicle is roadworthy and meets legal safety standards. However, many cars fail their MOT for preventable reasons. At German Automotive, we believe in keeping you one step ahead by identifying the most common MOT failures and how to avoid them.

Top reasons for MOT failures and how to prevent them
1. Faulty lights and indicators

Why it fails: Around 30% of MOT failures are due to defective lights, indicators, or brake lamps.
Prevention: Before your MOT, check all lights, including headlights, indicators, brake lights, and number plate lights. German Auto can help you to replace any faulty bulbs with the correct ones.

2. Worn or damaged tyres

Why it fails: Tyres must have a minimum tread depth of 1.6mm. Cracks, bulges, or excessive wear can cause a fail.
Prevention: You can check your tyre tread using a depth gauge, its also worth checking for uneven wear or damage.

3. Brake issues
Why it fails: Low brake fluid, worn pads, or discs that are below the required thickness can lead to an MOT failure.
Prevention: Listen for unusual brake noises and check for a soft or spongy brake pedal. Regular servicing helps catch brake wear before it becomes a problem.

4. Suspension problems
Why it fails: Worn shock absorbers, broken springs, or uneven suspension can make your car unsafe to drive.
Prevention: If your car feels bouncy or unstable when cornering, it could be a suspension issue. Our technician can check your car before the MOT to prevent failure.

5. Windscreen, wipers and washers
Why it fails: Cracks larger than 40mm in the windscreen or ineffective wipers that leave streaks can result in a failure.
Prevention: Inspect your windscreen for cracks and ensure wiper blades are in good condition. It's also worth topping up your washer fluid before your MOT.

6. Exhaust emissions and leaks
Why it fails: Excessive smoke or leaks in the exhaust system can cause a failure, particularly in diesel vehicles.
Prevention: Regular servicing, using quality fuel, and ensuring the DPF (diesel particulate filter) is clean can help keep emissions low.

7. Number plate issues
Why it fails: Incorrectly spaced, dirty, or damaged number plates can cause an MOT failure.
Prevention: Ensure your number plate is clean, clearly visible, and meets legal spacing requirements.
