Common MOT Failures and How Arrow Car Repairs Can Fix Them

When it’s time for your car’s MOT, the last thing you want is a fail and a big bill. But truth is, many MOT failures happen because of simple issues that could’ve been sorted ahead of time. At Arrow Car Repairs, we see these every day and we’re here to help you avoid the hassle.

What’s an MOT, and Why Does It Matter?

MOT (Ministry of Transport test) is a yearly check that makes sure your car is safe, roadworthy, and meets legal emissions standards. If your car is over 3 years old, it needs this test every year.

Failing the MOT means you can’t legally drive your car (unless it’s going to a garage or MOT test), and it might mean unexpected repair costs.

Most Common MOT Fails

We’ve worked on loads of MOT fails at Arrow, and here are the ones we see the most:

1. Faulty Lights and Indicators

Why it fails: Broken bulbs, foggy lenses, or lights that don’t work properly.
How we fix it: We check all lights before the MOT, change bulbs, clean lenses, and check wiring.

2. Worn-Out Tyres

Why it fails: Not enough tread depth (needs to be at least 1.6mm) or damage to the tyre wall.
How we fix it: We’ll inspect your tyres and fit new ones if needed, making sure they’re balanced and aligned.

3. Suspension Problems

Why it fails: Worn springs, leaking shocks, or parts that just don’t handle bumps properly.
How we fix it: Our team checks the suspension thoroughly and replaces any parts that are worn or broken.

4. Brake Issues

Why it fails: Pads too thin, discs too worn, or uneven braking.
How we fix it: We measure brake pad thickness, test brake response, and sort out anything that’s not safe.

5. Windscreen Wipers and Washers

Why it fails: Wipers that smear or skip, or washer jets that don’t spray properly.
How we fix it: We fit new blades and clear out washer jets, so you’ve got clear vision when driving.

6. Exhaust and Emissions

Why it fails: Leaks, rust, or failing emissions test.
How we fix it: We check for leaks, test your emissions, and repair or replace faulty parts.

7. Number Plates and Visibility

Why it fails: Plates that are dirty, cracked, or not correctly lit.
How we fix it: We clean, repair, or replace your number plates and make sure lights are working.

8. Steering Issues

Why it fails: Loose steering, power steering problems, or parts that are worn out.
How we fix it: We test steering response, check fluid levels, and fit new parts if needed.

9. Warning Lights on the Dashboard

Why it fails: Engine lights, ABS lights, or other warning lights staying on.
How we fix it: We run a diagnostic to find the issue and get it sorted before the MOT test.
