When your vehicle fails its MOT test in Maidstone, it can be stressful and inconvenient. At Malling Repair Service, we help you understand why it failed and how to fix it quickly. Each MOT failure comes with a VT30 Refusal Certificate, which lists the failure reasons and corresponding MOT failure codes, all recorded in the official DVSA MOT database.
By understanding these codes, you’ll know exactly what went wrong and how to get your car back on the road safely.
What Is an MOT Test?
An MOT (Ministry of Transport) test is a legal annual inspection required for all vehicles over three years old. It ensures your car meets strict safety, emissions, and roadworthiness standards.
If your vehicle fails, you’ll get a list of issues to repair before it can pass. At Malling Repair Service, we offer FREE MOT retests (terms apply) and can carry out the necessary repairs on-site to help you pass without hassle.

Understanding Your MOT Failure Certificate
Your MOT Refusal Certificate (VT30) includes the section code and reason your vehicle failed.
For example, if you see a code like 6.1.b.2, here’s what it means:
- 6: Body, Structure, and General Items
- 1(b): Specific inspection point
- 2: Detailed reason for failure
Below is a breakdown of the main MOT test sections and what each includes.
1. Lamps, Reflectors and Electrical Equipment
Lighting and electrical faults are among the most common MOT failures. These components ensure visibility and communication with other drivers.
Items Checked:
- 1.1 Front and Rear Position Lamps

- 1.4 Indicators and Hazard Warning Lamps
- 1.5 Rear Reflectors
- 1.6 Horn (Audible Warning)

Tip: Always test all lights before your MOT, a blown bulb can cause an instant fail.
2. Steering and Suspension
Your steering and suspension are vital for vehicle control and comfort. MOT testers look for excessive play, corrosion, leaks, and general wear.
Items Checked:
- 2.1 Steering Control
- 2.2 Steering System
- 2.3 Power Steering
- 2.4 Suspension Components and Mountings
- 2.5 Front Suspension, Wheel Bearings, and Driveshafts
- 2.6 Rear Suspension
- 2.7 Shock Absorbers
Pro Tip: If your car pulls to one side or rides unevenly, get your suspension checked before your MOT.
3. Brakes
A safe braking system is crucial for your MOT pass. The braking performance, balance, and components are tested using specialist equipment.
Items Checked:
- 3.1 Parking Brake Control
- 3.2 Hand Brake Valves

4. Tyres and Road Wheels
Tyres play a key role in safety and grip. MOT testers inspect their tread, structure, and mounting.
Items Checked:
- 4.1 Tyres: Type, Size, Load Rating, and Tread Depth

Legal Requirement: Tread depth must be at least 1.6mm across the central three-quarters of the tyre.
We stock premium and budget tyres to suit every vehicle.
5. Seat Belts and Supplementary Restraint Systems (SRS)

Items Checked:
- 5.1 Seat Belt Requirements
- 5.2 Seat Belt Condition

Tip: Ensure all seat belts fasten, retract, and lock properly. An airbag warning light will lead to an automatic fail.

- 7.2 Fuel System Integrity

If your car fails on emissions, the issue may be with your DPF, O2 sensors, or catalytic converter. We diagnose and repair all emission faults.

Items Checked:
