Engine, Emissions & Diagnostic Checks

Modern MOT tests include emission checks and engine diagnostics: • Make sure engine warning light (MIL) is off. • Replace clogged air filter, old spark plugs, or worn sensors. • Warm engine before the test — colder engines may read higher emissions. • Ensure exhaust system is intact, secure, and not leaking. • Use a diagnostic scan to detect hidden fault codes that might cause failure.

Battery, Fluids & Under-Bonnet Inspections

A well-maintained engine bay helps you pass without surprises: • Check oil, coolant, brake fluid, power steering fluid (if applicable). • Look for leaks, loose hoses, cracked pipes. • Inspect battery terminals — clean and tight. • Check the bonnet latch, engine mounts, visible belts & pulleys for wear.

MOT TEST

Interior & safety items: Make sure all seatbelts retract, doors open/close properly, mirrors secure, horn works, windows wind properly. •Bodywork & structure: No sharp edges, excessive rust, or corrosion. Doors, bonnets and boot must latch securely. • Lights & number plate visibility: Plates must be clean, legible, correct font, and securely attached.
