Common initial failure categories

These are the items that most often caused a Mercedes-Benz EQC 400 AMG Line Premium + 4M to fail its first test, with what each one usually means for a buyer.

• Condition — 15.9% of tests. Corrosion, damage or wear on a tested component. Worth seeing in person, as the cost ranges from trivial to structural.
• Wipers — 1.3% of tests. Worn wiper blades. Minutes to fix, and a fair hint that servicing was skipped.
• Suspension Arms — 1.3% of tests. Worn arms or bushes. A common age-related repair that affects handling and tyre wear.
• Headlamp Aim — 0.9% of tests. Headlights pointing too high or low. Cheap to adjust, and common on every make.
• Registration Plates — 0.8% of tests. A damaged, dirty or non-compliant number plate.
• Tread Depth — 0.6% of tests. Tyres below the 1.6mm legal limit. Budget for tyres, and treat it as a sign of how the car was maintained.

What this does and does not tell you

A pass rate describes how a population of cars behaved on test day. It says nothing about how one car was driven, serviced or repaired, and an MOT does not cover the engine, clutch or gearbox at all.

Use it to know what to look for: if tyres and brakes dominate the list, price those in; if corrosion or suspension appears, get underneath the car. Then check the individual vehicle — its MOT history shows whether these same items have been advised year after year, and its mileage record shows whether the reading is consistent.
