What Audi A8 Owners Should Watch For

Based on the MOT test data for the Audi A8, here are the key areas to pay attention to before your MOT:

Tyres (2.1% failure risk) — Ensure all tyres have at least 1.6mm tread depth across the central three-quarters. Check for sidewall damage, bulges, and uneven wear.
Lamps & Electrics (1.9% failure risk) — Walk around the car and check every bulb — headlights, brake lights, indicators, fog lights, and number plate lights. This is one of the cheapest and easiest fixes.
Brakes (1.4% failure risk) — Check brake pad thickness, disc condition, and handbrake operation. Listen for grinding or squealing when braking.

Many of these issues are inexpensive to fix when caught early. A pre-MOT inspection at a local garage typically costs £20–£40 and can save you the cost of a retest (£15–£30) plus the inconvenience of a failed MOT.
