Use our detailed year-by-year breakdown and failure analysis below to understand how your specific A4 Tdi Sport (115) is likely to perform.

Lamps, Reflectors and Electrical Equipment — 33.8% of failures

Lamps, Reflectors and Electrical Equipment issues account for 33.8% of MOT failures on the Audi A4 Tdi Sport (115). Lighting failures cover all external lights: headlights, tail lights, brake lights, indicators, fog lights, and reflectors. A single blown bulb will cause an MOT fail. This is one of the most preventable failure categories. Typical repair costs: £5–50. Pre-MOT check: Walk around the car and check every light — headlights (dipped and main beam), side lights, tail lights, brake lights, indicators, hazard lights, reverse light, rear fog light, and number plate lights. Replace any blown bulbs before the test.

Tyres — 21.3% of failures

Tyres issues account for 21.3% of MOT failures on the Audi A4 Tdi Sport (115). Tyre failures include tread depth below the legal minimum of 1.6mm, cuts, bulges, exposed cords, and incorrect tyre pressure. Tyres are one of the most common and easiest-to-prevent MOT failures. Typical repair costs: £50–200 per tyre. Pre-MOT check: Check tread depth with a 20p coin — if the outer band is visible, the tyre is too worn. Look for bulges, cuts, or embedded objects. Ensure all tyres match the recommended size and load rating.

Suspension — 21.3% of failures

Suspension issues account for 21.3% of MOT failures on the Audi A4 Tdi Sport (115). Suspension failures typically involve worn bushes, leaking shock absorbers, broken coil springs, and damaged suspension arms. These affect ride quality, tyre wear, and road holding. Typical repair costs: £200–500. Pre-MOT check: Look for uneven tyre wear, listen for clunking over bumps, and check if the car pulls to one side. A bouncy ride suggests worn shock absorbers. Visually inspect coil springs for cracks.
