About This Data

The 1998 Audi A4 1.8 has an MOT pass rate of 42.9% based on 2,265 tests โ€” significantly below the UK average for UK vehicles. Cars of this vintage present for MOT with an average of 130,892 miles on the odometer. With a 57.1% failure rate, the 1998 A4 1.8 is rated as "Very Poor" for MOT reliability.

If you own or are considering buying a 1998 Audi A4 1.8, be prepared for above-average maintenance costs. Before your MOT, pay particular attention to suspension: 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. With an average mileage of 130,892 miles, these vehicles are in the higher-mileage bracket where wear-related failures become more common.

Suspension โ€” 2.4% of failures

Suspension issues account for 2.4% of MOT failures on 1998 Audi A4 1.8 models. 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: ยฃ200โ€“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.

Lamps, Reflectors and Electrical Equipment โ€” 1.4% of failures

Lamps, Reflectors and Electrical Equipment issues account for 1.4% of MOT failures on 1998 Audi A4 1.8 models. 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: ยฃ5โ€“50. Pre-MOT check: Walk around the car and check every light โ€” 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 โ€” 1.1% of failures

Tyres issues account for 1.1% of MOT failures on 1998 Audi A4 1.8 models. 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: ยฃ50โ€“200 per tyre. Pre-MOT check: Check tread depth with a 20p coin โ€” 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.
