If you own or are considering buying a 2003 Audi S8, budget for potential repairs before each MOT. Before your MOT, pay particular attention to visibility: Check the windscreen for chips and cracks — damage larger than 10mm in the driver's swept area or 40mm elsewhere will fail. Test washers and wipers. Ensure both door mirrors are intact and adjustable. With an average mileage of 105,012 miles, these vehicles are in the higher-mileage bracket where wear-related failures become more common.
Visibility — 7.0% of failures
Visibility issues account for 7.0% of MOT failures on 2003 Audi S8 models. Visibility failures relate to the windscreen, wipers, washers, mirrors, and view-obstructing damage. Cracks in the windscreen swept area, ineffective wipers, or empty washer bottles are common causes. Typical repair costs: £10–300. Pre-MOT check: Check the windscreen for chips and cracks — damage larger than 10mm in the driver's swept area or 40mm elsewhere will fail. Test washers and wipers. Ensure both door mirrors are intact and adjustable.
Lamps, reflectors and electrical equipment — 3.5% of failures
Lamps, reflectors and electrical equipment issues account for 3.5% of MOT failures on 2003 Audi S8 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: £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.
Steering — 3.5% of failures
Steering issues account for 3.5% of MOT failures on 2003 Audi S8 models. Steering failures include excessive play in the steering wheel, leaking power steering fluid, worn track rod ends, and damaged steering rack. These affect vehicle control and are closely related to suspension wear. Typical repair costs: £150–600. Pre-MOT check: Check for excessive steering wheel play (more than a few inches of free movement). Listen for whining from the power steering pump. Look for fluid leaks under the car near the front wheels.
