About This Data
The 2004 Mazda Bongo has an MOT pass rate of 59.2% based on 4,089 tests — slightly below the UK average for UK vehicles. Cars of this vintage present for MOT with an average of 124,890 miles on the odometer. With a 40.8% failure rate, the 2004 Bongo is rated as "Below Average" for MOT reliability.
If you own or are considering buying a 2004 Mazda Bongo, budget for potential repairs before each MOT. 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 124,890 miles, these vehicles are in the higher-mileage bracket where wear-related failures become more common.
Suspension — 9.6% of failures
Suspension issues account for 9.6% of MOT failures on 2004 Mazda Bongo 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: £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.
Body, chassis, structure — 6.2% of failures
Body, chassis, structure issues account for 6.2% of MOT failures on 2004 Mazda Bongo models. Body and structure failures include excessive corrosion, sharp edges, loose panels, and damage to the vehicle frame. Rust is the primary concern, especially on older vehicles or those exposed to road salt. Typical repair costs: £100–500+. Pre-MOT check: Inspect sills, wheel arches, door bottoms, and the chassis for rust. Surface rust is acceptable but structural corrosion or holes will fail. Check that all doors, bonnet, and boot close securely.
Lamps, reflectors and electrical equipment — 5.5% of failures
Lamps, reflectors and electrical equipment issues account for 5.5% of MOT failures on 2004 Mazda Bongo 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.
