2004 Mercedes-Benz Vito — MOT failures & pass rate
7,796 MOT tests on the 2004 Mercedes-Benz Vito are in this dataset, and 68.2% of them passed. Vans of a similar age fail 29.9% of the time, so this is 1.9pp worse than the group it competes with. Failures cluster in lighting & signalling, suspension and brakes.
What the MOT record shows
One area stands out: lighting & signalling, recorded in 21.7% of tests against 18.4% for the next-worst category.
At component level the recurring items are component mounting prescribed areas, integral vehicle structure condition and headlamp aim — component mounting prescribed areas alone was recorded 1,753 times.
A 150k+ example is materially riskier than a 0-30k one: 31.4% versus 35.9%.
Brakes is the most common advisory, noted on 43.4% of tests — work that passed today but is likely due soon.

What to check before buying a 2004 Vito
The failure pattern for this year is specific enough to inspect against: lighting & signalling accounted for 21.7% of tests. Start there.
- Lighting & signalling (21.7% of tests): Often a cheap bulb, but persistent issues can mean wiring or corrosion in the units. Typical repair: £10–£150.
- Suspension (18.4% of tests): Worn drop links, bushes, springs or shocks — listen for knocks over bumps and check for uneven tyre wear. Typical repair: £150–£450 per corner.
- Brakes (14.7% of tests): Pads/discs are routine wear; binding, imbalance or corroded pipes are more serious — test for pulling under braking. Typical repair: £100–£350 per axle.
Repair costs are rough UK ballpark ranges to set expectations, not quotes — actual prices vary widely by car, parts and garage.
