Mercedes Benz V MOT Failures
An analysis of 53,908 real DVSA MOT tests on the Mercedes Benz V — what fails, how often, and how that compares to every other car on UK roads.
Where the Mercedes Benz V fails its MOT
The single biggest MOT failure point on the Mercedes Benz V is parking brake inefficient — this model is 108 times more likely to fail on this item than the average car on UK roads. That makes it an extreme outlier for anyone buying or owning this model. Across 53,908 MOT tests, 0.46% of all Mercedes Benz V tests recorded this as a failure.
Brake failures on the MOT range from worn pads and discs (routine maintenance) to corroded brake lines and seized calipers (more serious). Check for any pulling under braking and listen for grinding.
Other notable weak points include abs fault (44x the fleet average), structural corrosion (104x the fleet average), vehicle structure corroded to the extent that t... (122x the fleet average), and tyre wear or damage (18x the fleet average). These ratios compare the Mercedes Benz V's failure rate on each item against the national average for all cars tested — a ratio of 10x means this model fails ten times more often than a typical car.
The failures span 5 categories: Brakes, Suspension, Bodywork, Tyres, Lights & Electrics. If you're inspecting a Mercedes Benz V before purchase, these are the areas to focus on — and if any have been flagged as advisories on a previous MOT, they're likely to become failures in the near future.
How failures change with mileage
The Mercedes Benz V's weak points shift as the car covers more miles. Understanding these patterns helps you know what to expect — and what to budget for — at each stage of ownership.
Under 60,000 miles
At this mileage, most failures are either design-related or caused by age rather than wear. Components like bushes and drop links may not have been replaced yet, and original-fit parts can deteriorate even on low-mileage cars that spend a lot of time sitting.
For the Mercedes Benz V specifically, the DVSA data shows the most common failures at this mileage are vehicle structure corroded to the extent that t... (122x the average) and structural corrosion (104x). anti-roll bar links worn (102x) and parking brake inefficient (76x) also appear frequently.
60,000 to 100,000 miles
This is where routine wear items start to show up. Brake components, tyres, and exhaust parts have done serious work by this point. Cars that have been well serviced will show fewer of these failures — this mileage band is where good maintenance really separates the well-kept from the neglected.
For the Mercedes Benz V specifically, the DVSA data shows the most common failures at this mileage are parking brake inefficient (44x the average) and structural corrosion (29x). abs fault (9.2x) and transmission shaft constant velocity joint boot... (6.5x) also appear frequently.
Over 100,000 miles
High-mileage cars accumulate failures across multiple systems. The key question isn't whether things will need doing — they will — but whether the car has been maintained well enough to keep on top of them. Look for a consistent service history and recent MOT passes with minimal advisories.
For the Mercedes Benz V specifically, the DVSA data shows the most common failures at this mileage are emissions failure (39x the average) and parking brake inefficient (37x). towbar fault (23x) and tyre wear or damage (18x) also appear frequently.
The shift from vehicle structure corroded to the extent that t... at lower mileages to emissions failure at higher mileages is typical — early failures tend to be design or factory-related, while high-mileage failures reflect accumulated mechanical wear. A car that's been well maintained will usually dodge the worst of both.
What to check before buying a Mercedes Benz V
Based on the MOT failure data and known issues above, here's what to prioritise when inspecting a Mercedes Benz V:
Brakes — check for parking brake inefficient, parking brake efficiency less than 50% of the r.... Suspension — check for abs fault, subframe bushes or mounts worn. Bodywork — check for structural corrosion, vehicle structure corroded to the extent that t....
