Volkswagen Transporter MOT Failures
An analysis of 152,282 real DVSA MOT tests on the Volkswagen Transporter — what fails, how often, and how that compares to every other car on UK roads. Generations covered: T4 (1990–2003), T5 (2003–2015), T6 (2015–2024).
Where the Volkswagen Transporter fails its MOT
The single biggest MOT failure point on the Volkswagen Transporter is emissions failure — this model is 425 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 152,282 MOT tests, 4.63% of all Volkswagen Transporter tests recorded this as a failure.
Exhaust and emissions failures often point to catalytic converter degradation, lambda sensor faults, or — in diesel models — DPF problems. These can be expensive to fix and will cause an immediate MOT failure.
Other notable weak points include suspension ball joints worn (201x the fleet average), abs fault (544x the fleet average), fuel system leaking, or missing or ineffective ... (121x the fleet average), and structural corrosion (109x the fleet average). These ratios compare the Volkswagen Transporter'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: Exhaust & Emissions, Suspension, Bodywork, Brakes, Steering. If you're inspecting a Volkswagen Transporter 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 Volkswagen Transporter'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 Volkswagen Transporter specifically, the DVSA data shows the most common failures at this mileage are free play in the steering, measured at the rim ... (894x the average) and abs fault (544x). suspension ball joints worn (201x) and emissions failure (192x) 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 Volkswagen Transporter specifically, the DVSA data shows the most common failures at this mileage are emissions failure (358x the average) and brake hoses perished or damaged (189x). headlight fault (139x) and fuel system leaking, or missing or ineffective ... (121x) 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 Volkswagen Transporter specifically, the DVSA data shows the most common failures at this mileage are emissions failure (246x the average) and indicator or hazard warning switch does not ope... (80x). mandatory tell-tale for main beam headlamp or r... (79x) and coil springs broken (52x) also appear frequently.
The shift from free play in the steering, measured at the rim ... 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.
Known issues beyond the MOT
An MOT only tests roadworthiness at a single point in time — it won't catch developing faults, intermittent problems, or issues that haven't yet reached the failure threshold. These are the issues that Volkswagen Transporter specialists and owners flag most frequently, drawn from manufacturer technical bulletins, workshop data, and verified owner reports.
Structural corrosion at mounting points Dangerous
The Transporter's commercial duty cycle and exposure to road salt causes severe corrosion at subframe mounting points, suspension attachment areas, and load-bearing chassis sections. Affects T4, T5, T6; typical independent garage repair cost is £200–£2,000.
Suspension component wear Major
Commercial loading and frequent stop-start driving accelerates wear of suspension bushes, ball joints, and anti-roll bar links. Affects T4, T5, T6; typical independent garage repair cost is £150–£400.
Wheel bearing failure Major
Heavy commercial loading and frequent starting from rest puts exceptional stress on wheel bearings. Affects T4, T5, T6; typical independent garage repair cost is £120–£250.
Emissions system failure (petrol) Major
Petrol Transporters suffer severe emissions control failures due to the commercial duty cycle and age of the engine management systems. Affects T4, T5; typical independent garage repair cost is £200–£1,200.

What to check before buying a Volkswagen Transporter
Based on the MOT failure data and known issues above, here's what to prioritise when inspecting a Volkswagen Transporter:
Exhaust & Emissions — check for emissions failure. Suspension — check for suspension ball joints worn, abs fault, wheel bearings worn. Bodywork — check for fuel system leaking, or missing or ineffective ..., structural corrosion.
Beyond the MOT items, ask specifically about structural corrosion at mounting points and suspension component wear. These won't show up on a standard MOT but can be expensive to fix — repairs start from £200. A specialist pre-purchase inspection is worth the investment on this model.
Always check the car's full MOT history for patterns — recurring advisories often become failures within 12 months. And verify the service history to confirm maintenance has been kept up to schedule. Enter any reg into our free car check to see the complete picture.
