Volvo V40 MOT Failures
An analysis of 322,832 real DVSA MOT tests on the Volvo V40 — what fails, how often, and how that compares to every other car on UK roads. Generations covered: V40-1 (1996–2004), V40-2 (2012–2019).
Where the Volvo V40 fails its MOT
The single biggest MOT failure point on the Volvo V40 is emissions failure — this model is 316 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 322,832 MOT tests, 1.51% of all Volvo V40 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 (135x the fleet average), light unit fault (37x the fleet average), brake hoses perished or damaged (26x the fleet average), and steering rack wear (16x the fleet average). These ratios compare the Volvo V40'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 6 categories: Exhaust & Emissions, Suspension, Lights & Electrics, Brakes, Steering and others. If you're inspecting a Volvo V40 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 Volvo V40'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 Volvo V40 specifically, the DVSA data shows the most common failures at this mileage are emissions failure (316x the average) and suspension ball joints worn (135x). body panel damage (31x) and anti-roll bar links worn (27x) 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 Volvo V40 specifically, the DVSA data shows the most common failures at this mileage are suspension ball joints worn (78x the average) and emissions failure (63x). suspension joint dust cover severely deteriorated (28x) and steering rack wear (16x) 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 Volvo V40 specifically, the DVSA data shows the most common failures at this mileage are emissions failure (36x the average) and fuel pipe or hose damaged (32x). headlight fault (26x) and brake hoses perished or damaged (26x) also appear frequently.
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 Volvo V40 specialists and owners flag most frequently, drawn from manufacturer technical bulletins, workshop data, and verified owner reports.
Coil spring fracture (V40-2) Dangerous
The second-generation V40 suffers from premature coil spring fractures, particularly affecting the rear springs. Affects V40-2; typical independent garage repair cost is £200–£350.
Brake hose deterioration (V40-1) Dangerous
First-generation V40 models suffer from premature brake hose deterioration, with MOT failures at up to 24.3 times the national fleet average. Affects V40-1; typical independent garage repair cost is £100–£200.
DPF blockage and excessive smoke emission (V40-2) Major
This affects both the 1.6 and 2.0-litre diesel engines and occurs across all mileage ranges. Affects V40-2; typical independent garage repair cost is £300–£800.
Suspension joint and bush wear (V40-1) Major
The first-generation V40 shows exceptional wear rates in suspension bushes and joints, with MOT failures at up to 78 times the national fleet average. Affects V40-1; typical independent garage repair cost is £150–£400.

What to check before buying a Volvo V40
Based on the MOT failure data and known issues above, here's what to prioritise when inspecting a Volvo V40:
Exhaust & Emissions — check for emissions failure. Suspension — check for suspension ball joints worn, suspension joint dust cover severely deteriorated, anti-roll bar links worn. Lights & Electrics — check for light unit fault. Brakes — check for brake hoses perished or damaged.
Beyond the MOT items, ask specifically about coil spring fracture and brake hose deterioration. 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.
