Volkswagen Fox MOT Failures

An analysis of 708,661 real DVSA MOT tests on the Volkswagen Fox — what fails, how often, and how that compares to every other car on UK roads. Generations covered: 5Z (2005–2012).

Where the Volkswagen Fox fails its MOT

The single biggest MOT failure point on the Volkswagen Fox is power steering fault — this model is 156 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 708,661 MOT tests, 0.2% of all Volkswagen Fox tests recorded this as a failure.

Steering faults include worn track rod ends, power steering leaks, and rack wear. These are safety-critical — any play in the steering should be investigated immediately.

Other notable weak points include emissions failure (45x the fleet average), air leak causing a noticeable drop in pressure ... (228x the fleet average), anti-roll bar links worn (46x the fleet average), and body panel damage (62x the fleet average). These ratios compare the Volkswagen Fox'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: Steering, Exhaust & Emissions, Brakes, Suspension, Bodywork and others. If you're inspecting a Volkswagen Fox 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 Fox'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 Fox specifically, the DVSA data shows the most common failures at this mileage are air leak causing a noticeable drop in pressure ... (228x the average) and power steering fault (156x). body panel damage (62x) and anti-roll bar links worn (46x) 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 Fox specifically, the DVSA data shows the most common failures at this mileage are air leak causing a noticeable drop in pressure ... (44x the average) and power steering fault (22x). mandatory tell-tale for main beam headlamp or r... (16x) and anti-roll bar links worn (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 Volkswagen Fox specifically, the DVSA data shows the most common failures at this mileage are air leak causing a noticeable drop in pressure ... (34x the average) and power steering fault (20x). coil springs broken (13x) and fuel system leaking, or missing or ineffective ... (12x) 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 Volkswagen Fox specialists and owners flag most frequently, drawn from manufacturer technical bulletins, workshop data, and verified owner reports.

Power steering pipe corrosion and failure (5Z) Major

The power steering system pipes and hoses suffer from severe corrosion and deterioration at exceptionally high rates compared to other small cars. Affects 5Z; typical independent garage repair cost is £200–£400.

Exhaust emissions failures (5Z) Major

The Fox demonstrates exceptionally high rates of emissions test failures, with both specific induction/exhaust leaks (44.2 times fleet average) and general emissions level exceedances (40.8 times fleet average). Affects 5Z; typical independent garage repair cost is £200–£800.

Suspension joint excessive wear (5Z) Major

MOT data shows suspension pins, bushes and joints wearing at 30.8 times the fleet average, often following the earlier failure of protective dust covers. Affects 5Z; typical independent garage repair cost is £200–£500.

Suspension joint dust cover deterioration (5Z)

The rubber dust covers protecting suspension ball joints and bushes deteriorate at exceptionally high rates, with MOT failures up to 47.8 times the fleet average. Affects 5Z; typical independent garage repair cost is £150–£300.

What to check before buying a Volkswagen Fox

Based on the MOT failure data and known issues above, here's what to prioritise when inspecting a Volkswagen Fox:

Steering — check for power steering fault. Exhaust & Emissions — check for emissions failure. Brakes — check for air leak causing a noticeable drop in pressure ..., coil springs broken. Suspension — check for anti-roll bar links worn.

Beyond the MOT items, ask specifically about power steering pipe corrosion and failure and exhaust emissions failures. 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.
