Volvo C70 MOT Failures
An analysis of 51,385 real DVSA MOT tests on the Volvo C70 — what fails, how often, and how that compares to every other car on UK roads. Generations covered: C70-I (1996–2005), C70-II (2006–2013).
Where the Volvo C70 fails its MOT
The single biggest MOT failure point on the Volvo C70 is light unit fault — this model is 29 times more likely to fail on this item than the average car on UK roads. That makes it a significant weak point for anyone buying or owning this model. Across 51,385 MOT tests, 5.6% of all Volvo C70 tests recorded this as a failure.
Lighting faults are usually straightforward to fix (bulbs, connectors, earth points) but can indicate deeper wiring issues on older cars. Check all lights including fog lamps, number plate lights, and dashboard warning lights.
Other notable weak points include steering rack wear (73x the fleet average), headlight fault (48x the fleet average), emissions failure (46x the fleet average), and power steering fault (25x the fleet average). These ratios compare the Volvo C70'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: Lights & Electrics, Steering, Exhaust & Emissions, Tyres, Suspension. If you're inspecting a Volvo C70 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 C70'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 C70 specifically, the DVSA data shows the most common failures at this mileage are steering rack wear (73x the average) and emissions failure (46x). suspension joint dust cover severely deteriorated (45x) and power steering fault (25x) 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 C70 specifically, the DVSA data shows the most common failures at this mileage are coil springs broken (155x the average) and tyre fouling a part of the vehicle (50x). headlight fault (48x) and light unit fault (21x) 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 C70 specifically, the DVSA data shows the most common failures at this mileage are tyre fouling a part of the vehicle (35x the average) and headlight fault (27x). light unit fault (14x) and engine mounting/bracket severely damaged or det... (11x) also appear frequently.
The shift from steering rack wear at lower mileages to tyre fouling a part of the vehicle 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 Volvo C70 specialists and owners flag most frequently, drawn from manufacturer technical bulletins, workshop data, and verified owner reports.
Suspension component excessive wear Major
MOT data shows C70 models fail at 14.9x the fleet average for excessive wear in suspension pins, bushings, and joints. Affects C70-I, C70-II; typical independent garage repair cost is £150–£400.
Power steering system malfunction Major
C70 petrol models show MOT failure rates of 16.0x the fleet average for power steering fluid leaks and system malfunctions. Affects C70-I, C70-II; typical independent garage repair cost is £300–£600.
Brake hose deterioration Major
MOT data shows C70 models fail at 12.1x the fleet average for flexible brake hose damage and deterioration. Affects C70-I, C70-II; typical independent garage repair cost is £80–£200.
Diesel particulate filter blockage (C70-II) Major
Second generation C70 diesel models suffer from DPF blockage issues, with MOT data showing The DPF system requires regular high-speed driving to burn off accumulated soot. Affects C70-II; typical independent garage repair cost is £400–£800.

What to check before buying a Volvo C70
Based on the MOT failure data and known issues above, here's what to prioritise when inspecting a Volvo C70:
Lights & Electrics — check for light unit fault, headlight fault, electrical wiring fault. Steering — check for steering rack wear, power steering fault. Exhaust & Emissions — check for emissions failure.
Beyond the MOT items, ask specifically about suspension component excessive wear and power steering system malfunction. These won't show up on a standard MOT but can be expensive to fix — repairs start from £150. 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.
