Renault Modus MOT Failures
An analysis of 269,767 real DVSA MOT tests on the Renault Modus — what fails, how often, and how that compares to every other car on UK roads. Generations covered: Mk1 (2004–2012).
Where the Renault Modus fails its MOT
The single biggest MOT failure point on the Renault Modus is emissions failure — this model is 114 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 269,767 MOT tests, 1.7% of all Renault Modus 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 seat mounting fault (23x the fleet average), light unit fault (93x the fleet average), stop lamp adversely affected by the operation o... (60x the fleet average), and body panel damage (45x the fleet average). These ratios compare the Renault Modus'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, Seatbelts & Airbags, Lights & Electrics, Bodywork, Suspension. If you're inspecting a Renault Modus 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 Renault Modus'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 Renault Modus specifically, the DVSA data shows the most common failures at this mileage are suspension component damaged or corroded (115x the average) and emissions failure (114x). rear fog lamp adversely affected by the operati... (71x) and stop lamp adversely affected by the operation o... (60x) 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 Renault Modus specifically, the DVSA data shows the most common failures at this mileage are headlight fault (156x the average) and light unit fault (93x). emissions failure (58x) and body panel damage (25x) 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 Renault Modus specifically, the DVSA data shows the most common failures at this mileage are body panel damage (26x the average) and light unit fault (24x). seat mounting fault (21x) and stop lamp adversely affected by the operation o... (17x) also appear frequently.
The shift from suspension component damaged or corroded at lower mileages to body panel damage 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 Renault Modus specialists and owners flag most frequently, drawn from manufacturer technical bulletins, workshop data, and verified owner reports.
Coil spring fracture Dangerous
The Modus suffers from coil spring failures at a rate 26.7 times higher than the national fleet average, with over 12,000 documented MOT failures across all engine variants. Affects Mk1; typical independent garage repair cost is £200–£400.
Steering ball joint wear Dangerous
Ball joint failures occur at 39 times the national fleet average with over 10,600 documented MOT failures across all variants. Affects Mk1; typical independent garage repair cost is £150–£350.
Structural corrosion Dangerous
MOT data shows 376 documented structural failures where corrosion has reduced assembly rigidity to dangerous levels. Affects Mk1; typical independent garage repair cost is £800–£3,000.
Excessive smoke emission (Mk1 Diesel) Major
The 1.5 dCi diesel engine suffers from severe smoke emission problems, failing MOT smoke opacity tests at rates up to 96.8 times higher than the national fleet average. Affects Mk1; typical independent garage repair cost is £300–£2,000.

What to check before buying a Renault Modus
Based on the MOT failure data and known issues above, here's what to prioritise when inspecting a Renault Modus:
Exhaust & Emissions — check for emissions failure. Seatbelts & Airbags — check for seat mounting fault. Lights & Electrics — check for light unit fault, stop lamp adversely affected by the operation o..., headlight fault.
Beyond the MOT items, ask specifically about coil spring fracture and steering ball joint 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.

Renault Modus MOT FAQs
What are the most common MOT failures on a Renault Modus?
Based on 269,767 DVSA MOT tests, the most common failure is emissions failure — at 114x the national fleet average. Other frequent failures include seat mounting fault and light unit fault.
Is the Renault Modus reliable based on MOT data?
The Renault Modus has 19 MOT failure categories above the fleet average. Specialists also flag coil spring fracture as a concern. A pre-purchase inspection and service history check are recommended.
What MOT failures should I expect at high mileage?
Above 100,000 miles, the Renault Modus most commonly fails on body panel damage and light unit fault. Under 60,000 miles, the main issues are suspension component damaged or corroded and emissions failure.
