Renault Megane Scenic MOT Failures
An analysis of 98,802 real DVSA MOT tests on the Renault Megane Scenic — what fails, how often, and how that compares to every other car on UK roads.
Where the Renault Megane Scenic fails its MOT
The single biggest MOT failure point on the Renault Megane Scenic is indicator or hazard warning switch inoperative — this model is 196 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 98,802 MOT tests, 5.26% of all Renault Megane Scenic 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 anti-roll bar links worn (169x the fleet average), power steering fault (27x the fleet average), indicator or hazard warning switch does not ope... (159x the fleet average), and rear fog lamp adversely affected by the operati... (74x the fleet average). These ratios compare the Renault Megane Scenic'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 4 categories: Lights & Electrics, Suspension, Steering, Exhaust & Emissions. If you're inspecting a Renault Megane Scenic 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 Megane Scenic'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 Megane Scenic specifically, the DVSA data shows the most common failures at this mileage are indicator or hazard warning switch inoperative (196x the average) and indicator or hazard warning switch does not ope... (159x). anti-roll bar links worn (87x) and abs fault (48x) 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 Megane Scenic specifically, the DVSA data shows the most common failures at this mileage are anti-roll bar links worn (169x the average) and abs fault (60x). indicator or hazard warning switch does not ope... (59x) and indicator or hazard warning switch inoperative (48x) 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 Megane Scenic specifically, the DVSA data shows the most common failures at this mileage are rear fog lamp adversely affected by the operati... (74x the average) and any part of the noise suppression system insecure (37x). power steering fault (27x) and indicator or hazard warning switch inoperative (23x) also appear frequently.
The shift from indicator or hazard warning switch inoperative at lower mileages to rear fog lamp adversely affected by the operati... 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.
What to check before buying a Renault Megane Scenic
Based on the MOT failure data and known issues above, here's what to prioritise when inspecting a Renault Megane Scenic:
Lights & Electrics — check for indicator or hazard warning switch inoperative, indicator or hazard warning switch does not ope..., rear fog lamp adversely affected by the operati.... Suspension — check for anti-roll bar links worn, abs fault, suspension pin, bush or joint worn. Steering — check for power steering fault.
Always check the car's full MOT history for patterns — recurring advisories often become failures within 12 months. Enter any reg into our free car check to see the complete picture.
