How failures change with mileage
The Renault Master Mm35 Business Dci'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.
The standout failure at this mileage is emissions failure at 20x the fleet average.
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 Master Mm35 Business Dci specifically, the DVSA data shows the most common failures at this mileage are brake pedal anti-slip provision missing, loose ... (33x the average) and emissions failure (10x).
The shift from emissions failure at lower mileages to brake pedal anti-slip provision missing, loose ... 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.
