Audi Rs4 Avant MOT Failures
An analysis of 454 real DVSA MOT tests on the Audi Rs4 Avant — what fails, how often, and how that compares to every other car on UK roads.
Where the Audi Rs4 Avant fails its MOT
The single biggest MOT failure point on the Audi Rs4 Avant is brake hoses perished or damaged — this model is 5.8 times more likely to fail on this item than the average car on UK roads. That makes it worth watching for anyone buying or owning this model. Across 454 MOT tests, 11% of all Audi Rs4 Avant tests recorded this as a failure.
Brake failures on the MOT range from worn pads and discs (routine maintenance) to corroded brake lines and seized calipers (more serious). Check for any pulling under braking and listen for grinding.
Other notable weak points include suspension joint dust cover missing or no longe... (16x the fleet average) and suspension joint dust cover severely deteriorated (9.1x the fleet average). These ratios compare the Audi Rs4 Avant'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 2 categories: Brakes, Suspension. If you're inspecting a Audi Rs4 Avant 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 Audi Rs4 Avant'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.
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 Audi Rs4 Avant specifically, the DVSA data shows the most common failures at this mileage are suspension joint dust cover missing or no longe... (16x the average) and suspension joint dust cover severely deteriorated (9.1x). brake hoses perished or damaged (5.5x) and brake hoses perished or damaged 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.
The standout failure at this mileage is brake hoses perished or damaged at 5.8x the fleet average.
The shift from suspension joint dust cover missing or no longe... at lower mileages to brake hoses perished or damaged 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.
