Top issues to watch for

The most serious Volkswagen Up problems ranked by severity. We track 5 known issues — here are the ones you need to know about first.

Major
Brake actuator leakage
AA, AA22012–202440k–120k miles
The Up experiences brake actuator leaks at up to 10.5 times the fleet average, particularly on higher-mileage examples. This affects the hydraulic brake system components and can progress from minor seepage to performance-affecting leaks. The trend is worsening across recent MOT test years, suggesting this is an emerging durability issue.
What happens if ignoredBrake actuator leaks can progress from minor seepage to significant performance reduction. In severe cases, braking effectiveness is compromised, creating a safety risk. Early detection allows for cost-effective repair before complete actuator replacement is needed.

Major
Brake pedal travel excessive
AA, AA22012–202420k–150k miles
The Up fails MOT tests for insufficient brake pedal reserve travel at 9.9 times the fleet average, with the highest failure rate on cars over 120,000 miles. This indicates wear in the brake system causing the pedal to travel too far before effective braking begins. The trend is worsening, suggesting this develops as a common age-related issue on this platform.
What happens if ignoredExcessive brake pedal travel reduces braking confidence and effectiveness. This typically indicates worn brake components, air in the system, or hydraulic problems. Without repair, braking performance will continue to deteriorate and the car will fail MOT tests.

Minor
Fuel filler cap and fuel system leaks
AA, AA22012–20240k–150k miles
The Up shows an exceptionally high rate of fuel system leaks and filler cap issues, failing MOT tests at 28.4 times the national fleet average. This covers leaking fuel lines, ineffective filler cap seals, and fuel tank ventilation problems. The issue affects cars across all mileage ranges from new to high-mileage examples, suggesting a design weakness rather than age-related deterioration.
What happens if ignoredFuel leaks present a fire risk and will cause MOT failure. Small leaks may initially appear as advisories but typically worsen over time. Filler cap replacement is inexpensive but fuel line repairs can be more costly and require specialist attention.

Minor
Emissions system deterioration
AA, AA22012–20240k–150k miles
The Up shows elevated emissions failures at up to This occurs across all mileage ranges including relatively new cars, with a worsening trend in recent years. The pattern suggests issues with the emissions control system components rather than simple catalyst deterioration.
What happens if ignoredEmissions failures will prevent MOT passes and may indicate developing engine problems. Simple issues like faulty lambda sensors or spark plugs are relatively inexpensive to fix. More complex problems affecting the catalytic converter or engine management system can be costlier to resolve.
