Frequently asked.
- Why does smoke opacity levels exceed the manufacturer's… fail an MOT?
- Smoke opacity levels exceed the manufacturer's specified limit. Most commonly flagged on the Peugeot Premier. The DVSA's MOT standards require this item to meet minimum safety thresholds — when it falls short, the tester logs it as a Major or Dangerous defect and the car fails outright.
- How much does it cost to fix smoke opacity levels exceed the manufacturer's…?
- Costs vary depending on the vehicle, region, and severity. Use our MOT cost estimator for typical UK garage rates across the most common failure items.
