What Is the Bmw 420 MOT Pass Rate?
on 23 April 2026
The latest figures from the DVSA (Driver and Vehicle Standards Agency) show that the BMW 420 has a pass rate of 86.8% based on over 59,830 tests conducted nationwide. This figure is significantly higher than the national average MOT pass rate of 79.6%. The Bmw 420's strong performance suggests that this model typically meets or exceeds the standards set by the DVSA for roadworthiness and safety.
Despite its high pass rate, you should note that a notable 13.2% of vehicles still fail their MOT tests, indicating areas where owners might need to pay more attention during regular maintenance checks.

Common Bmw 420 MOT Failures
While the Bmw 420 generally performs well in its annual MOT test, there are specific issues that commonly lead to failures:
Electrical System Issues
Electrical faults often rank high among the reasons for failure. These include faulty bulbs, malfunctioning indicators, and issues with warning lights or dashboard components.
Braking Problems
Faults related to braking systems can also be significant contributors to MOT test failures. This includes problems such as worn brake pads or discs, leaks in hydraulic lines, or issues with handbrakes not engaging properly.
Exhaust and Emissions
Issues with the exhaust system, catalytic converter, and emission control devices often result in failure too. Leaks, damage, or non-compliance with emissions regulations can lead to a failed MOT test for your Bmw 420.
Tyres
Worn tyres, incorrect tyre pressures, and inadequate tread depth are common causes of MOT failures. Regular checks should be carried out to ensure that tyres meet the legal standards before heading to an MOT centre.
Owners of BMW 420 models can help prevent these issues by conducting pre-MOT inspections focusing on electrical systems, braking components, exhaust integrity, and tyre condition. By addressing these areas in advance, you may avoid a failed MOT test and reduce repair costs associated with sudden failures during the official inspection process.
Bmw 420 Mileage and Reliability
The average mileage at which BMW 420 models undergo their first MOT is approximately 65,988 miles. This figure gives us insight into typical ownership patterns and suggests that many Bmw 420s remain in good condition until they reach this milestone.
However, the high incidence of specific failures indicates that maintaining regular service schedules and addressing minor issues promptly can help prolong a vehicle's reliability and improve its chances of passing future MOT tests. Regular servicing at recommended intervals helps ensure that critical systems such as brakes, electrical components, and exhausts remain in optimal condition well beyond 65,000 miles.
Ownership Patterns
The fact that the average Bmw 420 is around 65,988 miles when it first undergoes its MOT suggests a pattern where many owners keep these vehicles for several years before selling or trading them. This longevity speaks to the reliability and build quality of the BMW 420 model.
PCP/HP Financed Vehicles
if you own a Bmw 420 that was financed through Personal Contract Purchase (PCP) or Hire Purchase (HP), your vehicle may be eligible for redress under the Financial Conduct Authority's (FCA) Redress Scheme. This scheme aims to provide compensation to affected consumers who experienced issues with their PCP/HP vehicles, including potential MOT failures.
In summary, while the Bmw 420 boasts a commendable MOT pass rate of 86.8%, maintaining regular maintenance and addressing common failure points such as electrical systems, braking components, exhaust integrity, and tyre condition can help ensure your vehicle remains in optimal working order well beyond its initial mileage at first MOT test.
