2006 Peugeot 407 2.0L Diesel · KB06 NHJ

The most recent MOT test for this 2006 Peugeot 407, conducted on 11 April 2022, resulted in a failure with no recorded defects. This is a critical omission in the record, as a failed MOT without explanation leaves the vehicle’s condition entirely unaccounted for. The absence of any subsequent tests—nearly four years later—raises immediate concerns about whether the car was ever repaired or whether the failure was deliberately ignored. The lack of a passing test since then means no official verification of structural integrity, emissions compliance, or major mechanical systems like brakes, suspension, or steering has been documented. Buyers should treat this as a significant red flag, as even minor unresolved issues can escalate into costly failures over time. The recorded mileage of 157,713 miles suggests average annual usage for a vehicle of this age, with roughly 7,886 miles per year over its lifetime. However, the sparse MOT history—just a single test in 2022—creates uncertainty about whether the car was driven consistently or left unused for extended periods. Long periods off the road can accelerate corrosion, degrade fluids, and weaken rubber components like suspension bushes and wiper blades. Without intermediate tests, there’s no way to confirm whether the vehicle was maintained during gaps in service, particularly after the 2022 failure. The lack of mileage progression in the record further complicates assessment, as it’s impossible to determine if the car was driven lightly or if critical components were neglected. Given the failed MOT and the absence of subsequent testing, a buyer should prioritise an independent inspection of high-wear areas that often fail without warning. The suspension—particularly coil springs, bushes, and shock absorbers—should be checked for uneven wear or leaks, as these components degrade gradually and can compromise handling and ride quality. Brakes warrant close scrutiny: binding calipers, unevenly worn discs, or corroded flexi-hoses can develop silently, and the 2022 failure suggests past issues may recur. Structural corrosion, especially around wheel arches, sills, and the subframe, is another concern for a vehicle this age, particularly if it was driven in salted or coastal environments. Exhaust emissions systems, including the catalytic converter and oxygen sensors, should also be tested, as these are common failure points for older petrol engines. Finally, fluid levels—brake fluid, power steering, and engine oil—should be verified, as prolonged neglect can lead to catastrophic failures. The failure to pass the 2022 test alone justifies a thorough mechanical review before any purchase.
