2012 Mercedes-Benz Sprinter 2.1L Diesel · KW12 AAN

The 2012 Mercedes-Benz Sprinter’s most recent MOT tests, conducted on July 3, 2025 , reveal a concerning pattern of two consecutive failures despite identical mileage (310,692 miles). The absence of recorded defects in either test suggests the failures were likely procedural—potentially due to administrative errors, expired test centre licences, or a temporary DVSA system glitch rather than mechanical issues. However, the lack of a valid MOT for over a year (from March 2022 ) raises immediate red flags. The vehicle has not undergone a proper roadworthiness assessment since March 7, 2022 , when it was tested at 481,564 miles —a mileage now surpassed by 70,872 miles . This gap means critical components like brakes, suspension, and emissions systems could have deteriorated significantly without official verification. The recorded mileage of 310,692 miles at the latest tests indicates an average of 22,192 miles per year over the past decade, which is unusually high for a vehicle of this age. Comparing this to the 481,564-mile mark in 2022 , the vehicle accumulated 70,872 miles in just three years —a rate suggesting either intensive commercial use or prolonged periods of neglect. The absence of any MOT failures between 2022 and 2025 does not imply consistent maintenance; rather, it may reflect sporadic servicing or the deferral of obvious wear. The 14-month gap between the 2022 and 2025 tests —despite the vehicle’s age and mileage—is particularly concerning, as it implies the owner may have avoided regular inspections or prioritised cost over safety. Given the lack of defects in the failed tests, a buyer should prioritise an independent inspection of high-wear components that are not always flagged in standard MOTs. Key areas to examine include rear brake binding (a common issue in Sprinters with high mileage), suspension bush deterioration (especially rear trailing arms and control arms), and coil spring fatigue —all of which can develop silently over 310,000+ miles . The exhaust system should be checked for leaks or corrosion, particularly around the catalytic converter and oxygen sensors, as these often fail intermittently without showing in MOT tests. Additionally, structural corrosion in the chassis or subframe—common in Sprinters exposed to salt or poor storage—must be assessed, as this can compromise safety without immediate failure. The emissions system (DPF, if applicable) warrants scrutiny, as repeated failures here could indicate improper driving habits or maintenance lapses. Finally, the tyre tread depth and wheel alignment should be verified, as the high mileage suggests uneven wear may have occurred.
