2007 Mercedes-Benz CLS 3.0L Diesel · LM56 CNN

A largely unblemished MOT record across nineteen years and over 165,000 miles is the defining mechanical story of this Mercedes-Benz CLS, with no advisories or component defects ever captured in the DVSA history. The April 2026 test outcome on 2026-04-10 returned a fail with no defects recorded, a notable but isolated entry that warrants clarification with the vendor, as the official database lists no specific reason for the refusal. The previous four tests between 2023 and 2025 were clean passes with no advisories, including a 2024-02-13 pass and a 2025-04-01 pass that immediately followed an earlier 2025-04-01 fail which itself carried no listed defects. Because the DVSA data is sparse on detail, a prospective buyer should obtain the actual failure sheets (VT30 or VT32) from the testing station to understand whether the 2026 failure related to emissions, lighting, brakes, or structural items, and whether any rectification work has since been evidenced by a further pass. Annual mileage of roughly 8,727 over the vehicle's nineteen-year life sits comfortably within the typical band for a car of this age, suggesting consistent road use rather than extended periods of storage or only occasional running. There are no obvious gaps in annual testing that would indicate the vehicle was laid up for multiple consecutive years, and the mileage accumulation appears steady across the recorded MOT events. Mechanically, this kind of regular usage tends to keep seals, gaskets, and brake components exercised rather than allowing corrosion to take hold on static brake discs or fuel lines, although a high overall odometer reading of 165,808 does mean wear-related items such as suspension bushes, coil springs, dampers, and exhaust mounting rubbers will have accumulated considerable fatigue cycles. Given the absence of recorded advisories, a physical inspection should focus on the components most prone to wear on a high-mileage Mercedes of this generation. Pay particular attention to the front suspension arms, control arm bushes, and anti-roll bar drop links, as worn bushes typically produce clonking or knocking noises over speed humps and uneven tarmac. The ABC (Active Body Control) hydraulic system, where fitted, should be checked for any fluid seepage around the rams and the pump reservoir, as well as for the characteristic sagging at standstill that indicates failing spheres or accumulator pressure loss. Steering should feel precise without vagueness at the straight-ahead or clonking through the rack mounting, and any wandering on a motorway run could point to worn rear trailing arm bushes, a known weakness on this chassis. Brake feel on the test drive should be firm and progressive without judder under heavy deceleration, which on a car of this mileage would suggest warped front discs rather than pad wear, and the calipers should release cleanly without any residual binding that can lead to uneven disc corrosion. Listen on cold start for any timing chain rattle from the M272 or M273 petrol V6 and V8 engines, as these units are known for balance shaft and idler gear wear at high mileages, and inspect the underside for any signs of oil misting around the cam covers, sump, and rear main seal area. Exhaust mounting rubbers, heat shields, and the rear silencer box should be checked for security and corrosion, and a thorough road test on a stretch of dual carriageway will quickly reveal any drivetrain vibration, transmission hesitance, or suspension noise that the MOT bay would not necessarily detect.
