Our Verdict
This Mercedes-Benz C-Class diesel has an
Given that P0546 has appeared on two separate MOT occasions roughly two years apart, this is a recurring rather than transient fault. P0546 is commonly associated with the exhaust gas temperature sensor circuit (Bank 1, Sensor 1), which on the 2.1-litre OM651 diesel can be linked to sensor failure, wiring issues, or DPF-related concerns. P2463 relates to diesel particulate filter restriction, which is a more serious concern on a low-mileage diesel and could indicate short journeys that prevent proper DPF regeneration. Before purchasing, insist on a full diagnostic scan by a Mercedes specialist or independent garage with Mercedes diagnostic capability to read all stored and historic fault codes.
The exceptionally low mileage of 42,368 miles over 17 years averages around 2,500 miles per year, which is well below the typical 8,000-12,000 miles annual mileage for UK vehicles. Low-mileage diesels can actually be problematic if used predominantly for short trips, as this prevents the diesel particulate filter from completing active regeneration cycles. Ask the seller about the vehicle's usage pattern and verify the mileage against any service history, previous MOT certificates, or invoices. Check the service book for gaps, and confirm that the timing belt (due every 4-5 years or 80,000-120,000 miles on the OM651 engine) has been replaced according to schedule.
The 2.1-litre C-Class diesel should return approximately 45-55 mpg in mixed driving, though real-world figures will vary. Road tax (VED) for a 2009 diesel of this engine size typically falls into a moderate band, though diesel vehicles face higher first-year rates and may be subject to charges in Clean Air Zones such as the London ULEZ. Insurance for a Mercedes-Benz C-Class is generally in groups 28-38 depending on exact specification, so premiums will be moderate to high. Annual maintenance costs on a Mercedes of this age can be significant, with specialist labour rates of £80-£120 per hour at franchised dealers, though independent Mercedes specialists offer better value. Given the apparent MOT issues and the need for diagnostic work, budget conservatively.
The two MOT failures both flagged engine MIL illumination with codes P0546 (exhaust gas temperature sensor) and P2463 (DPF restriction). On inspection, ask the garage to check the condition and wiring of the exhaust gas temperature sensors, particularly Bank 1 Sensor 1, as damaged wiring harnesses near the turbo and DPF are common failure points on this engine. Have the DPF measured for soot loading using a diagnostic tool, and check the live data for differential pressure readings. If the DPF is heavily restricted, replacement can cost £800-£1,500 plus VAT at a specialist.
Beyond the MOT-flagged issues, inspect the OM651 diesel engine for oil leaks (the balance shaft gear and front crankshaft seal are known weak points), check the turbo actuator operation, and verify the condition of the timing chain and injectors. On the exterior, examine the front suspension components, particularly the control arm bushes and springs, as these commonly fail on higher-mileage Mercedes of this era. Check for corrosion around the wheel arches, sills, and boot lid, as C-Class models from this period can develop surface rust. Finally, verify that all warning lights clear on start-up and that no lights remain illuminated after the engine has run.
This 2009 Mercedes-Benz C-Class (2.1-litre diesel, registration OV59CPK) has covered just 42,368 miles across approximately 17 years, which is remarkably low for the age. The MOT history shows three tests recorded, with two failures both relating to the engine Malfunction Indicator Lamp (MIL) and associated diagnostic trouble codes P0546 and P2463. The same code P0546 appeared on two separate test dates in 2024 and 2026, suggesting a persistent fault that has not been resolved.
No aggregate MOT reliability data is available for the Mercedes-Benz C-Class in the provided dataset, so an overall model reliability rating cannot be given. The Mercedes C-Class of this generation (W204) is generally regarded as a competent executive saloon, though the OM651 diesel engine has known issues with EGT sensors, DPF clogging on short journeys, and balance shaft wear.
