2009 Mercedes Viano 2.1L Diesel · SD09 VOU

Recurring electronic faults and a pattern of tyre wear define the recent history of this vehicle, which passed its last inspection on 10 February 2026. The record shows a deteriorating trend since a clean pass in 2024, with subsequent tests flagging major failures regarding the electronic stability control warning lamp and the engine management indicator light. The failure on 5 February 2026 was particularly severe, citing dangerous tread depths on both rear tyres, indicating that critical safety components had fallen below the legal limit. With 159,084 miles recorded over 17 years, the vehicle has averaged approximately 9,358 miles annually. This accumulation rate is typical for its age and suggests consistent use rather than prolonged periods of inactivity. Mechanically, this level of mileage implies expected wear on high-stress drivetrain components, suspension bushings, and braking systems, which should be evaluated in the context of the vehicle's role as a heavy-duty multi-purpose vehicle. Particular attention must be paid to the recurring electronic stability control and engine management faults recorded in 2025 and 2026. During a test drive, verify that no warning lamps remain illuminated on the instrument cluster and monitor for any erratic engine performance or hesitation. The presence of a recorded oil leak, though described as not excessive in February 2025, requires a physical inspection of the engine bay and underside for fresh residue or seepage, particularly around the cylinder head and sump gaskets. The repeated advisories and failures concerning tyre wear, specifically the outer edge wear on the front tyres and the dangerous tread depths on the rear, point toward potential alignment or tracking issues. Inspect the current tyre condition for uneven wear patterns and listen for abnormal road noise or feel for any steering pull during the test drive. Ensure that the electronic stability system is functioning correctly, as the previous major failures in this area can impact the vehicle's handling and safety during emergency manoeuvres.
