2009 Mercedes-Benz Viano 3.0L Diesel · SE05 AND

The 2026‑04‑02 MOT at 144,397 miles passed with no major defects, but recorded near‑side and off‑side rear brake pipe corrosion covered in grease, indicating a continuing mechanical issue. The recurring pipe corrosion, first noted in 2020 and repeated in 2023, 2024 and 2026, shows a worsening trend rather than stability. At 17 years old the van has accumulated 144,397 miles, averaging 8,494 miles per year, which is typical for its age. However, the interval from the 2025‑03‑18 test (138,492 miles) to the 2026‑04‑02 test (144,397 miles) covers only 5,905 miles in 13 months, a rate that exceeds the long‑term average and may reflect increased usage or reduced standing periods. Earlier gaps, such as the 2024‑03‑11 to 2025‑03‑18 period (5,140 miles over 1 year 2 months), also indicate steady but relatively high mileage accumulation. A buyer should therefore prioritize a detailed inspection of the rear brake system, including the corroded pipes, calipers and discs, and verify that the parking brake lever now has adequate reserve travel after the 2017 failure. Attention must also be given to the rear lower gearbox mounting defect recorded in 2023, the suspension bushes and coil springs for wear, and any signs of structural rust around the chassis rails and wheel arches, as these components have been flagged repeatedly. Overall the vehicle is presently roadworthy, but the persistent rear brake pipe corrosion and earlier structural advisories suggest that a thorough in‑person assessment of braking, suspension and chassis integrity is essential before final purchase.
