2011 Mercedes Motorhome 3.0L Diesel · WR11 ALY

The most recent MOT test on April 17, 2025, confirms this 2011 Mercedes motorhome remains roadworthy with no defects recorded at 34,827 miles. The overall trend since 2021 shows consistent pass statuses, though the 2024 cycle includes an unusual double entry—one pass and one fail at nearly identical mileages (31,853 and 31,843)—which suggests either a test date overlap or a brief period of non-use between tests. No recurring advisories or major failures appear in the record, indicating the vehicle has avoided critical mechanical issues during its low-mileage service life. The recorded mileage of 34,827 miles over 15 years equates to approximately 2,322 miles annually, which is unusually low for a vehicle of this age and type. The largest gap between tests spans from September 2021 (24,463 miles) to February 2023 (29,492 miles), a 15-month period covering 5,029 miles—suggesting prolonged storage or minimal use. The subsequent tests in 2024 and 2025 show no significant mileage jumps, reinforcing the pattern of light usage. While low mileage generally reduces wear on high-stress components, it also raises questions about fluid maintenance (e.g., brake fluid, coolant, transmission fluid) and potential long-term degradation from static conditions. Given the lack of recorded defects, the primary focus for an in-person inspection should centre on components prone to prolonged neglect in low-mileage vehicles. Verify the condition of suspension bushes and coil springs for perishing or cracking, particularly around the rear axle where binding brakes were not explicitly ruled out in past tests. Examine the brake system for corrosion on calipers, binding rotors, or uneven wear, as the 2024 double-test anomaly could hint at intermittent brake issues. Structural integrity should be checked for corrosion in wheel arches, subframe areas, and underbody panels, especially if the vehicle was stored in damp conditions. Finally, inspect the exhaust system for leaks or rusted joints, as emissions-related failures are common in older motorhomes and may not always appear in MOT records.
