2015 Fiat Doblo 1.6L Diesel · MK15 GTU

The vehicle remains roadworthy, but the maintenance history shows a clear trend of developing structural and mechanical wear. While the most recent test in December 2025 at 84,391 miles passed, it introduced a new minor exhaust leak and noted persistent corrosion on the nearside rear suspension mounting. This specific corrosion has appeared in three consecutive annual tests, indicating that while it is currently below the failure threshold, it is progressing rather than being addressed. The mileage pattern is remarkably consistent, averaging approximately 7,700 miles per year over the five years of recorded history. Between December 2022 and December 2023, the vehicle covered only 1,909 miles, suggesting very low annual usage or long periods of inactivity. This low mileage often explains less wear on drivetrain and engine components, but it can also correlate with accelerated corrosion on metal surfaces and brake components, as seen with the pitted and scored nearside front brake disc noted during the 2023 test. A buyer must prioritise a physical inspection of the nearside rear suspension mounting area to determine if the corrosion has compromised the structural integrity of the outer sill. The 2023 advisory specifically mentioned corrosion on the outer sill, which requires close scrutiny to ensure it does not transition into a structural perforation. Additionally, the minor exhaust leak identified in the 2025 test should be checked for a blown gasket or manifold crack, as these issues will likely lead to a failure if the leak worsens before the next inspection.
