2018 Ford Transit Courier 1.5L Diesel · FX68 KFN

The vehicle is currently unroadworthy following two consecutive failures in April 2026. While the van maintained a clean record for several years, the maintenance trend has shifted from stable to a critical mechanical failure. The failures on April 7 and 8, 2026, at approximately 31,800 miles for exhaust emissions exceeding manufacturer limits indicate a significant engine management or fuel delivery issue that was not present during the previous annual tests. The mileage profile is notably low for an eight-year-old commercial, averaging roughly 4,000 miles per year. There is a significant gap in usage data between February 2023 at 20,984 miles and March 2024 at 30,316 miles, where the vehicle covered nearly 10,000 miles in a year. This irregular usage pattern suggests long periods of standing, which often leads to the degradation of rubber components, fuel contamination, or carbon buildup, explaining the recent emission failures despite the low odometer reading. A buyer must prioritize a diagnostic inspection of the exhaust system to determine if the failure is caused by a faulty oxygen sensor, failing injectors, or a restricted diesel particulate filter. The 2024 advisory regarding play in the nearside front track rod end ball joint indicates that suspension components are beginning to age regardless of mileage, necessitating a thorough check of all front end bushes and steering linkages. Given the low mileage, the inspector should also check for brake corrosion and seized calipers, as these are common issues on vehicles that remain stationary for extended periods.
