2021 Ford Focus 1.5L Diesel · CP21 DZF

The 2021 Ford Focus presents a clean and stable roadworthiness profile. The most recent MOT, conducted on 24 September 2025 at 7,919 miles, passed with zero defects recorded. This follows a minor failure the previous day for a non-functioning nearside side repeater, a trivial electrical item that was evidently rectified immediately. The maintenance trend is firmly stable, with no recurring mechanical or structural faults appearing across the entire recorded history. The mileage accumulation is notably low for a five-year-old vehicle. Between the October 2023 test at 4,118 miles and the September 2024 test at 6,286 miles, the car covered 2,168 miles in just under twelve months. The subsequent year saw only 1,633 miles added before the 2025 test. This sub-1,600-mile annual average suggests prolonged periods of static use. Extended standing can cause flat-spotting on tyres, moisture accumulation in the brake system and fuel tank, and deterioration of rubber bushes and seals through lack of lubrication cycling. A buyer should prioritise a thorough inspection of the tyre sidewalls and tread condition, looking for cracking or deformation from stationary loading. The braking system warrants close attention; caliper slides and handbrake mechanisms can seize if the vehicle has sat idle for extended periods. Suspension bushes, particularly the front lower arm and rear trailing arm bushes, should be checked for perishing, as low-mileage vehicles often suffer rubber degradation from age rather than wear. Despite the sparse defect history, a physical underbody inspection remains prudent. Examine the exhaust system for surface corrosion from cold, short-run condensation, and check the subframes and suspension mounting points for early-stage corrosion that MOT tests at this mileage may not yet expose. The clean electrical record is encouraging, but a full diagnostic scan of the body control module is advisable to confirm no latent fault codes exist beyond the simple repeater lamp issue already resolved.
