2016 Ford Fiesta 1.0L Petrol · SD16 PUU

The 2016 Ford Fiesta presents a generally stable mechanical picture as of its most recent MOT on 13 March 2026 at 55,424 miles, where it passed after an earlier failure on the same day. That initial failure flagged a Lambda reading outside specified limits during the second fast idle, a loose central heat shield, and a blowing front flexi exhaust, all of which were rectified before the afternoon retest. The Lambda fault points to a momentary emissions control irregularity rather than a chronic engine issue, and the heat shield and exhaust repairs suggest the previous owner addressed the failures promptly rather than ignoring them. The maintenance trend is therefore stable, with no evidence of worsening mechanical decline. The mileage accumulation tells a story of genuinely light use. Between the April 2024 pass at 41,291 miles and the March 2025 test at 48,605 miles, the car covered 7,314 miles in roughly eleven months. Then from March 2025 to March 2026, it added only 6,819 miles. Over its ten-year life, the annual average sits at approximately 5,542 miles, well below the typical UK annual figure of 8,000 to 12,000 miles. This low usage pattern means reduced wear on drivetrain and suspension components in absolute terms, though it also raises the possibility of long stationary periods, which can cause its own issues such as deteriorated rubber bushes, flat-spotted tyres, and moisture ingress into brake and fuel systems. Buyers should pay close attention to the front exhaust flexi section, which has appeared in three consecutive MOT records. It was noted as slightly blowing in April 2024, recorded as a minor leak in the March 2025 failure, and flagged as blowing again in the March 2026 failure before the same-day pass. This recurring advisory pattern indicates the flexi joint is a known weak point on this example, and a replacement may be due soon even though it currently passes. The Lambda reading failure in March 2026, while resolved, warrants a check of the catalytic converter and oxygen sensors to confirm they are functioning within tolerance under varied load conditions. The side skirts fitted at the March 2026 test are worth inspecting underneath for trapped moisture or corrosion, particularly if they are aftermarket additions covering original sill edges. With only four MOT records spanning roughly two years, the service history is sparse, so a thorough underbody inspection for structural rust, brake condition, and suspension bush wear is advisable before purchase.
