2013 Vauxhall Mokka 1.7L Diesel · DF63 AAY

An emissions failure recorded in the 2024 MOT dominates the recent mechanical narrative of this 2013 Vauxhall Mokka; the test flagged exhaust emissions well beyond the 1.5 g km‑¹ limit and identified dangerous smoke that could obscure other road users, while the same inspection also noted a discoloured nearside side repeater. The following year’s MOT (December 2025) showed a clean pass with no defects, indicating that the emissions issue was either remedied or not re‑tested, but the repeat advisory on the side repeater persists, suggesting a lingering electrical or bulb‑related concern. With just 49,294 mi recorded over roughly thirteen years, the vehicle averages about 3,800 mi per annum – considerably below the typical UK usage pattern for a family SUV. Such low annual mileage can imply periods of limited operation, which may exacerbate fuel‑system deposits and affect catalytic converter efficiency, potentially linking to the earlier emissions failure. There are no significant gaps in the MOT chronology; tests have been conducted annually, providing a consistent snapshot of the car’s condition despite the modest mileage. Prospective buyers should give particular attention to the exhaust and emissions system. Verify that the catalytic converter shows no rattling, excessive heat, or visible damage, and confirm that the engine runs cleanly without black or blue smoke at idle and under load. Inspect the nearside side repeater lamp for proper illumination and replace the bulb or address wiring corrosion if the light continues to flash white. The 2023 advisory about rear brake pads being thin also warrants a thorough brake inspection; measure pad thickness, check for uneven wear, and ensure the discs are free from scoring or glazing. During a test drive, listen for any unusual exhaust notes such as hissing, popping, or a pronounced smoky plume, especially during acceleration and deceleration. Feel the rear brake pedal for a soft or spongy feel, which could indicate worn pads or air in the hydraulic line, and note any pull or vibration when braking. Observe the dashboard for the side repeater warning and confirm that it illuminates correctly. A post‑test‑drive visual inspection of the exhaust manifold, tailpipe, and brake components will help confirm whether the previously flagged issues have been resolved or require further remedial work.
