2016 DS DS4 1.6L Diesel · WT16 DYB

The vehicle holds a valid MOT certificate issued in May 2025 at 106,761 miles, following a failure on the same day for lighting and brake disc issues that were promptly rectified. The maintenance trend is broadly stable but reveals a persistent pattern of rear brake disc wear. Both the 2024 and 2025 tests flagged the nearside and offside rear outer brake discs as worn, pitted, or scored, indicating the owner has tolerated surface degradation rather than replacing the discs outright. A central rear upper oil leak noted in May 2025 was deemed non-excessive, yet its recurrence warrants closer inspection. The 2024 failure exposed more serious mechanical neglect, with both front lower suspension arm ball joints excessively worn, a split offside front CV boot, and dangerously degraded front tyres. These were rectified before the pass, suggesting reactive rather than preventative maintenance. The mileage progression is consistent and unremarkable for a 2016 vehicle. Between May 2023 at 87,107 miles and May 2024 at 96,970 miles, the car covered 9,863 miles. The following year it added 9,791 miles, arriving at 106,761 miles by May 2025. This equates to roughly 9,800 miles annually, well below the typical UK average of 10,000 to 12,000 miles per year for a petrol or diesel vehicle of this age. The MOT record is complete with no gaps, and the mileage progression is logical with no anomalies suggesting tampering or long periods of disuse. A buyer should prioritise inspecting the rear brake assemblies closely. The repeated advisories on both rear outer brake discs across consecutive years suggest the discs may be below minimum thickness or suffering from uneven wear, potentially indicating binding calipers or a sticking handbrake mechanism. The central rear upper oil leak flagged in 2025 could stem from a failing camshaft cover gasket or a degraded seal on the turbo oil return line if the vehicle is a diesel. Confirm whether the leak has worsened since the test. The 2024 failure for split CV boots and worn ball joints means those components were replaced, but the quality of the aftermarket parts used is unknown. Inspect the front inner wing arches for fresh grease splatter and check the lower arm boots for tears. Jack the front end and check for play in the suspension joints. The high-level stop lamp fault in 2023 was minor, but verify all three brake lamps function correctly, including the LED units common on this model, which can suffer intermittent failures. Tyre condition demands attention. The 2024 failure exposed ply on the offside front tyre and nearside front tread worn to 2mm, suggesting the previous owner ran the car on degraded rubber. Check the date codes and tread depth across all four tyres and the spare. Uneven inner edge wear on the front axle points to tracking or worn suspension bushes, so have the four-wheel alignment verified. Overall, the car appears mechanically sound following its latest pass, but the pattern of advisories and the nature of the 2024 failures indicate a vehicle that has been maintained reactively rather than proactively. A pre-purchase inspection by an independent garage is strongly recommended before committing funds.
