2011 Mercedes-Benz CLS 3.0L Diesel · FR61 OUB

The 2011 Mercedes-Benz CLS holds a current MOT valid until May 2026, having passed its most recent test on 20 May 2025 at 134,488 miles. The maintenance trend is stable but reveals a pattern of deferred minor defects rather than proactive servicing. In the September 2025 test, the tester flagged slight play on both front lower suspension arm ball joints, a known wear point on this platform that typically manifests beyond 100,000 miles. These advisories were present on the failed test three days prior and remained on the pass certificate, suggesting the deterioration is borderline and being monitored rather than rectified. The vehicle has not suffered any major structural or mechanical failures, but the record shows a reliance on borderline component condition rather than preventive replacement. The mileage progression indicates consistent, typical use for a fifteen-year-old saloon. From the failed test on 17 May 2025 at 134,444 miles to the pass on 20 May 2025 at 134,488 miles, the vehicle covered 44 miles in three days, which is negligible and consistent with a retest run. Between the 2024 test at 118,012 miles and the 2025 test at 134,488 miles, the car covered 16,476 miles in approximately twelve months, a slightly elevated annual figure compared to the 8,966-mile lifetime average. This suggests recent heavier use, possibly motorway commuting, which places additional stress on consumable components like tyres and suspension bushes. The 2024 failure for a missing nearside rear wheel fixing is a notable anomaly that warrants attention, as it points to a wheel removal and refit that was not completed to specification. A buyer should focus the physical inspection on the front suspension and wheel components. The recurring advisories for slight play in both front lower suspension arm ball joints indicate the front end is approaching a serviceable limit. Check for uneven tyre wear, particularly inner edge wear on the front axle, which would confirm alignment issues or worn bushes. Inspect the rear wheel fixings thoroughly given the 2024 failure for a missing component, ensuring all nuts and mating surfaces are intact and free of corrosion. The 2024 failure also noted an inoperative nearside rear headlamp levelling device linked to a suspension arm, so verify the self-levelling function operates correctly and the ride height is even. Examine the bonnet primary retaining device, flagged as slightly deteriorated in both 2024 tests, to confirm the secondary latch is secure. While no corrosion or structural defects appear in the record, a thorough underside inspection for rust on subframes and suspension mounting points remains prudent at this mileage.
