2013 Mercedes-Benz CLS 2.1L Diesel · CE03 KLE

The defining mechanical story of this CLS is a recurrence of braking and suspension wear alongside a notable tyre integrity issue that surfaced in the most recent test. Across seven recorded tests since 2021, two failures have been logged, both within days of a subsequent pass, indicating that remedial work is being carried out between attempts. The 2025-09-08 failure included dangerous tyre defects on both the offside front (ply or cords exposed) and the nearside rear (structural bulge from separation), which are not minor advisories but categorised as dangerous defects at the time of test. The same visit also produced a major registration plate non-conformity. The re-test eight days later on 2025-09-17 returned a pass but retained the oil leak advisory alongside four tyre-related advisories concentrated on the nearside front, covering a cut, perishing or cracking, edge wear, and a worn condition approaching the legal limit, plus a general brake disc advisory noting pitting and scoring on both front and rear axles. Going further into the record, the 2022 and 2023 entries show a pattern of front coil spring failure, front inner brake disc wear that was deemed significantly and obviously worn at the 2022-08-05 failure, persistent front wheel bearing play recorded on multiple occasions, and recurring rear brake disc and pad advisories. The 2024 test passed with only an under-tray advisory restricting visibility, which interrupts but does not reset the broader pattern of component wear that has resurfaced in the latest test. Recorded mileage stands at 114,010 miles against an age of approximately thirteen years, yielding an average accumulation of roughly 8,770 miles per year, which is broadly typical for a vehicle of this age. There is no evidence of long periods off the road, nor of rapid mileage escalation between tests; annual usage appears steady and the gaps between tests generally align with MOT frequency rather than extended lay-ups. This consistency means wear-related findings on consumables such as brake discs, pads, coil springs and tyres are likely to reflect genuine component service life rather than the consequences of standing idle or unusually heavy use. The recurrence of advisories on the same components across multiple years suggests these parts are approaching or at the end of their functional interval at roughly this mileage band, which is consistent with what would be expected from a CLS of this age. For a prospective purchase, the brake system warrants the closest physical inspection. The 2025 advisories note pitted and scored brake discs on both front and rear axles, and earlier records show significantly worn front inner discs in 2022, so a thorough check of disc thickness, lipping on the outer edge and pad material remaining is essential. On a test drive, listen for any brake squeal or grinding under light application, and feel for judder through the pedal or steering wheel under firm braking, which would indicate disc runout beyond serviceable limits. Inspect the nearside front tyre closely for cracking across the sidewall and tread blocks, as the advisories record perishing alongside edge wear, and confirm there is no exposed ply or cord anywhere on the tyre. The 2025-08 oil leak advisory, recorded as not excessive, should be checked by inspecting the underside for fresh oil residue around the engine and turbo area common to this model, and noting whether any drips are present on the driveway after standing. Suspension and steering components also need direct attention given the recorded history. A fractured offside front coil spring was identified in August 2023 and a replacement should be verified, but the opposite side and the rear springs should also be examined for any sagging or broken coils, which on test would present as a clonking noise over speed humps or uneven ride height at the front. Front wheel bearing play has been noted repeatedly since 2022, so with the wheels off the ground, any roughness, notchiness or looseness when the front wheels are rotated by hand should be taken seriously, as should any humming that varies with road speed during the drive. The registration plate issue from the September 2025 failure should be confirmed as rectified, and a final check that all four tyres are of matching size and have adequate tread depth across the full width will address the recurring tyre-related advisories seen throughout the record.
