2017 Mercedes-Benz CLA 2.1L Diesel · AD51 ALL

A clear pattern in the MOT history is the steady progression of tyre wear, especially on the front edges and the inner sidewalls of the rear units, with the latest test on 2 July 2026 confirming the tyres are now close to the legal limit and flagging a defective off‑side front wiper blade as a minor defect. Earlier tests also recorded early‑stage wear on both front and rear brake discs, and a low brake‑fluid level in 2023, but none of these items have yet triggered a failure, indicating that the vehicle has remained within acceptable limits while the tyre condition continues to deteriorate. The recorded 87,847 mi over roughly nine years works out to just under 10,000 mi per annum, a usage rate that sits comfortably within the typical band for a mid‑size executive saloon. There are no significant gaps in the MOT chronology, with annual testing from 2022 through 2026, suggesting the mileage figure is reliable and reflects continuous on‑road operation rather than prolonged storage. This level of exposure will naturally accelerate wear on consumables such as tyres, brake pads/discs and wiper blades, while the underlying chassis and power‑train components have not shown any MOT‑recorded concerns. When inspecting the car, pay particular attention to the tyre condition: feel for vibration or pulsation at speeds above 50 mph, listen for thumping noises that may indicate uneven tread wear, and check the sidewalls for bulges or cracks that could precede a failure. The front tyres are flagged as being close to the legal tread limit on both edges, so a replacement set is likely required within the next few thousand miles. Examine the brake discs for scoring or waviness by looking for surface irregularities and listen for a high‑pitched squeal or pedal judder under moderate braking, which would signal that the previously noted wear is advancing toward a serviceable limit. Verify the brake‑fluid reservoir is topped up and the fluid appears clear; a low level noted in 2023 suggests the system may be approaching the recommended service interval. Given the current advisories, budgeting for a full tyre replacement and a brake‑disc inspection or resurfacing is prudent before the next MOT. Replacing the off‑side front wiper blade is a simple, low‑cost fix that will clear the minor defect. Monitoring the brake‑fluid level and topping it up as needed will help avoid a future advisory. With these targeted actions addressed, the vehicle should remain compliant and safe for continued road use.
