2018 Mercedes-Benz A-Class 1.6L Petrol · AV18 BCZ

The most recent DVSA test on 23 September 2025 resulted in a pass, but it carried five advisories that warrant careful attention from any prospective buyer. The front suspension arm pins or bushes on both sides were noted as worn without yet producing excessive movement, while a non-excessive oil leak was also recorded. Both front and rear brake pads were flagged as wearing thin, suggesting that pad material is approaching the end of its serviceable life and a replacement should be budgeted in the near term. Looking across the sequence of tests, the overall trend is one of slowly accumulating wear items rather than a clean record. The 2023 advisory for rear inner brake pads was followed in 2024 by front brake disc wear, and the 2025 advisories now combine front and rear brake pad wear with suspension bush wear and an oil leak. While the vehicle has continued to pass each year, the increasing density and variety of advisories indicate that consumable components are reaching a stage where proactive replacement would be prudent. The recorded mileage of 64,584 miles on an eight-year-old vehicle equates to an annual average of around 8,073 miles, which is broadly typical for a car of this age and class. The MOT history does not reveal any unusual gaps in recorded mileage or sudden surges in annual accumulation, suggesting reasonably consistent usage throughout its life. This steady, moderate level of use is mechanically favourable, as it avoids the two extremes that can degrade a vehicle, namely the long periods of standing associated with very low annual mileage, and the accelerated wear on suspension, clutch, and drivetrain components associated with very high mileage. The mileage pattern here implies a vehicle that has been used regularly for ordinary mixed driving, which generally keeps seals lubricated, prevents corrosion from taking hold on brake discs, and allows the engine to reach operating temperature frequently. At this mileage and age, however, the cumulative wear on age-sensitive items such as rubber bushes, coolant hoses, drive belts, and timing chain stretch on the M270 or M282 petrol units commonly fitted to this generation of A-Class should still be considered. Given the recurrence of brake-related advisories across multiple tests, a prospective buyer should pay particular attention to the braking system during a test drive. The 2021 advisories highlighted pitted and scored front discs, the 2024 advisory noted general front disc wear, and the 2025 advisories now flag both front and rear pads as wearing thin, which together suggest the discs and pads may have been left to wear progressively rather than being replaced together. On a test drive, listen for any brake shudder or vibration through the steering wheel under firm braking, which would indicate warped or unevenly worn discs, and watch for the vehicle pulling to one side, which could reveal a binding caliper. Inspect the discs visually for a pronounced lip on the outer edge, an indicator of advanced wear, and check that the brake fluid has been changed recently, as this is a time-based service item rather than mileage-based and is often overlooked. Given that the oil leak advisory in 2025 follows years of clean records, it would be wise to inspect the underside of the engine and the surrounding components for fresh oil residue, particularly around the cam cover, oil filter housing, and turbo oil feed pipes, which are known weak points on Mercedes-Benz M270 engines. The suspension bush wear recorded in 2025 is a significant finding for a vehicle of this age and mileage, as worn front control arm bushes are a common failure point on the Mercedes-Benz A-Class W176 platform. During a test drive, pay close attention to any knocking or clonking noises emanating from the front end when traversing speed bumps, potholes, or uneven road surfaces, as this is the classic symptom of worn bushes allowing excessive play in the suspension arms. Uneven tyre wear, particularly inner-edge feathering on the front tyres, can also indicate that the bushes have degraded to the point of altering wheel geometry. While the current advisories state that movement is not yet excessive, these bushes will progress to a point where they will require replacement, and it is worth obtaining a quote for the work as part of any price negotiation. Beyond the documented items, a buyer should also verify that the cam belt or chain service schedule has been adhered to according to Mercedes-Benz intervals, that the coolant and automatic transmission fluid have been changed at the prescribed calendar intervals, and that the 12V auxiliary battery is in good condition, as Mercedes-Benz vehicles of this era are known for sensitive electrical systems that can behave erratically when battery voltage drops. A pre-purchase inspection by a Mercedes-Benz specialist or independent garage would be strongly recommended to assess the extent of the oil leak and confirm the condition of the suspension components before committing to purchase.
