2019 Mercedes-Benz GLC 300 AMG Line Prem D 4M A 1.9L Diesel · FD69 EZP

The most recent DVSA MOT test for this 2019 Mercedes-Benz GLC 300 was conducted on 11 May 2026, resulting in a pass with no defects or advisories recorded. This represents a clear improvement over the immediately preceding test in March 2025, which failed with two dangerous tyre depth defects, a malfunctioning tyre pressure monitoring system, and an ineffective front wiper. The fact that the dangerous tyre non-compliance was addressed and the wiper and TPMS faults were remedied before the subsequent pass suggests the owner acted decisively on the safety items, and the broader maintenance trend can be considered stable to improving at the point of the most recent test. Earlier tests in March 2024 and January 2023 were passed without any advisories, further reinforcing the impression of a generally well-maintained vehicle, although the 2025 cluster of defects is worth examining more closely as part of any pre-purchase evaluation. With 53,261 miles recorded over approximately seven years, the GLC has covered an average of around 7,600 miles annually, which is broadly typical for a premium SUV of this age and aligns closely with average UK driving patterns. There is no evidence in the MOT history of an unusually low or garage-queen mileage profile, nor of rapid accumulation that would suggest motorway-fleet abuse, so the wear rates on major mechanical components such as the engine, transmission, four-wheel-drive system and braking hardware are likely to be proportionate to the mileage shown. Buyers should nevertheless satisfy themselves that the recorded figure is continuous, as DVSA records only capture mileage at test time, and any unexplained gaps in the service book or V5C should be queried with the seller. A 2.1-litre diesel of this vintage with this mileage is approaching the point where several major service items, including timing chain inspection if applicable on this OM654 unit, diesel particulate filter condition, and AdBlue system checks, become prudent considerations. The 2025 advisories for nearside front and rear tyres worn on the edge are a useful pointer when inspecting the vehicle, as edge wear is typically symptomatic of wheel alignment irregularities, worn suspension components, or under-inflation rather than simple tread consumption. On a test drive, listen for any clonking or knocking from the front suspension over speed humps and uneven surfaces, which could indicate worn control arm bushes, top mounts, or anti-roll bar links common to this model. Steering should feel precise and self-centring, with no vibration through the wheel at speed, and the vehicle should track straight without pulling. Inspect the tyres themselves for even shoulder wear, and check that all four tyres are of matching make, size,255/45/20 as noted on the failure record, and speed rating, as mixed fitments can affect the all-wheel-drive system. The earlier dangerous failures for sub-1.6mm tread and TPMS issues should be fully resolved, and any reoccurrence would suggest the vehicle is not being maintained to a satisfactory standard. Given the vehicle's age and moderate mileage, several time-based rather than mileage-based checks are worthwhile before purchase. Brake discs on a seven-year-old car that has spent time standing or has been used for predominantly short journeys may exhibit corrosion or lipping on the outer edges, and calipers can seize partially, leading to uneven pad wear or a dragging sensation on test drive. The 12V battery, particularly if the original AGM unit, may be approaching the end of its service life, and any warning messages on the dashboard regarding battery or auxiliary systems should be noted. Brake fluid hygroscopically absorbs moisture and should have been changed at least every two years regardless of mileage, so verify the date of the last fluid service. Likewise, coolant, transmission fluid and the diesel fuel system, including the AdBlue injector and DPF, are time-sensitive items on a vehicle of this age. Inspect undertrays and underbody panels for any signs of oil or coolant leaks, examine the exhaust system for corrosion particularly around mounting points and the DPF, and finally confirm that the digital service record on the Mercedes-Benz system matches the paper history, as a verified service chain is essential for retained warranty coverage and future residual value.
