2016 MG 6 1.8L Diesel · MW16 AKU

A chronic pattern of front-end wear advisories combined with a significant electrical and lighting failure cluster defines the mechanical story of this 2016 MG 6, which otherwise maintains a broadly passable roadworthiness profile. The most recent test on 20 May 2026 returned a clean pass with no defects recorded, suggesting the immediate safety-critical systems are currently sound, yet the history reveals a vehicle that has not been entirely trouble-free. In the 2024 test cycle, the car suffered a major failure related to the headlamp levelling device being corroded and broken, alongside two further major defects involving incorrect beam image projection and an offside headlamp aimed too low. These were all rectified to achieve a pass two days later, but the failure illustrates genuine vulnerability in the front lighting and self-levelling hardware, areas known to suffer on vehicles that have endured damp conditions or minor front-end impacts. Combined with repeated advisories for suspension and brake components, the record points to a chassis that is beginning to show its age despite the modest annual use. With only 27,118 miles accumulated over a full decade, this MG 6 averages roughly 2,712 miles per year, which is exceptionally low for a vehicle of this vintage and significantly below typical commuter-car usage. Such limited mileage raises the likelihood that the car has spent extended periods stationary, potentially exposing rubber and polymer components to premature deterioration through lack of regular flexing and lubrication circulation. The MOT history supports a consistent low-use pattern, with tests recorded annually from 2023 through 2026 without any unexpected mileage surges or gaps that might suggest the odometer has been paused or the vehicle taken off the road for prolonged repairs. Mechanically, this profile implies that while major drivetrain components such as the engine, transmission, and clutch are unlikely to be heavily worn, ancillary items like brake calipers, suspension bushes, drive shafts, and underbody fasteners may exhibit surface corrosion or seizing due to infrequent use rather than active wear. A prospective buyer should pay particular attention to the front anti-roll bar linkage and ball joint components, as the 2025 advisory noted slight play in the offside front ball joint. During a test drive, listen for clonking noises over uneven surfaces and pay attention to any vagueness or knocking through the steering when traversing speed bumps or potholes. The front brake pads were flagged as wearing thin in 2023, and while the 2024 test noted that all brake pipes had been greased rather than replaced, it is prudent to inspect the calipers for any binding or uneven pad wear, test the pedal for firmness, and verify there is no pulling to one side under braking. Underneath the vehicle, examine the brake and fuel lines carefully for any advanced corrosion, particularly around jacking points and suspension mounting areas, as the greasing noted may have been a temporary preservative measure rather than a permanent fix. The lighting and headlamp levelling defects from the 2024 failure warrant close inspection as well. Both headlamp units should be checked for condensation inside the lenses, secure alignment, and full functionality of the automatic levelling mechanism, especially given that the rear levelling device was found corroded and broken. Any warning lights on the dashboard relating to lighting or suspension height should be investigated before purchase. On the test drive, monitor for any flickering or uneven beam pattern at night and confirm that the headlamps self-level correctly when the vehicle is loaded or unloaded. Finally, given the low annual mileage, particular attention should be paid to the condition of all tyres, as they may be older than their tread depth suggests, and a thorough check for any oil leaks from the engine and transmission is advisable, as seals can harden and weep during prolonged periods of infrequent use.
