2018 Mercedes-Benz C 2.1L Diesel · KT18 MKV

The 2026‑02‑05 MOT records a failure for an inoperative engine malfunction indicator light (8.2.1.2 (h)), meaning the vehicle is presently not roadworthy despite a pass recorded on the same day at 98,993 miles. Repeated engine MIL faults in 2025 and 2026, together with persistent tyre wear, reveal a deteriorating maintenance trend rather than stability. Mileage has risen from 33,801 miles in June 2021 to 98,993 miles by February 2026, averaging about 12,374 miles per year, which is high for a vehicle of this age. The annual test interval shows steady accumulation, with a notable jump of 24,541 miles between the 2025 and 2026 tests, suggesting intensified use or extended intervals between servicing. A buyer should prioritize inspection of the engine management system, as the MIL fault recurs, and examine the rear braking assembly for binding calipers, worn pads and distorted discs, both indicated in the 2025 and 2026 records. The off‑side rear tyre, consistently worn close to the legal limit, warrants close measurement, while the suspension bushes and coil springs, flagged for wear in earlier tests, should be checked for play or cracking. Finally, the history shows no structural rust advisories but the high mileage and repeated tyre and brake issues imply accelerated wear on chassis components and exhaust systems; a thorough visual inspection for corrosion, exhaust leaks and structural integrity is essential before purchase.
