2009 Mercedes C 2.1L Diesel · KP09 YHX

The vehicle presents a mixed maintenance picture following its most recent MOT pass on 17 February 2024 at 158,870 miles. That test cleared the car, but only after a failure the previous day on 16 February 2024 at the identical mileage. The tester flagged an excessively worn offside front lower suspension arm ball joint, excessive play in the nearside front wheel bearing, and worn rear brake discs. All three defects were rectified before the pass test 24 hours later, suggesting reactive rather than preventative maintenance. The trend is therefore one of short-term fixes rather than sustained proactive upkeep. Mileage accumulation tells a clearer story. Between 14 July 2020 at 127,790 miles and 22 February 2023 at 133,080 miles, the car covered just 5,290 miles in over two and a half years. That is unusually low and raises the possibility of long periods standing, which can cause tyre flat-spotting, brake surface corrosion, and dried-out rubber bushes. From February 2023 to February 2024, the car then added 25,790 miles in a single year, a sharp increase that points to heavier recent use. The current recorded mileage of 158,870 miles is broadly typical for a 2009 vehicle at roughly 9,300 miles per year, but the uneven spread across the record is worth noting. Buyers should focus their inspection on the front suspension and wheel bearings, which have appeared repeatedly. The 2024 failure for a worn lower ball joint and the 2023 advisory for slight play in both front wheel bearings suggest these components have been under sustained stress. Have a garage check the nearside and offside front suspension arms, track rod ends, and wheel bearings for play or deterioration. The rear brake discs have drawn advisories in both 2023 and 2024, so inspect them for thickness, scoring, and heat cracking, along with the rear calipers for signs of binding. The 2021 failure for a fractured offside rear coil spring is a more serious historical concern. Although it was repaired, examine the rear suspension mounting points and spring seats for corrosion or damage. The repeated minor lighting faults on the rear registration plate are trivial but indicate a pattern of small electrical items being left unresolved. Overall, the car appears mechanically functional today, but the record suggests a history of addressing failures as they arise rather than systematic preventative care.
