2017 Scania R500 12.7L Diesel · TKZ 212

The vehicle passed its most recent MOT on 11 December 2025 at a recorded 495,796 miles, with the tester logging no defects or advisories. That makes three consecutive passes in a row, so on paper the maintenance trend looks stable and the roadworthiness status appears sound. But the test history loses credibility the moment you compare the recorded mileages across the three entries. The mileage pattern is not plausible. On 17 January 2024 the odometer read 748,359 miles. On 10 January 2025 it read 775,707 miles, meaning roughly 27,300 miles had been covered in a year. Then on 11 December 2025 the recorded figure dropped to 495,796 miles, a decrease of 279,911 miles in eleven months. That is impossible through normal driving. Either the odometer has been tampered with, the instrument cluster was replaced and the replacement was not calibrated to show the true total, or one of the readings is a clerical error. Given the two earlier entries, the vehicle has most likely covered a genuine total in the region of 780,000 to 800,000 miles. The 495,796 figure cannot be accepted as the true accumulated mileage. Because none of the MOT entries carry any advisories, there is no documented history of suspension, brake, or structural faults to track. That clean record does not reassure me at this mileage; it simply means the likely wear areas were never flagged. At anything over 750,000 miles, a heavy vehicle of this type will typically need attention to front suspension bushes, brake discs and pads, air suspension bellows, and kingpin wear, with corrosion to chassis members and crossmembers also a genuine possibility. The buyer should commission an independent inspection covering those areas, plus a decelerometer or rolling-road brake test, and verify the digital tachograph and the recorded mileage against workshop servicing invoices dating back to 2024.
