1998 Mercedes-Benz Sprinter 2.9L Diesel · R808 COT

The most recent DVSA MOT on 23 April 2012 recorded a pass, but it was accompanied by several advisories – notably slight free play in the steering column, mild corrosion on the nearside front brake pipe and a number of non‑functioning side‑marker lamps. Earlier tests in the same year and the preceding years were marked by multiple failures, especially concerning headlamp aim, brake hose deterioration and a seized brake load‑sensing valve. Although the vehicle has managed to achieve passes since 2010, the persistence of advisory items indicates a maintenance pattern that has improved from outright failures to manageable defects, yet it remains far from a fully resolved condition. With 351,524 mi recorded on a 1998 Sprinter, the average annual mileage works out at roughly 12,500 mi, which is well above the typical 8,000‑10,000 mi for a light commercial vehicle of this age. The high utilisation suggests accelerated wear on consumables such as tyre tread, brake linings, suspension bushings and engine oil. There are no obvious gaps in the mileage record, implying the vehicle has been in regular use rather than long periods of storage; consequently, components that are sensitive to cumulative distance – for example the front and rear brake hoses, steering rack bushings and wheel bearings – are likely approaching the end of their service life. A prospective buyer should give particular attention to the steering system, checking for any looseness or clunking when turning the wheel at low speed and confirming that the steering column does not exhibit excessive free play. The brake system warrants a thorough inspection: the nearside front pipe corrosion should be examined for rust penetration, and both front brake hoses – previously flagged as excessively deteriorated – must be probed for cracks, swelling or fluid leakage. Verify that the brake load‑sensing valve now moves freely, as a seized valve can cause uneven braking and a hard pedal feel. The headlamp aim and operation should be re‑checked, since repeated failures for high aim and non‑functioning lamps were recorded; mis‑aimed beams can lead to glare and reduced night visibility. While the MOT noted thin front pads, the condition of the discs, calipers and any signs of uneven wear or shudder when braking should be assessed during a test drive. Also inspect the suspension ball joints on both front axles for any play or knocking, and examine the anti‑roll bar bushings for hardening or cracking, as these can affect handling stability. Given the vehicle’s age of 28 years, time‑related degradation must be addressed regardless of mileage. Examine all tyres for sidewall cracking, dry rot or loss of tread depth, as rubber perishes even on low‑use tyres. Check the 12 V battery for sulphation and verify that it holds charge, especially if the vehicle has been idle for periods. Look for signs of corrosion on chassis mounting points, exhaust hangers and under‑body panels, which can lead to structural weakening. Finally, confirm that all fluid reservoirs – engine oil, coolant, brake fluid and gearbox oil – have been refreshed within the recommended service intervals, and that the service book contains recent stamps; old or contaminated fluids can cause premature wear in the engine, transmission and braking circuits.
