EGR Valve/Inlet Manifold Cracking on High-Mileage Diesels (see FAIL-000075); Windscreen Water Leaks; Sagging Tailgate Hinges; Electric Handbrake Faults; Tow Assist System Faults

Emissions (diesel, high-mileage); Body/Water Sealing; Body/Mechanical; Electrical/Braking; Driver Assist · severity: Moderate to High for the high-mileage diesel EGR/inlet manifold finding (see FAIL-000075 - a described unusually invasive repair). Moderate for the electric handbrake fault (a real safety-relevant concern if it sticks on) and water leaks (real risk of interior damage/mould if persistent). Low to Moderate for the tailgate hinge and Tow Assist findings - real but more typical wear/convenience-feature territory. · confidence: 45/100 · 2 cited sources

Symptoms to watch for

  • High-mileage diesel: see FAIL-000075 for the EGR/inlet manifold cracking finding
  • Water leaks from the windscreen area, soaking the headlining and carpets - a real, described issue worth checking for on inspection
  • Sagging tailgate hinges making the tailgate hard to close
  • Electric handbrake malfunctioning - described as potentially sticking on, a real functional/safety concern if it occurs
  • Tow Assist system not working at all in some reported cases - relevant given this vehicle's real-world towing use case
The specific fault codes and inspection steps to check before you buy, a full repair-cost estimate, TSB/recall reference, and the buyer negotiation tip for this issue are included in the R99 vehicle report.
