Historical MOT pass rates and DVLA records for 2012 model year cars.
- Coolant Leak in Engine "V"Moderate
The coolant shut-off valve fails, filling the engine "V" between the cylinder banks with coolant, causing a gradual loss that can lead to overheating if not topped up.
- 3.0 TDI Timing Chain RattleSerious
The V6 TDI timing chains sit at the rear of the engine and the hydraulic tensioners can weaken, causing cold-start rattle and potential chain jump if ignored.
- DPF Clogging and Regeneration IssuesModerate
Town-driven 3.0 TDI models block their DPFs, causing warning lights, limp mode and expensive DPF cleaning or replacement.
