Historical MOT pass rates and DVLA records for 2012 model year cars.
- Rear Arch, Sill and Underbody CorrosionSerious
GH cars can rust around the rear arches, sill ends and underbody mounting points long before the cabin or paintwork looks especially shabby.
- Diesel DPF and Oil Dilution TroubleSerious
Short-trip use can overload the DPF regeneration strategy on the 2.0 and especially 2.2 diesels, leading to rising oil levels, warning lights and turbo stress.
- 2.2 MZR-CD Timing Chain Elongation and DPF Warning LightSerious
The 2.2-litre MZR-CD (R2AA) diesel engine is prone to timing chain stretch, accelerated by diesel oil dilution from interrupted DPF regenerations. When chain elongation exceeds 10.45 degrees, the PCM registers fault code P1336 (camshaft/crankshaft sensor range/performance) and commands the DPF light to flash on the instrument cluster. If driven with a loose chain, the chain will rattle against guides, slip teeth or break, causing catastrophic valve-to-piston contact. Rectification requires replacing the timing chain kit, oil pump chain, tensioner and guides, followed by PCM chain elongation calibration.
