Historical MOT pass rates and DVLA records for 2005 model year cars.
- Bore Scoring (Gen 1)Serious
The Lokasil/Alusil cylinder liners degrade, causing the piston to score the walls. Eventually requires a full rebuild.
- IMS Bearing (997.1)Serious
While the 997.1 uses a larger bearing than the 996, early 2005 models still use the smaller bearing. Later 997.1 cars use a larger, more robust bearing but failure is still possible.
- Cracked Ignition Coil PacksModerate
The coil packs on 997 engines are prone to cracking and failing, causing misfires. A relatively inexpensive fix but common across all variants.
