Symptom. Metallic rattle, fuel-pressure faults, rough running; in the worst case metal debris through the engine.

Cause. The follower between the camshaft and the high-pressure fuel pump wears through. It's a cheap part that causes expensive damage if left.

The last column is the point. The same repair is an inconvenience on one variant and a reason to scrap the car on another. A failure costing a quarter of the vehicle's value changes the purchase decision regardless of how rare it is.
