What happens
Symptom. Sewing-machine tick from the top of the engine for the first seconds after a cold start.
Cause. Hydraulic lifters drain down overnight, or the VANOS unit's internal bolts loosen.
How to check it
Cold start
Listen at cold start. A tick that fades within 5–10 seconds is normal for this engine and not worth chasing; one that persists once warm is not.
You get one. If the engine is warm when you arrive, come back another day.

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.
