Ti-VCT cam phaser rattle or sticking (1.6 Ti-VCT)
usually 80,000–180,000 km · Medium risk
engine codes: HXDA, HXDB, HXJA, IQJA, IQDB, PNDA
Signs: Rattle for a few seconds after a cold start, rough idle, engine light with cam timing codes (P0011, P0016, P0017), sometimes limp mode
Fix: Check oil level and grade, then the VCT solenoids; replace the phaser(s) together with the timing belt kit if they are worn
€150–900
Ignition coil and plug failures, often from water in the plug wells
usually 60,000–180,000 km · Wear part
Signs: Misfire, shaking at idle, flashing engine light, often after rain or a car wash
Fix: Dry the plug wells and clear the scuttle drains, replace the coil pack and plugs, use dielectric grease on the connectors
€100–250
Electric fuel pump failure
usually 80,000–200,000 km · Medium risk
Signs: Long cranking, stalling or hesitation under load, sometimes no start
Fix: Measure fuel pressure and pump current; replace the in-tank pump module

Oil leaks at the valve cover and crankshaft seals
usually 80,000–200,000 km · Wear part
Signs: Oil sweating on the head or between engine and gearbox, oil drops under the car
Fix: Replace the valve cover gasket; renew the front crank seal with the timing belt and the rear seal with the clutch

Valve clearance drift (shim tappets, no hydraulic lifters)
usually 100,000–250,000 km · Wear part
Signs: Ticking from the head, rough idle; on LPG, burnt exhaust valves if clearances close up
Fix: Check clearances about every 100,000 km (more often on LPG), ideally with the timing belt change, and correct with shims
