Question 1

Ignition coil failure causing misfires

Accepted Answer

Intermittent misfires, rough idle and occasional loss of power appear from around 90,000 km as the coil windings over‑heat and crack, potentially damaging the catalytic converter if left unchecked.

Question 2

Timing belt and tensioner wear

Accepted Answer

A ticking noise and occasional loss of timing appear after 80,000‑100,000 km when the belt or tensioner loses elasticity, risking catastrophic engine damage if the belt snaps.

Question 3

Rear wheel‑arch rust and corrosion

Accepted Answer

Visible rust spots develop on the inner rear arches after about 120,000 km, especially in salty climates, leading to paint peeling and eventual metal thinning if not treated.

Question 4

Power‑steering fluid leak from pump seals

Accepted Answer

A gradual loss of steering assist and a low fluid level warning appear after roughly 90,000 km as the pump seals deteriorate, making steering heavy and potentially damaging the pump.

Question 5

Clutch slave‑cylinder leak causing hard shifts

Accepted Answer

Gradual difficulty in shifting into gear and a spongy clutch pedal develop after about 80,000 km as the slave‑cylinder seals leak hydraulic fluid, reducing clutch actuation force.
