✓ The faults of this engine were checked against sources (10/2026). Each item has at least two independent sources or an official recall or parts-maker technical note.
Ignition coil pack or HT leads fail (misfire)
usually 60,000–180,000 km · Wear part
Signs: Misfire, rough idle, flashing engine light, P030x codes, sometimes visible sparking at the leads in the dark or wet
Fix: Check plugs, leads and the coil pack; replace the leads as a set with good-quality parts and the coil pack if it is cracked or weak
€50–200
Unstable idle or stalling: dirty throttle body, idle valve or MAP sensor
usually 60,000–200,000 km · Wear part
Signs: Hunting or pulsing idle, stalling when coming to a stop, sometimes worse in damp weather; throttle position fault codes on electronic throttles
Fix: Clean the throttle body, the idle control valve (cable-throttle 1.1 and early 1.2) and the MAP sensor, check the breather hoses, then run the throttle adaptation; replace the throttle body if the position sensor is faulty
€50–350
Crankshaft position sensor failure (cuts out, no start, P0335)
usually 60,000–200,000 km · Medium risk
Signs: Engine cuts out while driving or will not start, often when hot, then restarts after cooling; code P0335
Fix: Read the fault memory, check the sensor plug and wiring, and replace the sensor with a quality part
€50–150
Thermostat leaks past its seal (slow warm-up, P0115 / P0128)
usually 60,000–180,000 km · Wear part
Signs: Temperature gauge stays low, weak heater, fans start early, engine light with coolant temperature codes
Fix: Replace the thermostat (check which of the two types the engine has), refill and bleed the cooling system, and renew old coolant
€60–200
Water pump leaks before the timing belt is due
usually 80,000–160,000 km · Medium risk
Signs: Coolant loss, coolant traces or crust at the pump behind the timing cover, noise from the pump bearing
Fix: Replace the pump together with the timing belt kit; use only a thin bead of sealant on the pump
€200–450
Head gasket failure after overheating
usually 100,000–220,000 km · Medium risk
Signs: Coolant loss without a visible leak, white smoke, mayonnaise under the oil cap, overheating, bubbles in the expansion tank
Fix: Pressure and CO test of the cooling system; replace the head gasket, have the head checked for flatness, and fix the cause (thermostat, pump, fan, leaks)
€400–900
Oil seepage: cam cover gasket and crankshaft seals
usually 80,000–250,000 km · Wear part
Signs: Oily engine, oil drops under the car, oil smell; oil can reach the coil pack area on top of the engine
Fix: Find the leak and replace the cam cover gasket or the leaking crankshaft seal; a rear crankshaft seal needs the gearbox removed
€50–450
