Replacement Interval
Preventive replacement every 90 000 km or when cold-start problems appear.
Glow plugs are a wear item that many drivers change only when they fail. Preventive replacement is cheaper and more reliable than emergency replacement in winter.
Symptoms of Faulty Glow Plugs
- Hard cold starts, especially below –5°C
- White smoke from the exhaust during warm-up
- Pre-heat indicator stays on too long or flashes
- Rough running immediately after start
- Fault codes P0671–P0678 (glow plug circuit malfunction, cylinder N)
Replacement Tips
- Replace as a full set — all cylinders at once, otherwise the problem will return within months.
- Torque — for M8x1 thread: 10–15 Nm. Over-tightening causes the plug to snap.
- Anti-seize — apply copper grease to the thread before installation (keep the electrical contact free).
- Cold engine only — always remove glow plugs from a cold engine.
