Common symptoms of failing ignition coils include engine misfires, rough idling, sudden loss of power, decreased fuel economy, or an illuminated check engine light. For diesel glow plugs, signs include hard starting in cold weather, white smoke from the exhaust upon startup, or rough engine idling until warmed up. Replacing worn parts with a genuine Beru component restores strong spark energy and reliable combustion.

Beru is a renowned tier-one OEM supplier with decades of expertise pioneering cutting-edge ignition and cold-start technologies for major European and global automakers. Choosing Beru ensures factory-level electrical performance and durability.

Ignition coils should be checked whenever a cylinder misfire occurs and are often replaced as sets after 100,000 miles. Diesel glow plugs experience high thermal stress and typically require replacement between 60,000 to 100,000 miles, or whenever cold-start performance degrades.
