Mercedes-Benz W245 M266 Ignition Coil | B-Class Twin-Spark Pack Spares

Description

Restore smooth engine acceleration, reliable combustion, and peak fuel efficiency to your multi-purpose vehicle with this premium Mercedes-Benz W245 M266 Ignition Coil (Ignition Module / Coil Pack). Specifically sourced and verified for the first-generation B-Class platform (W245 chassis produced from 2005 to 2011) equipped with the M266 naturally aspirated or turbocharged 4-cylinder petrol engines, this vital ignition component is the definitive solution for vehicles suffering from engine misfires, a shaky or rough idle, heavy fuel consumption, or sudden power loss under acceleration.

The Ignition Coil pack on the M266 engine features a distinct dual-ignition layout (twin-spark tower design). It is responsible for transforming the vehicle’s low 12-volt battery power into the thousands of high-voltage volts needed to jump the gap at the spark plugs, igniting the air-fuel mixture with microsecond precision. On the unique sandwich-floor design of the W245 B-Class, the engine is tilted forward at an angle, placing high thermal and space constraints on the ignition layout. Over years of operational exposure, the extreme under-hood heat cycles can crack the coil’s outer composite insulation shell. These hairline fractures allow the high-voltage current to “leak” or arc onto the engine block instead of reaching the spark plugs. This triggers the “Check Engine” light ($MIL$) on the dashboard and logs diagnostic trouble codes like $P0300$, $P0301$, $P0302$, $P0303$, or $P0304$. Replacing a weak or shorted coil pack instantly eliminates engine hesitations and prevents unburnt fuel from damaging your expensive catalytic converter.

Manufactured with high-purity copper windings and high-grade electromagnetic steel cores, this ignition module is engineered to provide an exceptionally stable voltage output across all RPM ranges. It features the factory-correct low-voltage input connector and dual high-tension ignition lead towers for a direct, bolt-on replacement on the engine block. Trust TP German Auto Spares for fully verified, workshop-tested Mercedes-Benz ignition systems, engine sensors, and mechanical spares that keep your B-Class running smoothly on South African roads.
