Mercedes-Benz Ignition Coil M276 V6 & M278 V8 A2769060401 (09-26)

Yes. A worn-out spark plug with a large gap creates enormous electrical resistance, which forces the ignition coil to work much harder to jump the gap. Leaving old spark plugs in the engine is the number one cause of premature ignition coil failure.

Mercedes-Benz ignition coils typically come with a light coating of specialized grease inside the rubber boot from the factory. If you choose to add more, use a very small amount of silicone dielectric grease specifically on the inside lip of the rubber boot to prevent moisture intrusion and make future removal easier.

You will need an OBD2 diagnostic scanner. The code will tell you which cylinder is failing (e.g., P0304 is Cylinder 4). You can test if the coil is the culprit by moving the suspected bad coil to a different cylinder, clearing the codes, and driving the car. If the misfire code follows the coil to the new cylinder, the coil is definitively bad.
