Instructions for Removing Ignition Coils

Model: BMW Serie 5 E39 - Years 1995-2003
Part: Ignition coil

Perform this maintenance with the engine cold. To access the ignition coils, first remove the protective cover; once the cover is removed, the coils are clearly visible. Disconnect each power connector by releasing the lock on each connector: lifting the lock will automatically disconnect the connector. After disconnecting the connectors, unscrew the mounting bolts of each coil and remove them along with the boot by pulling them upward to access the spark plugs. Repeat the same steps on the other bank of cylinders: before unscrewing and removing the spark plugs, blow into the seats to remove any debris that could fall into the cylinders. Proceed in reverse for the installation of the new spark plugs, screwing them in by hand without exceeding the torque specification, then insert the boot, securing the ignition coil with the screws and reconnecting the connector.
