Replacing Ignition Wires — Model 518i (BMW 5 Series E34)

A new wire of the required length is cut from the coil of wire, after which the tips are put on it. This requires two special BMW devices.

Remove the insulation from the end of the wire to a distance of 6 mm. The cross-section of the wire core is 1.5 mm².



Place the tip on the ignition wire and squeeze the end of the wire with special pliers. The tip should be flush with the wire insulation.

Attention: Before installing the tip on the ignition wire of cylinder 4, it is necessary to put the OME 9 pulse sensor on the wire.

Spray the ignition wire with BMW 121098. Insert the tip together with the ignition wire into the special device, see figure.

Insert the spark plug wire into the spark plug boot or into the RFI suppression connector. The boot should snap onto the wire with an audible click.



Install the ignition wires, connect the ground wire to the battery.
