The lock itself rarely fails. The cause of the malfunction is most likely a defect in the contact part of the switch (that is, in the switch itself - it is pressed into a plastic part). After unscrewing the lower steering column trim, you can determine whether there is a defect.
In the housing (3) of the ignition switch, the starter and glow switch (2) is secured with a Phillips-head screw (1).
Removal the starter and glow switch
The ignition switch must be removed by a workshop. To do this, a hole is drilled in a precisely defined place. The locking spring of the lock cylinder can then be removed through it. The switch part at the bottom, in the lock, can be the cause of the malfunction if the contacts are worn out.
Remove the steering column switch.
Use two flat-head screwdrivers to lift the plastic bushing on the steering column.
Remove the Allen screw on the left, near the ignition switch housing clamp: remove the housing from the steering column.
On the back of the ignition switch housing, unscrew the Phillips head screw of the starter and glow switch; remove the switch.
During installation, the working pin of the lock must be correctly fixed in the switch.
Please note: when installing the lock body, the plastic sleeve must be correctly fixed in the support.
Tighten the ignition switch housing screw to a torque of 5-10 Nm after installing the switches.
