If the BMW 3 E46 does not inadvertently turn on the direction-indicator lamps, it is likely that the contact is closed below the slider. To correct the problem, you must disable the mass, remove the rudder, detach the pillow and the contacts themselves, remove the switch, and clear the turn switch. This can be done using a conventional screwdriver, and it is important not to damage the petals of the shell. Clear the check box, remove the board, and clean the contact neatly, especially the gaps between them. Next, you need to collect all the items in reverse order.
