Important: Vehicles with ESP and/or fog lights with the function "Cornerlicht" for turning, they are also equipped with an additional steering wheel angle sensor "G85", built into the same housing together with the guide coil spring. The assembly work for both types of return rings is the same.
For better clarity, the return ring has been partially removed in the figure. Remove the switch on the steering column. Insert a screwdriver into the flat hole on the back of the switches and release the retaining tab "arrow C." After releasing the upper "arrow A" and lower "arrow B" clamps, remove the return ring "1" from the switch on the steering column.
Installation is carried out in the reverse order of actions.
