Only unscrew the mounting screws (32h) until
the fanfare horns and airbag clock spring
contact (A45) can be removed
The fastening bolts also act as protection
against twisting and as an assembly aid.
3
Remove the fanfare horns and airbag clock
spring contact (A45) carefully from the jacket
tube
Installation:
Push on fanfare horns and
airbag clock spring contact (A45) as far as the
stop. In the process the recess must align
with the fixing lug (arrow)
If the clock spring contact twists out of
position, i.e., if the steering joint is removed:
#
Set the clock spring contact to center position
AR46.10-P-0200-01GH
4
Unlock plug and disconnect the connector
(38d) from the fanfare horns and airbag clock

5
Check fanfare horns and airbag clock spring
contact (A45) for damage
Visual inspection
Do not use any oil or grease!
The upper (32f) and lower part (32g) of
the clock spring contact are clipped together
and can only be separated by the effect of
high forces or due to defective assembly. If
the spring contact is assembled incorrectly,
carefully unwind and clip the upper and lower
parts together. Be careful not to trap or bend
the spring contact (32e).
