Risk of poisoning
caused by inhaling
mercury vapor and by
swallowing/skin contact
with toxic salts and
mercury compoundsEnsure that the working area is
sufficiently ventilated.
82 119 We receive at the diagnostic
centers of the plants more and
more xenon control units and
xenon lamps which are o.k.
To avoid this high number of
problem parts with no
reproducible faults, we would ask
you to use the following
procedure for troubleshooting:
1 Perform diagnosis according to
instructions in WIS.
Model 202, 208, 210AD82.10-P-1001AZ
If the fault cannot be
recognized or the faulty
component determined: ?
2 Interchange the xenon lamps
(right to left).
For the time being do not
replace system components.
If the fault of the xenon lamp
still exists: ?
3 Remove/install/replace xenon
lamp.
If the fault remains in the
headlamp the cause may be the
xenon control unit or a fault on
the vehicle side.
We are aware of the fact that
this procedure may possibly lead
to another stay in the workshop o
f
the vehicle in question.
However, we see no other
alternative if the redebiting of
warranty and goodwill costs is to
be avoided.
