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, 210	AD82.10-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 of the vehicle in question. However, we see no other alternative if the redebiting of warranty and goodwill costs is to be avoided.
