122-L4A6G-062017-08-01. Service bulletin. POWER TRAIN:DRIVELINE:DIFFERENTIAL UNIT; POWER TRAIN. Concerns: Rear-differential lock control unit Information: This is to inform you of a voluntary Workshop Campaign on the above-mentioned vehicles. With the current data record for regulating the rear-differential lock, there may be increased wear on the pinion shaft on the servo motor for the rear-differential lock as a result of extreme driving over the service life of the vehicle. This can cause noises and can subsequently impair the function of the rear-differential lock.

Concerns: Rear-differential lock control unit Information: This is to inform you of a voluntary Workshop Campaign on the above-mentioned vehicles. With the current data record for regulating the rear-differential lock, noises ("rattling") can occur in the rear axle area as a result of a certain driving style over the service life of the vehicle. This will not impair the function of the rear-differential lock.

AG02 Stop Sale Campaign/Recall Campaign - Checking Circlip on Bearing Bracket for Pedals Internal tests have shown that a circlip on the bearing bracket for the pedals may have become detached from its locking position as a result of preassembly processes carried out by a supplier. In this case, the bearing pin for the pedals will no longer be secured axially in the bearing bracket and can come out of one of the two bearings over the service life. If the bearing pin is mounted on one side only, brake pedal actuation will be impaired.
