- Complaint resolved until next required time change!
- Customer does not have any navigation function restrictions! - The date cannot be changed!
It is unfortunately not a fix for the date issue. If one reads the logs of the navigation system, it fills up quickly with "EPOCH time is more than one week off."I feel if they really want to fix this for their customers, they will release a telematics update and fix the defective software.








Can you please help me get a VMI?
Does Model Year 2013 have any current issues/Service Bulletins i should have addressed?
thanks so much in advance




Thanks again!
- Campaign No. 2019040001 - Update engine electronics (ME-SFI) control unit software.
LI46.35-P-071462 JUL20 – All models w/electric steering knocking noises when driving or steering, check wear of tie rod inner joint.
LI33.30-P-056665 SEPT20 – All Mercedes-Benz cars with front-wheel drive and 4x4 vehicles single throttle lift-off clunking noise from the side shaft when moving off (audible at the outboard end). The clunk is heard once when changing from forward to reverse (and vice versa). If the complaint is eliminated by experimentally loosening the outboard collar nut (by 1 turn), the problem is due to micromovement in the connection between the wheel bearing inner race and the joint housing of the side shaft. The collar nut must always be replaced after being loosened and must be tightened to the specified torque. Coat contact surface of side shaft with wheel bearing with Molykote paint (MB part # 0009890152).
LI27.50-P-049281 SEPT20 – 722.9 transmission when changing gear range from P to D, harsh engagement may be noticeable, engagement sequences for N-D and N-R must be taught in again as follows (always remain in the gear ranges N/R/D for at least 5 sec): start the engine from cold, shift 5 times N-R, shift 5 times N-D -> warm up transmission to 40°C and while doing so, exceed a speed of 30 mph at least once. Shift 5 times N-R, shift 5 times N-D -> warm up transmission to 70°C and while doing so, exceed a speed of 30 mph at least once. Shift 5 times N-R, shift 5 times N-D.
