  Summary

  Complaint The result from the XENTRY battery test does not match the current state of the battery. Cause The XENTRY battery tester uses the stored on-board electrical system data in the SAM module to access the health of the 12 volt battery. The XENTRY battery test may not take into account a single discharge event because the SAM or EZS cannot record the data if the battery is discharged. Note: A discharged battery does not necessarily need to be replaced. A discharged battery may be recovered with no permanent damage. Remedy 1) If the battery is discharged, charge the battery. Review WS54.00-P-0037B for minimum charger specifications. • Note the amperage difference between trickle (maintainer) chargers of at least 16A and quick chargers of at least 30A. • Review AP54.10-P-5449U. Note when battery is sufficiently charged the charger current is less 5A. 2) While charging the battery, analyze the vehicle data to determine root cause of discharge using the following data points: • NOTE: For guidance on use of the on-board electrical data please review the AKUBIS video titled "New onboard electrical system diagnosis shown on BR 166". The video can be accessed through WIS by following the path WSM--> content by model series --> passenger cars --> ML-Class --> Model 166 --> group 54 --> New onboard electrical system diagnosis. • Refer to the March 2023 PCTT for the video walkthrough of analysis as well as the attachment of the slides to this Li. • Review GF54.10-P-1012A regarding what can cause deep discharge protection to not end a battery draw. • Review SI54.10-P-0024A for proper maintenance of the vehicle. For Star 2 vehicles: -Review FSAM on-board electrical data conspicuous records • NOTE: This data can be found via FSAM N10/6 -> Actual Values -> On-board electrical system -> On-board electrical system data For Star 3 vehicles: -Review N73/3 EZS on-board electrical data conspicuous records • NOTE: This data can be found via EZS N73/3 -> Actual Values -> On-board electrical system -> On-board electrical system data 3) Determine if root cause is due to: • vehicle technical issue? • customer behavior? NOTE: Recommend using battery analysis sheet found in XiW -> Local Contents -> Diagnostic info -> Battery Discharge Worksheet 4) If battery still does not accept charge AND the vehicle does not fall within the parameters of improper maintenance, then create a TIPS case. *IMPORTANT* - If the improper maintenance/use is found during diagnosis, DO NOT open a TIPS case. If a TIPS case is opened, it will be marked 1 star and directed to your assigned FSE for review. TIPS Case must include with the case: • Amperage setting of charger and time battery was on charger • XENTRY Battery Tester results • Voltage of battery taken with multimeter: Do not connect charger while taking measurements • N10/6 FSAM, (N73 or N73/3) and (N73*1 or N73/3*1) • Workshop analysis of conspicuous data • Root cause analysis for battery discharge based on the above documents (technical, customer, etc.) • NOTE: For expedited results when creating a case write customer complaint as "XENTRY Battery Tester implausible".

  Summary

  Complaint Transmission control unit Y3/8n4 (fully integrated transmission control unit (VGS)) not listed in quick test and/or no communication possible with VGS. Cause Transmission control unit Y3/8n4 Remedy For vehicles with 722.9 transmission: Ensure LI54.15-P-057373 is performed before replacing any component parts. After processing and complying with the above document(s): 1. Perform an ignition reset on Y3/8n4 (VGS) 2. Inspect transmission connector for loose connections, damaged wiring or pins and any other concerns If communication with the VGS cannot be established, the complete valve body ('electrohydraulic controller unit (EHS)') must be replaced. Installation of a VGS repair kit is not permitted in this case as it is not possible to transfer the necessary valve characteristics without communication with the original control unit.

  Summary

  Complaint Possible humming noises from the drivetrain in the area of the rear axle, especially during tight cornering in the lower speed range. Remedy Note: Please follow the instructions in this document. The replacement of components (other than those named for processing) is not effective. Remedy: A test drive must be performed. For accurate analysis (localization) of the noise, the "Steelman Chassis Ear" noise diagnosis kit can be used, for example. If the rear axle differential is unambiguously identified as the cause (noise source), the oil must be replaced. Observe the following: 1. Warm up the oil in the differential by means of a short test drive. 2. Drain the oil from the differential and fill it with new oil according to the parts list in the attachment. Please follow the procedure described in AR.35.31-P-0523OLC. Note: To ensure that the differential is drained as completely as possible, both rear wheels should be rotated slowly 2-3 turns while draining. Make sure that as little residual oil as possible remains in the differential. 3. Please advise the customer that in isolated cases the problem may continue to occur for another 30 to 60 miles after the oil has been replaced. If the problem is still present after the appropriate mileage: • Double check the appropriate mileage was driven. • Repeat the flushing and filling procedure a second time, make sure to properly flush all the diff fluid out • If no change after the second flush and additional mileage. replace the rear diff
