  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. 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, create a 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 and N73/3 EZS CUL • 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 Headlamps leaking or fogged Cause The fogging of the headlamp is a natural phenomenon which can occur under certain climatic conditions. In contrast to a leaky headlamp, physical fogging does not result in a technical impairment of the headlamp. A leak test must be performed to determine if physical fogging exists or if the headlamp is leaky. Remedy Check for external damage: You can identify a damaged headlamp in the following way: For headlamps with a closed system 1. Check the headlamps for any external damage and check also for correct seating of the Gore-diaphragm/correct latching of the cover caps. 2. If the headlamp exhibits any external damage, replace the headlamp. For headlamps with an open system 1. Check the headlamps for any external damage and seal off the vent, then make sure the cover caps are latched correctly into place. 2. If the headlamp exhibits any external damage, replace the headlamp. Note: External damage to the headlamp does not present a warranty or goodwill case. 1. Clear fogged/condensed LED headlamps and LED rear lamps: 1. Drive the vehicle into the workshop (temperature higher than +18 °C/+64.4°F). Note: Do not perform an engine wash before the defogging test. 2. Switch off the engine and connect battery support via a charger. 3. Open the hood or trunk. 4. Switch on the lights. 5. Leave the vehicle in this state for 60 minutes. 6. Check for formation of condensation, a significant reduction in the formation of condensation must be clearly recognizable (thawing progress). 7. If the condensation has disappeared, nothing else has to be done. Note: If defrosting has been performed, you can skip the first step. 2. Leak test of headlamp with overpressure: • Connect test adapter to pressure tester. (Figure 1) • Check test adapter for leak tightness. To do so, connect plug and coupling (picture 2) and apply a maximum overpressure of 30 mbar. The pressure must remain constant. If the pressure does not remain constant, use a new adapter. • All vents have to be sealed with sealing compound and the existing diaphragm with the stamp (picture 3 [3]). (Picture 4) Make allowance for the different headlamp variants here (there are different outlet openings). • Check if the headlamp needs to be removed to gain access to the diagnostic socket on the headlamp housing. • Plug the adapter onto the diagnostic socket on the headlamp housing. (Picture 5). • Apply a maximum of 30 mbar overpressure to the headlamp housing. Note: If the maximum overpressure of 50 mbar is exceeded the headlamp seal will be damaged (picture 6). • If a pressure drop of less than 10 mbar is measured within 30 seconds, the headlamp is tight and there is natural physical condensation. • If a higher pressure drop than 10 mbar is measured within 30 seconds, the headlamp is leaky. Note: The leaky position can be localized with the aid of soap suds. If the pressure test is not passed, the headlamp is leaky. If the cause cannot be rectified, the headlamp must be replaced. Note: If the headlamp is replaced, no dry packs may be installed on the new replacement headlamp. AR82.10-P-5455WT was created for the pressure test. This AR can be used as a reference manual for all closed headlamps. In the event of an open headlamp system, the vent ducts must be sealed before the pressure test.
