REVISION HISTORY
Testing the battery for all 2007 2009 Audi Q7 models must be performed using the VAS 5051, 5051B, or 5052 scan tools. Midtronics Tester printouts are no longer valid for warranty claims.
Charging the battery must be performed with an Audi-approved battery charger. This TSB describes the specific use of the Midtronics Battery Charging Station InCharge 940 (INC-940).
Technical Background
The Battery Data Module J367 is replacing the Battery Energy Manager J644 in the MY 2009 Audi Q7. For the MY 2009 Audi Q7, the procedures for testing a new battery during PDI and testing a used battery with Guided Fault Findings/Guided Functions are different from the procedures for previous model years.
Production Solution
Not applicable.
Service
1. Follow the battery test instructions:
MY 2007 - 2008
^ In GFF: Select Go To >> Function/Component Selection >> Body >> Electrical Equipment >> 01-On Board Diagnostics >> 61-Battery, control >> J644-Energy Management Ctrl. Mo., functions >> A-Battery, testing.
^ In GF: Select 61-Battery control >> A-Battery, testing. Depending on the situation (new battery in PDI or used battery in customer's hand), select the corresponding test.
MY 2009
^ In GFF: Select Go To >> Function/Component Selection >> Service work >> A-Battery, testing.
^ In GF: Select Service work >> A-Battery, testing. Depending on the situation (new battery in PDI or used battery in customer's hand), select the corresponding test.
2. Using the Midtronics Battery Charging Station InCharge 940 (INC-940), connect the positive and negative cables to the corresponding remote jumper posts under the hood on the driver's side.
Note:
Ensure that the charging clamps do not contact each other, as the remote positive and negative jumper posts are located close to one another.
3. Locate the DIN value using one of the following methods:
^ The DIN value appears on top of the battery (Figure 4).
^ In ETKA, type the VIN in the FI SEARCH box and select 9 Electrical systems >> battery. The second value in the REMARKS field of the highlighted battery is the adequate DIN value (450A or 520A).
4. For batteries with DIN value 450, enter DIN value 250 into the charger when requested.
For batteries with DIN value 520, enter DIN value 300 into the charger when requested.
This value difference is due to the Battery Energy Manager (BEM) and added resistance in the system between the battery and remote jumper posts.
