1) Check the 12 volt battery for external damage - In the event the battery has external damage - Raise a
Technical DISS query (ensure clear photographs of the damage / issue are attached)
NOTE TO PRODUCT SUPPORT: The DISS query MUST be second levelled to the Electrical Senior
Engineer, await feedback before conducting any further checks
Or
Should no external damage be evident please continue with the remaining steps to completion

2) Carry out the battery Warranty test process as per ElsaPro Rep.Gr 27 - Battery → Battery - To test (VAS
6161). If a battery defect or bad cell is detected a specific warranty code will be displayed on the print out.
The results must be attached to the open DISS query, failure to provide the battery test results will invalidate
the warranty claim

If the message ‘Perform charge acceptance test’ is displayed then refer to Rep.Gr 27 - Battery →
Assessing battery test results → Orig. VW-Batt. Test (Warranty)

trickle charger before replacing the battery
If the ‘Perform charge acceptance test’ fails and no quiescent drain or alternator failure is present, the
battery replacement will not be covered under Warranty as the failure is caused by a maintenance error.
Please advise the customer how to maintain a healthy battery
Consider the advised onward checks to help diagnose the potential battery failure issue
