Technical Background
When performing testing on a battery, ensure that the correct battery type has been selected in the VAS 6161 or
GRX-3000 VAS. Failure to select the correct battery type will lead to incorrect test results and could indicate a
false failure of a good battery.
At this time the following batteries are installed in Volkswagen models:
 Regular (Lead Acid)
 AGM (Absorbent Glass Mat)
 EFB/EFB+ (Enhanced flooded battery)
Note:
Failure to select the correct battery type will lead to incorrect test results and could indicate a false
failure of a good battery.
