Xentry usually doesn't lie. If it sees a short circuit, then it exists. Check all yours when carrying out repair work.

The value is measured by the battery management and is quite reliable. 67 kOhm ist really a bad value and corresponds with a current leakage of 5 - 6 mA. If you are sure that the dc-dc-converter is okay, check all HV-cable contacts you opened. Normally the HV cables are shielded and the shield is pretty good connected to ground. Are there any things in the connectors? Watch on creeping fluids.
