4.9 Klasik Defender: şasi, Td5 elektronik ve transfer boşluğu

Research frame

This is a research heading from the source atlas. The heading alone is not OEM service data or a failure-rate claim; model/generation/market identity, official campaigns and measurement evidence remain separate.

Which systems should be separated?

• HV battery, BMS, isolation, inverter, OBC/DC-DC, 12 V and thermal management are separate evidence chains.
• Do not interpret DPF soot/ash, differential pressure, EGT, NOx, SCR dosing and EGR in isolation.

Evidence collection sequence

1. During READY/charging, monitor pack temperatures, cell delta, isolation, 12 V and charging-power curve together.
2. Compare pressure, temperature, soot load and NOx conversion before/after regeneration in the same drive.

Risk of false generalization

• Displayed range or one SoH value alone does not prove battery health.
