4.7 Discovery 5 ve Defender L663: Pivi Pro, 48 V, hava süspansiyonu ve arazi sonrası kontrol

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?

• ICE, HV/48 V, 12 V, DC-DC, motor-generator, regeneration and thermal management are layers of one energy chain.
• Do not interpret DPF soot/ash, differential pressure, EGT, NOx, SCR dosing and EGR in isolation.

Evidence collection sequence

1. Compare SoC, cell deviation, DC-DC output, motor torque request, regeneration and ICE engagement conditions in one capture.
2. Compare pressure, temperature, soot load and NOx conversion before/after regeneration in the same drive.

Risk of false generalization

• A single DTC or user symptom is not a parts diagnosis; confirm with measurements and physical evidence.
