Porsche Cayenne Diagnostic Report

Through our diagnostics process, we confirmed that the underlying issue was an internal insulation fault within the high-voltage hybrid battery pack, specifically affecting the minus side harness stage. The diagnostic process eliminated external system and wiring faults, isolating the failure point as internal to the battery module itself.

Porsche Cayenne Repairs

We performed a high-voltage battery repair which involved removing the battery pack, module-level drying and refurbishment, followed by reconditioning and rebalancing of the underperforming cells. The remediation restored correct insulation and system performance, validated through post-repair functional checks.
