Six tabs of evidence
Every value is labelled observed (directly in the export), derived (calculated from observed samples) or inferred (undocumented channel whose meaning was reverse-engineered and cross-checked). Solid line segments are measured; dashed segments bridge periods where the car wasn't reporting.
Overview
Current vehicle snapshot — SoC, range, doors, service due — and headline figures: distance, consumption, energy charged, idle drain, top speed.
Driving & charging
Distance per day reconciled to the odometer, driving heatmap, speed distribution, a charging ledger with estimated kWh and power curves, and a trip ledger.
Battery
Battery evidence matched to the export: charging-energy consistency, SoC, and—when diagnostic channels exist—measured usable capacity, cell imbalance, HV current and a health verdict.
Thermal
Ambient temperature, operating modes, seven thermal sensors as small multiples, coolant flow.
Backend & config
Remote actions, vehicle reports, backend errors, and a decoded configuration snapshot.
Package audit
What VW's own Data Dictionary says exists versus what your export actually contains — the concrete field names and numbers to cite if you complain.
