Audi Q7 Diagnostic Report

A customer’s Audi Q7 presented with a Audi Q7 with low range fault: despite a full charge, the vehicle achieved only around 5 miles of electric range. Diagnostic scanning revealed code BECM-P03E800 indicating hybrid battery pack voltage variation. Further inspection located a faulty/unstable module (cell block 48) within the high-voltage battery pack. This enabled a targeted repair solution.

Audi Q7 Repairs

The repair process involved replacement of the defective battery cell block within the high-voltage pack. After module replacement, system recalibrations and safety verifications were performed. Subsequent testing confirmed the battery pack’s voltage stability and restored electric drive capability.

Resolution

Following the intervention, the Audi Q7 with low range issue was successfully resolved. The vehicle’s electric-only range improved significantly (in this case from 5 miles up to 22 miles after repair). Fault codes were cleared and the vehicle’s electric performance restored.
