P2CCC Hybrid/EV Battery Pack G Deterioration
P2CCC continues the state-of-health series for sectioned traction batteries in the P2 block: after A (P0A7F) and B to F (P0EDD to P0EE1), section G is the seventh. The controller has concluded that this part of the pack has lost too much usable capacity or power. Audi uses the code on the Q5 PHEV as P2CCC00 for battery group 7 in hybrid battery management unit 008C. Its February 2025 reporting obligation 2076982/1 links the entry to a yellow engine lamp and a too-short displayed electric range and asks for a call to technical assistance before any part is changed; bulletin 2079556/1 of September 2025, covering model years 2020 to 2024, then calls for replacing the module behind the entry. CARB wants faults of individual storage parts such as cells to name the smallest unit a workshop can renew. Section H is P2CCD.
