P2CCDHybrid/EV Battery Pack H Deterioration
- Generic OBD-II code · Powertrain
- Turns on the check-engine light
- Matters for the ITP
- Can trigger limp mode
- Needs a drive cycle to confirm a fix
- How the car detects it
- P2CCD reports that section H, the eighth subdivision of a traction battery, has aged past the limit its controller accepts. In practice this code only exists on large packs that the battery management splits into at least eight separately judged groups. Audi's Q5 PHEV is such a case and the only published one: there P2CCD00 stands for battery group 8 in control unit 008C, which makes it the last link of a chain beginning with P0A7F00 for group 1. The 2025 Audi bulletins list it as stored either intermittently or statically, with the MIL on and guided fault finding offering no measure, and prescribe swapping the single module concerned; if more than two modules are named, a technical assistance ticket must come first. Expect less electric range and power. Group 7 is P2CCC, section I would be P2CCE.
- What you may notice
