What P2CCD means
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.
P2CCD at a glance
- Check engine lightYes, usually on
- Emissions testCan fail
- Limp modePossible
- Repair difficultyWorkshop only
- Typical labor1 to 8 hours
- Clears after repairAfter a drive cycle
Symptoms of P2CCD
- MIL on
- Shorter electric range
- Less power in electric mode
Common causes of P2CCD
- Most likelyBattery module of group 8 worn out
- PossibleModule aged faster due to heat or uneven cooling
- Less likelyFaulty state-of-health judgement by the battery controller
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of P2CCD means
| P | Powertrain system: engine, fuel system, ignition, emissions and transmission. |
| 2 | Generic code (second SAE range): it means the same on every make. |
| C | Area: hybrid propulsion. |
| CD | The exact fault in that area. |
What to do next
- Note P2CCD and any other codes stored with it: several codes together often point to one cause.
- Check for loose connectors and damaged wiring around the parts the code names.
- Check open recalls for your car: some faults are fixed for free by the dealer. Enter your VIN.
- Clear the code only after the repair. If it comes back, the fault is still there.
Buying a used car? Scan it for stored codes before you pay. A recently cleared memory can hide a problem.
Questions about P2CCD
What does P2CCD mean?
P2CCD means "Hybrid/EV Battery Pack H Deterioration". P2CCD reports that section H, the eighth subdivision of a traction battery, has aged past the limit its controller accepts. It is a generic code, so it means the same on every make.
Is it safe to drive with P2CCD?
Drive gently and only to a workshop. With P2CCD the car can go into limp mode (reduced power) to protect itself.
Will P2CCD fail an emissions test?
Yes, it can. P2CCD is emissions-related, so most inspection programs fail a car while it is stored or while the check engine light is on.
How hard is P2CCD to fix?
Difficulty: workshop only. A typical repair takes 1 to 8 hours of work. This is a job for a workshop.
Will P2CCD clear itself after the repair?
After the repair the car has to complete a drive cycle (a mix of city and highway driving) before the test runs again. Until then the readiness monitor shows "not ready", which can fail an inspection.
