With P0EE0 the controller reports ageing of section E, the fifth part of the traction battery. A section is usually a module or a group of cell blocks with its own monitoring; once its share of the pack has lost too much capacity or become too resistive, the whole battery can no longer reach its rated energy, which shows up first as shorter electric range. Audi is the only maker with published references: on the Q5 PHEV, P0EE000 means battery group 5 in unit 008C, and both the 2025 reporting obligation 2076982 and the module replacement bulletin 2079556 list it, intermittent or static. The first also names P0BBD, a voltage spread beyond the limit, which often goes along with a weak section. Distinguishing feature: only section E is named; sections D and F use P0EDF and P0EE1.

Likely causes

Capacity loss of battery group 5
Cell voltages in the section spread too far (often with P0BBD)
Faulty state-of-health estimate

Symptoms

  • Electric range shown too low
  • Engine warning lamp on
  • Less power in electric mode
