What P0EAE means
P0EAE says the compressor current reading is electrically valid but does not fit the operating state, for example a value that does not match motor speed or load. Audi documents the code for the 2016 A3 e-tron: P0EAE00 is stored as a passive or sporadic entry in the Climatronic module J255, the MIL is lit at the request of another module over the vehicle network while the engine module holds no code, and P26FD00 may appear alongside. Audi bulletin 2047037 blames a software calculation error in the compressor self-test and the refrigerant system check; technicians follow the guided test plan, replace the compressor only if it directs them to, and update J255 from software 0510 to 0520. CARB requires A/C components used by other diagnostics to be monitored. Circuit faults of this sensor are P0EAD, P0EAF and P0EB0.
P0EAE at a glance
- Check engine lightYes, usually on
- Emissions testNot an emissions code
- Limp modeNot expected
- Repair difficultyWorkshop only
- Typical labor0.5 to 5 hours
- Clears after repairWhen cleared with a scanner
Symptoms of P0EAE
- MIL on without an engine module fault code
- Air conditioning may or may not be restricted
- Entry stored as passive or sporadic
Common causes of P0EAE
- Most likelyCalculation error in the climate module software (Audi A3 e-tron, update available)
- PossibleDrifting current measurement in the compressor
- Less likelyInternal compressor fault confirmed by the guided test
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of P0EAE means
| P | Powertrain system: engine, fuel system, ignition, emissions and transmission. |
| 0 | Generic code: it means the same on every make (SAE standard). |
| AE | The exact fault in that area. |
What to do next
- Note P0EAE 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 P0EAE
What does P0EAE mean?
P0EAE means "A/C Compressor Motor Current Sensor Range/Performance". P0EAE says the compressor current reading is electrically valid but does not fit the operating state, for example a value that does not match motor speed or load. It is a generic code, so it means the same on every make.
Is it safe to drive with P0EAE?
Usually yes, for a short time, if the check engine light is steady and the car drives normally. If the light flashes or the car runs badly, stop and have it checked.
Will P0EAE fail an emissions test?
P0EAE is not an emissions code, so on its own it usually does not fail an emissions test. Other stored codes or a lit check engine light still can.
How hard is P0EAE to fix?
Difficulty: workshop only. A typical repair takes 0.5 to 5 hours of work. This is a job for a workshop.
Will P0EAE clear itself after the repair?
Clear the code with a scanner after the repair. If the fault is fixed, it does not come back.
