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.
Low severity. Can I keep driving?Yes, you can keep driving. The air conditioning may not work.
Symptoms
- MIL on without an engine module fault code
- Air conditioning may or may not be restricted
- Entry stored as passive or sporadic
Most likely causes
- Calculation error in the climate module software (Audi A3 e-tron, update available)
- Drifting current measurement in the compressor
- Internal compressor fault confirmed by the guided test
What to check, in order
Start with the simplest. You can tick off each step.
What each character of P0EAE means
- P: Powertrain: engine and transmission
- 0: Generic code: same on every make
- E: Subsystem depends on the code range
- AE: Specific fault in that system
Frequently asked questions
Can I keep driving with code P0EAE?
Yes, you can keep driving. The air conditioning may not work.
What causes code P0EAE?
The most common causes are: calculation error in the climate module software (Audi A3 e-tron, update available); drifting current measurement in the compressor; internal compressor fault confirmed by the guided test.
