P0A80

A model year appears here because the code is named in its record, not because every one of these vehicles sets it. Counts are mentions in the federal files, not failure rates — nobody publishes the denominator.

Service bulletins and campaigns whose filed summary names P0A80. Quoting the document number at a service desk is often the fastest route to a diagnosis someone has already written down.

• TT: Rev2 A vehicle may arrive to the dealer with a MIL ?ON? condition and P0A80 or P1AC000 stored in the memory. Some cases have been identified with internal modification done to the HV Battery. Modified or altered parts are not covered under warranty.

A stored code names the test that failed, never the part that caused it. It is the starting point of a diagnosis, not its conclusion — the same code has several possible causes and the cheap one is not always right.
