Toyota Auris
Auris (petrol + hybrid) issues, typical codes and a clean diagnostic flow.
What to expect
- Shares many patterns with Corolla — trims and catalyst monitoring behave similarly.
- Short-trip use increases the chance of P0420 without the catalyst being truly failed.
- Hybrid complaints are best confirmed with live data rather than by feel.

Tip: Include make/model/year/engine and what changed recently (battery, service, fuel, long idle, short trips). That’s where the diagnosis lives.
Trust note: These profiles are designed to narrow possibilities. Confirm with test data (trims, misfire counters, pressure/smoke tests, voltage checks) before buying parts.
