P2458 on Toyota by model: symptoms, diagnosis and fix
The Australian DPF class action concerns certain Hilux, Prado and Fortuner vehicles with 1GD-FTV or 2GD-FTV engines acquired between 1 October 2015 and 23 April 2020. The defective exhaust after-treatment system could cause excessive white smoke, unpleasant exhaust odour, increased fuel use and repeated service visits. An effective repair became available free of charge in May 2020. The High Court's November 2024 judgment remitted assessment of damages; individual eligibility and compensation should be checked against current court notices.
Common Symptoms
- Thick white smoke from the exhaust, especially at idle or low speed
- Strong foul or acrid diesel smell in and around the vehicle
How to Fix
Ask Toyota to check the vehicle's VIN, repair history and applicability of the effective 2020 DPF field fix. Do not infer eligibility solely from registration year, or replace/clean the DPF without diagnosing the system. Follow the vehicle-specific owner's manual and technician instructions for warning lights and regeneration. Check current official class-action notices for any compensation claim.
