UPDATE: The Toyota Fortuner will also get the DPF regeneration switch as part of the August tech change.


Toyota will shortly announce the addition of a diesel particular filter (DPF) regeneration switch for the Landcruiser Prado and HiLux, as part of a rolling technical change on both models.

CarAdvice can exclusively reveal the change, which comes after a surge in complaints about particulate filter issues from Prado and HiLux owners who primarily drive short distances. Toyota is yet to provide comment regarding the complaints, or provide a specific reason for the change.

A diesel particulate filter works by catching harmful diesel particles, storing them and then burning them off at high temperatures as the filter becomes full.

This process requires high exhaust temperatures and can only be actioned when the vehicle is at operating temperature. If a vehicle is primarily driven in and around the city, with limited long-duration driving, the fliter can become clogged, which ultimately leads to a full replacement of the unit being required.

With the entire Landcruiser Prado range and most of the HiLux line-up powered by Toyota's 2.8-litre four-cylinder turbo-diesel engine, this switch will allow the DPF to regenerate (burning off excess diesel particulates) at the driver's convenience, as opposed to at inconvenient intervals.

Drivers will still need to get their car up to operating temperature for the manual regeneration to work, it's worth bearing in mind.

The change is expected to come into full effect from July 2018, with some vehicles already on showroom floors. This spec update comes on top of the ability to option the Toyota Landcruiser Prado without a rear tyre.

It's unclear at the moment whether the seven-seat Fortuner or 2.4-litre diesel HiLux models will get the same technical change, and accompanying manual DPF regeneration switch.
