Toyota DPF full issues

Quick guide to DPF in Toyota vehicles

  • What is a DPF
    The Diesel Particulate Filter (DPF) is a device designed to reduce emissions by removing diesel particulate matter or soot as it is commonly refered, from the exhaust gas of a diesel engine.
    These days it is required for all Diesel vehicles to have one in order to meet Euro 5 Emission Standards.
  • What do you require to know about the DPF?
    The DPF has to be cleaned regularly to maintain its performance levels. This process is known as ‘Regeneration’ or a ‘Burn’ and is required when the DPF capacity reaches a predetermined level.  This action is done automatically and is self-managed by the vehicles ECU and it is known as ‘Active Regeneration’. This is performed while you drive automatically.
    In Toyota DPFs are fitted to all diesel; Hilux, Fortuner, RAV4, Land Cruiser Prado and Land Cruiser 200 series.
  • So why Am I having issues with my DPF then?
    Well in some driving conditions the Active Regeneration may not complete properly. These include:
    – Driving at very low speeds (e.g. 20km/h or below).
    – Turning engine on and off frequently (if the engine is not left running for more than 10 minutes at a time).
    So when Active Regeneration, does not occur,  a forced Regeneration may be required to clear the DPF of soot. Please refer to your owner’s manual for more information.

How can JAG automotive solutions help you?

  • A forced regeneration can only be done in two ways:
    1. If you see a DPF warning message on your display or DPF light switches ON and your vehicle is equipped with a DPF system switch then you can initiate a forced regeneration manually.
    2. If you do NOT have a DPF switch and you see a warning message such as “DPF FULL SEE OWNER’S MANUAL” then you are required to drive continously for 20-30 mins. However, if you see the following message “DPF FULL VISIT YOUR DEALER” then you will need to visit your dealer or give us a call, we can help you with this issue for a much smaller fee.

Therefore,  in general if a  ‘flashing DPF light’ or ‘display message referring to an engine service/visit to a Toyota dealer’ means the DPF is fully blocked or has malfunctioned and must be inspected immediately.
