DPF Delete Module – Nissan Navara NP300

IMPORTANT:
This module is sold to be fitted to unregistered vehicles for off-road use on private property only. Removal of the DPF is an offence on registered vehicles and will make your vehicle unroadworthy.

DPF Delete module for 2015+ Nissan Navara NP300 with YS23 diesel engine. Used to simulate a valid differential pressure signal after the DPF has been removed, preventing DTC P1453 and limp mode. The ECU thinks the DPF is still fitted and everything is normal.

• No tune or ECU remap required
• The DPF can be refitted and everything returned to standard at any time

It comes in a waterproof enclosure, and is mounted in the engine bay near the brake booster. Wires connect to the MAF sensor and differential pressure sensor. Everything is plug and play – no modification to the vehicles wiring or soldering is required. The MAF sensor signal is not modified, it is only used as an input to the module to generate a valid DPS reading. Mounting bracket and bolts are included.

• No engine light
• No limp mode
• No DPF regens

A DPF delete pipe or gutted DPF must be used with this module. Do not fit this module with the DPF still in place or it will block up.
Any DPF delete pipe will work (including a bashed out DPF).
The EGT sensor must be retained in the delete pipe.
The 2 rubber hoses, steel pipes, and differential pressure sensor are not required.

At AJF 4X4, we understand how important it is to get your gear quickly. We aim to dispatch all orders as fast as possible, with a target delivery timeframe of 3–7 business days once your order has been dispatched.

However, some products are shipped directly from our suppliers. While we work hard to keep our stock levels accurate, there are times when items sell out faster than expected or our suppliers run out before our website can update. In these cases, your order may be placed on backorder, which can take up to eight weeks to arrive depending on the product and supplier.

These delays are outside of our control, and while we always do our best to keep customers informed, we strongly recommend contacting us before placing an order if you need an item urgently or by a specific date.

Please note that we do not offer refunds for change of mind, especially if the shipping policy has not been read prior to purchase. It is the customer’s responsibility to check availability and understand our terms before ordering.

If you call and we are unable to answer, please leave a message, as we are often busy in the workshop or assisting other customers. We will return your call as soon as possible.

Our team will always do everything we can to keep you updated and get your order to you as quickly as possible.
