SHIPPING POLICY

Tamerx Diesel Products ships via UPS Ground. Next day air shipping can be arranged for a reasonable price of anywhere from $50.00 - $100.00 depending on the weight of the product and your location. We will do everything we can to make sure that you get the service you need. We understand how important it is to receive your order as quickly as possible.
In most cases Tamerx Diesel Products only needs one address, as long as your product is shipping to the same location as your billing information. In order to eliminate credit card fraud, your billing information must match the credit card you provide.

The terms, conditions, and details of our warranty vary from product to product. Specific warranty details can be found below.

Tamerx Diesel Products provides a replacement warranty on all of our parts. The duration and mileage limitations of the warranty vary by product and are specified on the product's detail page/item listing.

Please note that the warranty covers replacement of the part and the cost of shipping the replacement part to you only. It does not cover any shop, labor, towing, or any similar or related costs. This is not a "money back guarantee".

If you experience a problem with your part or it is not functioning properly, the correct warranty procedure is to call us at (510) 257-1777 (8:00 AM - 5:00 PM ET Monday through Friday). Be sure to have your order number and/or other relevant order information ready so we can easily locate your order and resolve your issue as quickly as possible. From that point, we will review with you any troubleshooting steps that may need to be taken and other areas or systems that can be checked to rule out external problems contributing to your part's issue. If a replacement is determined to be necessary, we will then arrange for your replacement part to ship out ASAP and issue any necessary return shipping labels and/or documents.

As is the case for the majority of the diesel products sold on Tamerx Diesel Products, your part's warranty is active as soon as you install it. In some other cases, warranty activation is contingent upon you sending us your core (i.e., your old part). Tamerx Diesel Products will provide you a return shipping label for parts that have a warranty with a core return condition. When we have received your core return, the part's warranty coverage begins. We reserve the right to void the product warranty if your core is not received within the allotted time, or if it isn't received at all. If the warranty for the diesel part you are purchasing has a core return requirement, it will be clearly noted on the product detail page/item listing.

What is a Core Charge?

A core charge (also called "core deposit") is similar to the deposit you might pay for a can or bottle of soda and is a standard requirement in the auto parts industry. For example, in many states, to promote recycling, you pay a deposit when you purchase a can of soda and receive your deposit back when you return the empty can. Many automotive parts have a core charge, or core price, that works in essentially the same way as a soda can deposit.

30 Day Core Charge Hold

You authorize Tamerx Diesel Products, to hold your credit card for the specified core charge amount and that you agree to return your core with 30 days of receiving the purchased part. When we have received your core return, the hold is released and the core charge payment is canceled.

The customer, or parts buyer, is responsible for any shipping costs associated with core returns unless otherwise specified in the product listing/detail page. Tamerx Diesel Products offers prepaid UPS shipping labels (SKU numbers UPS-CR1 and UPS-CR2) for use in returning your core that are available for purchase on our website during your shopping/order process.

The shipping label you will need to use for the core return is dependent upon what part you are purchasing. UPS-CR1 is good for cores weighing up to 20 pounds. UPS-CR2 is appropriate for shipping cores weighing 21 pounds or more. You must include enough information with the core return that clearly identifies it as a.) a Core Return, and b.) contains enough information we can use to clearly associate the core return with your order. Including a copy of the invoice or packing slip that came with the original shipment, clearly marked "Core Return", is ideal. Alternately, you can include a note marked as "Core Return" that includes your order number, full name and address, and phone number or other contact information. Failure to include this information with your returned core will most likely delay any due core credit being issued and/or delay any applicable warranty activation. Core returns need to be for the exact part purchased and cannot be damaged. Substituting another part in place of the part you have purchased is not acceptable.

All fluids must be drained.

If you have purchased a set or a parts package, you will need to return cores for all components of the set. For example, if you have purchaed a high pressure oil pump with an IPR valve, you will need to return both HPOP and IPR valve cores to receive proper credit. If you have purchased an EGR cooler/EGR valve package, your core return must consist of an EGR cooler core and an EGR valve core, or core credit will not be given.

Core Charges are often mandated by state legislature, and, as such, the actual core charge and taxes on the charge may vary depending on the state in which you buy your part. The Tamerx Diesel Products core charge presented to you online today with your item is representative of the most common core charge.

Diesel engines rely on their aftertreatment systems to reduce harmful emissions—especially nitrogen oxides (NOₓ). The DEF Doser Injector (OEM 47511725) for Case IH, New Holland, and Iveco engines (2016–2022) is a critical component of the Selective Catalytic Reduction (SCR) system. It precisely injects the right amount of Diesel Exhaust Fluid into the exhaust stream, helping your engine stay compliant, efficient, and operational without unnecessary downtime.

Why the OEM 47511725 DEF Doser Injector Is Essential:

  • Precise NOₓ Reduction: Optimally meters Diesel Exhaust Fluid (DEF) into the exhaust to ensure efficient NOₓ conversion in the SCR system.

  • SCR System Health: Helps maintain proper regeneration cycles and prevents DEF-related system faults that can cause limp mode or downtime.

  • Seamless OEM Fit: Specifically designed for Case IH / New Holland / Iveco engines (2016–2022), ensuring plug-and-play compatibility.

  • Premium Bosch Quality: Backed by trusted OEM standards, delivering durability and precise dosing under challenging operating conditions.

  • Extended Coverage: Equipped with a generous warranty—one year or one million miles—supporting long-term fleet reliability.


A malfunctioning DEF doser injector can bring your SCR system to a standstill and trigger emission issues. Opting for the OEM 47511725 injector ensures your equipment remains compliant, dependable, and efficient. For reliable OEM-grade replacement parts that keep your engines clean and operational, trust TamerX Diesel Parts—your partner in emissions control solutions.

The DEF (Diesel Exhaust Fluid) doser injector plays a key role in reducing harmful emissions in modern diesel engines. It works by spraying DEF into the exhaust stream, where it reacts with NOₓ gases and converts them into less harmful substances. While it might be tempting to ignore a failing DEF doser injector, continuing to drive with a faulty unit can have serious consequences.

Risks of Driving with a Faulty DEF Doser Injector

  • Check Engine Light or Warning Alerts
    A faulty doser injector will often trigger the check engine light or display SCR system warnings on the dashboard.

  • Emission System Malfunction
    The engine’s Selective Catalytic Reduction (SCR) system relies on the injector to properly dose DEF. If the injector isn’t working, NOₓ emissions won’t be reduced, potentially causing the vehicle to violate emissions regulations.

  • Reduced Engine Power (Derate Mode)
    Many modern diesel engines will enter derate or limp mode when DEF dosing problems are detected. This means reduced engine power and speed limits to protect the system and meet emission laws.

  • Increased Fuel Consumption
    A malfunctioning DEF doser can lead to inefficient combustion, causing the engine control module (ECM) to compensate by adjusting fuel delivery.

  • Potential Fines or Failed Emissions Tests
    Operating a diesel vehicle that’s not meeting emissions standards can result in failed inspections or fines, depending on local laws and regulations.

  • System Damage Over Time
    Continued operation with a faulty injector can affect downstream components like the SCR catalyst and sensors, leading to expensive repairs.

While your vehicle may still operate with a faulty DEF doser injector, doing so is not recommended. Beyond risking reduced performance and potential fines, continued use can lead to damage to the emission control system. It's best to address the issue promptly through diagnostic testing and replacement to keep your engine running clean, compliant, and efficient.

Erratic dosing may trigger derate modes, limp-home protocols, or rough engine running.

Visible DEF residue or salt-like buildup around the injector tip often indicate cleaning is needed.

Ensure the connector is dry, the tip is clear of deposits, and it is securely mounted.

Inconsistent dosing results in fluctuating exhaust temperatures and potential emission spikes.
