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.

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.

This DEF head unit is suitable for use in Cummins-powered vehicles and equipment operating in both on-highway and off-road environments.
A failed DEF (Diesel Exhaust Fluid) head unit can cause significant issues with a diesel vehicle’s emissions system. The DEF head is responsible for monitoring and regulating the DEF tank’s fluid levels, temperature, and quality. When it fails, the vehicle may enter a derate mode or stop functioning properly to meet EPA emissions standards.
Common Symptoms of a Failed DEF Head Unit:
- Check Engine Light or DEF Warning Light
- These lights may illuminate on the dashboard.
- Incorrect DEF Level Readings
- The system might show the tank as empty or full when it's not.
- Engine Derate or Shutdown Warnings
- The vehicle could restrict speed or show countdown-to-shutdown alerts.
- Failure to Start or Sudden Power Limits
- The truck might not start or will operate under reduced functionality.
- Communication Errors
- Diagnostic tools may indicate loss of signal or data from the DEF system.
- Contaminated or Poor Quality DEF Messages
- Even when using proper fluid, the system may report faults.
It’s important to address DEF head unit issues promptly. Replacing a faulty unit and clearing related codes with a diagnostic tool can restore the system’s function and prevent further downtime or compliance problems.
The ASP4310-6600711 manages diesel exhaust fluid (DEF) level detection, temperature monitoring, suction, and heating in SCR-equipped Cummins systems.
