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 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, 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 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.

A DEF head unit is designed to provide long-term service while monitoring Diesel Exhaust Fluid (DEF) level, temperature, and quality. There is no single replacement interval for every DEF head unit because its lifespan depends on the vehicle, operating conditions, DEF quality, and overall maintenance of the emissions system.
- A properly functioning DEF head unit can often remain in service for several years before replacement becomes necessary.
- Using clean DEF that meets the manufacturer's specifications helps prevent contamination and deposits around the sensors.
- Extreme temperatures and repeated heating and cooling cycles can gradually affect internal sensors and electronics.
- DEF crystallization or contamination inside the tank can interfere with sensor operation and contribute to premature failure.
- Corroded connectors, damaged wiring, or moisture intrusion can shorten the service life of the unit.
- Heavy vibration and demanding operating conditions may accelerate wear on electrical connections and internal components.
- Regular DEF system inspections can help identify inaccurate readings or electrical problems before complete failure occurs.
Rather than replacing a DEF head unit at a specific mileage, its condition should be monitored through routine diagnostics and maintenance. Using quality DEF and addressing warning lights or sensor faults promptly can help maximize its service life and maintain reliable SCR system operation.
Yes. A sensor, wiring, or connection problem can cause the system to report an incorrect DEF condition even when the tank contains sufficient fluid. Diagnostic testing should be performed to determine the cause.
Inconsistent readings can result from internal sensor wear, loose connectors, damaged wiring, corrosion, or contamination. Inspecting both the unit and its electrical circuit can help isolate the problem.
Yes. If a fuse supplying the DEF monitoring circuit fails, the head unit may stop communicating correctly. The applicable fuses and electrical circuits should be checked during diagnosis.
Moisture can cause corrosion or poor electrical contact at connector terminals. This may produce intermittent sensor readings or emissions-related diagnostic codes.
