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 DEF (Diesel Exhaust Fluid) head unit is a vital part of the emissions system in modern diesel engines, responsible for monitoring DEF level, temperature, and quality. While designed for durability, many DEF head unit models are prone to certain issues that can lead to system faults, engine derates, and costly repairs if not addressed early.
Common Problems Found in DEF Head Unit Models:
-
Sensor Failures – The level, temperature, or quality sensors inside the head unit may fail over time, causing inaccurate readings or system warnings.
-
Crystallization Build-Up – DEF crystallizes when exposed to air, forming white deposits that can clog sensors and interfere with proper operation.
-
Electrical Connection Issues – Damaged wiring, corroded connectors, or loose plugs can cause intermittent sensor failures or complete loss of signal.
-
Moisture Intrusion – Water entering the head unit due to seal failures or condensation can damage internal electronics.
-
Software Compatibility Problems – Some models may experience firmware glitches or require updates to remain compatible with newer engine control modules.
-
Temperature-Related Failures – Extreme cold or heat can affect sensor accuracy, lead to delayed readings, or permanently damage internal components.
-
Aging Components – Over time, the sensors and circuits inside the DEF head naturally degrade, especially in high-mileage or heavy-duty applications.
While DEF head units are essential for keeping emissions systems compliant, they can develop problems if not properly maintained or monitored. Regular inspections, using clean DEF, protecting electrical connections, and addressing system warnings early can help reduce the likelihood of these common issues and keep your DEF system running reliably.
Incorrect data can trigger system faults, emission warnings, and limit engine operation.
When properly maintained with high-quality DEF, it typically remains functional for several years.
Regular visual inspections for buildup, contamination, and electrical integrity help sustain its accuracy.
Contaminants in DEF can interfere with sensor operation and lead to inaccurate quality and level readings.
