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).

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 plays a critical role in diesel emission systems by monitoring DEF level, temperature, and quality. While built for durability, DEF head units can fail due to various factors. Understanding what leads to these failures can help prevent costly repairs and keep your emissions system running smoothly.
Common Causes of DEF Head Unit Failures:
-
DEF Fluid Contamination – Dirt, water, or non-compliant DEF can damage internal sensors and block system components.
-
Crystallization Buildup – Exposure to air and temperature fluctuations can cause DEF to crystallize, clogging sensors and impairing functionality.
-
Electrical Failures – Corroded connectors, damaged wiring, or loose connections can disrupt sensor signals and cause unit failure.
-
Extreme Temperatures – Excessive heat can degrade electronic components, while freezing temperatures can damage sensors and housing materials.
-
Sensor Wear Over Time – Like any electronic part, the sensors inside the DEF head unit can degrade with age and use, especially in high-mileage vehicles.
-
Moisture Intrusion – Condensation or leaks can allow moisture inside the head unit, leading to short circuits and sensor malfunctions.
-
Physical Damage – Impacts from road debris, improper installation, or rough handling during service can cause cracks or internal damage.
DEF head unit failures often result from contamination, environmental stress, or aging components. Regular maintenance, using high-quality DEF, and protecting the system from harsh conditions can help extend the life of the DEF head unit and prevent unexpected downtime. Early detection and preventive care are key to keeping your emissions system functioning properly.
Faulty data may trigger DEF system errors, cause engine power restrictions, or lead to non-compliance with emissions regulations.
With proper maintenance and DEF quality, the unit typically remains operational for several years.
Routine inspections for contamination, crystallization, and wiring integrity can help sustain long-term performance.
DEF contamination can introduce impurities that interfere with sensor accuracy and lead to system malfunctions.
