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.

The Wacker Neuson / Deutz DEF Head Unit OEM 5200017017 serves one main overarching function: to act as the sensor and control hub for the Diesel Exhaust Fluid (DEF) system in Deutz-powered equipment made by Wacker Neuson (2013–2024).
Concretely, its roles include:
-
Monitor DEF level
-
It senses how much fluid remains in the tank and provides that data to the engine’s control system so the system knows when the tank is low.
-
Measure fluid temperature
-
It detects the temperature of the DEF, helping prevent freezing or operating out of specification.
-
Manage fluid flow / act as a header
-
It provides the pickup (suction) path to draw DEF into the dosing / injection system, and possibly a return path for unused fluid.
-
Filter & protect
-
It houses internal filtration (strainers / screens) to block particles, crystals or debris from contaminating the dosing path.
-
Signal and communication interface
-
It relays sensor information (level, temperature, etc.) to the engine control module (ECM) or DEF controller so that the system can make decisions (when to dose, regenerate, issue warnings).
The main function of OEM 5200017017 is to provide real-time sensing, routing, protection, and communication for the DEF system—ensuring the aftertreatment system operates correctly, reliably, and in compliance with emissions rules.
The DEF (Diesel Exhaust Fluid) Head Unit is responsible for monitoring the DEF level, quality, and temperature in your vehicle’s emissions system. When it starts to fail, it can trigger warning lights, fault codes, and even derate mode — limiting your speed and operation. Knowing what to do right away can help you avoid downtime and costly repairs.
Signs Your DEF Head Unit May Be Failing
Watch for these common warning indicators:
- DEF system fault codes or warning messages on the dashboard
- Incorrect DEF readings, such as showing empty when the tank is full
- Check engine light tied to emissions issues
- Premature derate countdown, restricting power and speed
- Fluctuating or inconsistent sensor readings
What to Do if You Suspect Failure
- Do not ignore the warnings. Continuing to drive can cause the system to enter full derate mode, leaving you limited to low speeds.
- Inspect the DEF system. Check for contamination, leaks, or crystallization in the DEF tank that could cause sensor errors.
- Scan for fault codes. Use a diagnostic tool to confirm whether the issue is with the head unit or another DEF component.
- Check electrical connections. Corroded or loose connectors can mimic head unit failure.
- Replace the DEF Head Unit if confirmed faulty. These units are sealed components and cannot be cleaned or repaired. Replacement is the only reliable fix.
How to Prevent Future Failures
- Always use fresh, certified DEF fluid.
- Keep DEF containers sealed and clean.
- Avoid extreme temperatures that cause crystallization.
- Inspect the system regularly as part of routine maintenance.
If your DEF Head Unit is failing, act quickly to prevent derate mode and emissions compliance issues. A prompt diagnosis and replacement will keep your truck running efficiently, avoid downtime, and maintain system reliability.
Common symptoms include DEF gauge errors, incorrect readings, or derate warnings.
Yes, it includes sensors for DEF level, temperature, and quality monitoring.
