FAQ

Q1: How do I know if this repair kit fits my injector?
A: This kit is designed specifically for Bosch piezo injectors using the BK2Q-9K546-AG or A2C59517051 valve assembly. Please remove your injector and visually confirm the part number on the valve plate before ordering. This is a precision component and using the wrong kit can cause injector failure.

Q2: What tools are required for installation?
A: Replacing the piezo valve requires specialized tools, including a torque wrench, a micrometer, and a press or specific clamping fixture to avoid damaging the sensitive piezo stack. We strongly recommend installation by a qualified diesel injection technician. Incorrect installation can lead to immediate injector malfunction.

Q3: What is the shelf life of this repair kit?
A: When stored in a clean, dry, and temperature-controlled environment (away from extreme heat or moisture), the kit has an indefinite shelf life. However, for best results, we recommend using the kit within 12 months of purchase to ensure the seals and O-rings have not degraded.
