Installation Notes

Verify the vehicle chassis break and pump location before ordering, especially on the 2007 Audi Q7 application. Confirm that the existing setup uses an external mechanical high-pressure pump and compare the original part number before installation. Because no gasket, seal, or tank seal is included, reuse or source the required sealing components separately as specified by the vehicle service procedure.
