Send us your malfunctioning Audi hydraulic pump for rebuild/upgrade service.

1. We rebuild your pump without the valve block for $250
2. We rebuild your pump with the valve block attached for $350
Your pump will be fully rebuilt and will exceed OEM pressure specs by at least 5%. Three years warranty, and you get a pump that is better inside than a new one.
Included in the price is a $100 core deposit. Top Hydraulics sends a rebuilt pump first, then you send back your old one for core refund. The pump is fully rebuilt and exceeds OEM pressure specs by at least 5%. Three years warranty.
