Hydro Unit aka Hydraulic Pump - BMW E88 1-Series


There are two options for placing your order:

1. (Most affordable) You send in your malfunctioning Hydraulic Pump, and Top Hydraulics rebuilds it.

  • The rebuild includes electric motor replacement or rewinding if necessary, a new high-current relay, service of hydraulic valves, and upgrade of internal seals in the pump to eliminate current or future pressure loss or internal bypass. Three years warranty.


2. (Fastest) Expedited Core Exchange Option where Top Hydraulics ships parts from our inventory first

($650 plus a $300 Refundable Core Charge).

  • Option 2 means that you get a rebuilt & upgraded pump from Top Hydraulics' inventory first, then you ship back your original part for credit of your $300 core refund. Top Hydraulics ships the pump as pictured. You get a pump that has been rebuilt to outlast and outperform OEM.

Order Method:


No sales tax for orders in the USA


We provide world class technical support


3-year standard warranty (should last decades)

Additional cost applies if the reservoir arrives broken or there are parts missing or abused. Corrosion on the motor will not incur a surcharge. Please wrap the pump in absorbent material and put plastic bags around it, buffer your parcel well inside, ideally double-box, and tape up well. Top Hydraulics ships your pump back for $15 via FedEx inside the US, or via FedEx International Priority for $85.

The most common failure symptom on used BMW E88 hydro units is either a gradual loss of pressure and power, or electrical failure on account of water intrusion.

International customers: please select the $85 FedEx International shipping option during checkout - the option will appear after you have entered and saved your shipping address.
