If you or your mechanic have diagnosed a bad pump motor, or your dealer told you that you need a new pump motor p/n 8H0959247B (or 8H0959247A - they interchange), odds are 98% or better that you only need a replacement pump without valve block.

For clarification:  The valve block is the part that all of the hoses connect to.  It is attached to the pump body with a single bolt. 

The default option does not include the valve block.  The valve block rarely fails and yours likely does not need to be replaced.  However, if you would like to order your pump with a rebuilt valve block, select order now with core exchange in the drop down menu above and we will send a rebuilt valve block with your pump for an additional $100.  The photo below shows the pump with valve block attached:A4 pump with valve block

Audi part numbers 8H0 871 611D, 8H0959247B, or similar version (D and B are examples of revision used on the A4, which are all interchangeable - they could also be version A, B, C, or E).

To order a part  that ships from Top Hydraulics' inventory first, select "order now with core exchange" in the drop down menu above for "Order Method". The price now includes a $100 refundable deposit, which you get back in full once we receive a core from you that is not missing components and has not been seriously abused.

Is your convertible top not moving at all, and the pump motor is not running, although you hear the relays clicking next to the pump? This is the most common convertible top pump failure symptom for your Audi .

If you or your mechanic have diagnosed a bad pump motor, or your dealer told you that you need a new pump motor p/n 8H0959247B (or 8H0959247A - they interchange), we can rebuild and upgrade your pump to exceed factory specs for a fraction of the price of a new replacement. If you want to eliminate even the chance that there is a problem with the valve block (the part that all hoses go into - it has three brass colored solenoids on it), then this product listed here is your best choice. It includes the pump with motor (p/n 8H0959247B or 8H0959247A - they interchange) PLUS the valve block attached, which makes this Audi p/n 8HO871611D with the assembly looking as pictured.

Top Hydraulics fully rebuilds and tests your pump before sending it to you. We don't just look for a single fault until we have found it, as a backyard mechanic would do, but we fully disassemble the pump, replace and upgrade every seal, and going through every component of the pump. This includes service and repairs to the electric motor, upgrade of some motor components, resealing of the pump unit, full test of all internal valves and all three-way solenoid valves, inspection of all pump components such as pistons and impellers (replacement if they are not to spec), and extensive testing for output pressure, output flow, long term performance, and thermal behavior. We keep the tolerances so tight that no pump will ship without at least exceeding factory pressure specs by 5%.

Top Hydraulics gives you a three-year warranty on the pump rebuld. Unless we are shipping internationally, where liquids are under high scrutiny, Top Hydraulics will ship the pump filled with fluid and plugged at the fluid ports.

Removal of the pump from the car is easy. Remove the trim panel in the right corner of the trunk to create access. Then unplug the wiring harness, unbolt the pump frame from the chassis (three 13-mm hex nuts), and remove the hoses from the pump.

To remove the hoses from the pump, you simply remove the two 5-mm hex bolts in the manifold plate (the aluminum plate that fastens the hoses to the valve block), pull a little on each individual hose, and then pull all hoses together out of the pump. There will not be a big mess, and all hoses stay confined to the manifold plate, so you need not worry about them getting mixed up...

It is advisable to flush your hydraulic system before you install your freshly rebuilt pump with the new fluid in it. Simply cycle your top and the storage cover manually while the pump is disconnected from the valve block (put a waste container under the valve block). One manual cycle without fluid getting back into the reservoir will expel over 95% of the fluid remaining in the system, which is good enough. Your Audi Cabriolet hydraulics are self-venting. As soon as you have a proper fluid level in the pump's reservoir, the pump can operate again. Air from the cylinders will be expelled back into the reservoir - you will have to top off the reservoir once or twice. While there is air in your cylinders, the top and the storage cover will move down faster than usual. Try to catch them by hand a little the first few times, or simply let go of the convertible top button once they start picking up speed. Almost all air will be out of the system after five cycles. Allow the electric motor to cool down between cycles - it is not made to operate continuously for extended periods.

Cleanliness is very important while dealing with your hydraulic system. Do not allow any dirt to enter the system, and use the proper fluid. For hydraulic fluid, either use Audi fluid, or Mercedes fluid p/n A0009899103, or FeBi 02615, Pentosin CHF202, or Pentosin CHF-11S (or Aral Vitamol in Europe). All these fluids will mix. FeBi 02615 is your least expensive alternative, without any compromise in quality, and with the least offensive odor.

 Shipping inside the US is $15 via USPS Priority Mail.

For international shipping, proceed with placing your order, and wait for the $85 FedEx International shipping option to come up after you have entered your shipping address. We ship internationally via FedEx International Priority, which is typically the fastest shipping service available. We get excellent rates from FedEx on account of the high volume shipped daily, and this is reflected in the low shipping charge from us to you. The return shipment is your responsibility - you may want to shop for the lowest rates. 

Please be sure to drain the pump of all fluid before sending it to us. Wrap in absorbent material and a plastic bag, and buffer the parcel well inside. Feel free to remove the sheet metal mounting bracket from the pump, so that you can easily fit the pump into a Priority Mail Medium Flat Rate Box.
