About this part
086959755 Hydraulic Pump Motor — genuine Bosch 12V electric motor for the R-Tronic / E-Gear gearbox hydraulic pump on Audi R8 and Lamborghini Gallardo. New, tested before dispatch.
What it does
The R-Tronic and E-Gear gearboxes are automated manuals: a gear pump builds hydraulic pressure, and that pressure works the clutch and the gear changes. This motor is what drives the pump. Once it wears out the pressure falls away, the pump runs longer and hotter, and the car starts refusing shifts, flashing gearbox warnings or dropping into neutral.
What’s included
- 086959755 electric motor × 1 (genuine Bosch, new)
Why the motor and not the whole pump
In most failures only the motor is worn — brushes, bearings and heat soak. The gear pump itself rarely fails. Swapping just the motor is the standard repair: the original pump body stays, and as long as the hydraulic circuit is not opened there is no bleeding afterwards.
Fitting
Two-pin connector, three mounting tabs, and a drive shaft that couples straight into the pump. Access is from underneath, on the pump assembly. After fitting, run the pump with a diagnostic tool to build pressure and clear the stored faults.
Condition & warranty
Brand-new genuine OEM part, fully tested before dispatch. 12-month warranty.
Fitment
Compatibility depends on model year, market, engine and the coding of the car. The table below lists the applications this 086959755 is normally fitted to. Send us your VIN before ordering and we will confirm fitment for your Audi R8 / Lamborghini Gallardo.
| Make | Model | Years | Fitment note |
|---|---|---|---|
| Audi | R8 (42 / 4S) | 2006 – 2023 | Mid-engine |
| Lamborghini | Gallardo (E-Gear) | 2004 – 2013 | Mid-engine V10 |
Why the index after the part number decides fitment
Volkswagen Group part numbers end in an index letter, and that letter is not cosmetic: it marks a revision. A B revision replaces an A, a C replaces a B, and sometimes a later index will not work in an earlier car because the software or the connector changed at the same time. When a listing shows two numbers separated by a slash, both fit the applications in the table; when it shows one, that is the number we ship. If your old part carries an index we do not list, send us a photo of the label — the number on the part always beats the number in a catalogue.
Ordering more than one
Workshops and resellers order in sets: two of a sensor, four of a camera, a matched pair of modules. We ship from stock and combine postage where the parts are in the same warehouse, and we can quote wholesale pricing for repeat orders. Tell us the quantities and the destination country when you ask, so the shipping figure you get is the real one rather than an estimate.
Fitment check before ordering
Volkswagen Group builds the same looking part in several versions, and the differences are in the number stamped on the housing rather than in the shape. Before you order, compare the number on your old unit with the one in the title — a module that is physically identical but one index out will often fit and power up, then refuse to communicate or code. If you cannot read the old number, send us the VIN and a photo of the connector side and we will identify it for you.
What to expect on delivery
Every unit is checked and photographed before dispatch, packed with foam and shipped with tracking. Electronic parts are tested on a bench where the test is possible without the donor car; where it is not, we say so in the listing rather than promise a test we cannot perform. Keep the packaging until the part is fitted and working.
Shipping, customs and delivery times
Orders leave within one to two working days once payment clears. We ship worldwide with tracking, and the tracking number reaches you by email as soon as the parcel is handed to the carrier. Delivery time depends on the destination and the service chosen — a few days inside Europe, one to three weeks elsewhere — and customs charges, where they apply, are the buyer’s responsibility. If you need a part by a specific date, tell us before ordering and we will confirm what is achievable rather than promise a date we cannot hold.
Returns and warranty claims
If a part arrives damaged, photograph the packaging before opening it fully and contact us the same day. If a part fails inside the twelve-month warranty, send us the fault description and a scan report where you have one — most electronic failures can be diagnosed from the fault memory without returning anything. Parts that have been coded, modified, opened or damaged by incorrect fitting fall outside the warranty, which is why we ask you to read the fitting notes first.
Checking a module before you fit it
Before you install anything, photograph the label on the part you are removing and compare every character with the number in the listing. Plug the new module in, read the fault memory, and only then start coding — if something is wrong, an uncoded module is easy to return and a coded one is not. Keep the original part until the replacement is working; once the car is back together it is the only reference you have.
After fitting
Most electronic modules in this catalogue need coding, adaptation or component protection removal before they work in your car. That work is a paid service quoted separately — we can do it remotely if you have a laptop, a compatible interface and a stable internet connection, or talk your workshop through it. Fitting the part and expecting it to work without coding is the single most common reason a retrofit appears to have failed.
Coding & technical services
Most electronic parts require coding or programming after installation. Remote coding, programming and installation guidance are paid services quoted separately — contact us for a quote.
