Renew your worn or burn"t out SMG pump with our remanufactured units! Our remanufactured pumps are disassembled, thoroughly cleaned and reassembled with all new components.

This part is listed by BMW as BMW part number 21532229715 (21-53-2-229-715) and is described as SMG Hydraulic Pump with Pressure Accumulator - E46 M3.

The SMG pump on the SMG (sequential manual gearbox) equipped E46 M3 is a very well known failure point. It"s really not a question of IF your SMG pump will suffer a failure, but when. Typically, the SMG pump lasts somewhere in the neighborhood of 100k miles, but they have been known to fail with much less miles.

If your E46 M3 has suffered the dreaded SMG pump failure, you need a new SMG pump. And BimmerWorld has the best price available to assist in getting your E46 M3 back on the road.

Pentosin CHF 11S is a synthetic high performance hydraulic fluid for life-time application in modern vehicle aggregates. Pentosin CHF 11S is especially designed for hydraulics in the automotive industry with the highest technical requirements such as in: power steering, level control, shock absorber, hydro-pneumatic suspension, stability and traction control, hydraulics for convertible tops, central lock systems, etc.

The pump motor drives the gear pump, which generates the pressure for the SMG transmission. Both parts together form the hydraulic pump. Without hydraulic pressure, the transmission cannot perform any action – neither change gears, nor operate the clutch. Therefore, the hydraulic pump is the most important component in the system.

In most cases, it is sufficient to replace only the electric motor, as this is a wearing part. The gear pump fails only very rarely. Another advantage is that when only the pump motor is changed, the hydraulic system does not need to be bled afterwards, unless it has been opened.

2001-2006 E46 BMW M3 SMG Gear Shift Hydraulic pump / accumulator. Removed from a 2005 E46 M3 with the SMG transmission and 121k miles. This assembly includes the hydraulic pump and reservoir that operates the clutch and gear shifting mechanisms on the SMG transmission. Will ONLY fit SMG equipped vehicles. In good working condition, fully tested prior to removal from the vehicles. In good physical condition with no major corrosion or surface rusting. Assembly had no major signs of leaking during operation. Includes everything as shown in the photos. You may need to reuse some of your existing hardware and lines for installation.

Burkhart Engineering, based in southern Germany, is a BMW specialist renowned worldwide for its expertise with the E46 M3 SMG2 transmission system. Through countless repairs and a refreshing approach to the problems the SMG system can present, Burkhart has since developed a range of rebuild kits and upgrades to make SMG ownership a worry-free experience.

The Burkhart Engineering SMG Hydraulic Pump Repair Kit can not only repair your pump, but also improves it to be ready for high temperature track use, traffic jams and hot summer weather.

In most cases this is caused by a worn electric motor, which drives the hydraulic pump in the SMG unit. Further the gap leakage in the hydraulic system increase massively during high temperatures. If additionally many hydraulic consumers are working (clutch slave cylinder and gearbox actuator), the hydraulic unit no longer produces enough pressure – for this issue Burkhart Engineering High Performance Hydraulic Fluid offers a huge improvement.  The pump runs on pressure up to 25% fasterthan using the conventional Pentosin CHF 11s.

The old motor can be replaced by the new one as a plug and play swap. The replacement motor is equipped with the required pins and seals and can be directly installed with the original wiring loom. These are brand new spare parts in OEM quality –  the alternative to save you from buying a complete new SMG hydraulic unit.

This Repair Kit only works if the rest of the hydraulic unit is functional. The accumulator for example needs a defined preload pressure. Should this not be the case, the accumulator has to be replaced, too. In Burkhart Engineering’s SMG-Wiki you can find instructions about how to check the preload pressure in the accumulator.

SMG transmissions are electronically controlled and the clutch pedal is replaced by a series of pumps, accumulators, and hydraulic lines. The main component which makes everything happen is the SMG pump which is a notorious failure item on higher mileage vehicles.

This electric motor drives the clutch hydraulic pump on the SMG transmission. This motor is a common failure item that can cause running issues if not addressed.

When our customer got into hisE46 M3recently and found that it wouldn’t start, a transmission problem was the last thing he suspected to be the culprit. There are many more common causes for a no start – like a dead battery, worn out starter, faulty brake pedal switch, etc.- and after checking the usual suspects and not finding the problem, he had the car towed over to our shop.How does the BMW SMG Transmission work?Just to clarify for those who aren’t familiar with BMW’sSMG transmission, the simplest way to explain it is that it’s neither a conventional “manual” nor “automatic” transmission, but more like a combination of the two. You still change gear much like you would in a conventional standard by using a “stick” of sorts (or by paddles mounted just behind the steering wheel), but there is no clutch pedal. Instead, the clutch is controlled electronically by a computer and actuated by hydraulics.Symptoms and Diagnosis: How to know when an SMG pump has failed and needs to be replaced.When the M3 arrived at the shop, we hooked it up to our computer diagnostics scan tool and found a DTC, or“diagnostic trouble code, “indicating a fault with the Park/Neutral solenoid, which is an integrated component on theSMG hydraulic pump assembly. The SMG pump (pictured below) is similar to an ABS pump in both appearance and function, but controls the hydraulic pressures in the transmission and not the brake system.
