smg hydraulic pump e46 m3 price

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.

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.

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.

In most cases the reason for this is because of worn electric motor, which drives the hydraulic pump in the hydraulic unit. In addition, the gap losses in the hydraulic system increase enormously at high temperatures. If many hydraulic consumers are now active (clutch slave cylinder and transmission actuator), the hydraulic unit can no longer keep up with the pressure build-up. We have ours for that Burkhart Engineering High performance hydraulic oil developed. The required system pressure we up to 25% faster built up than is the case with the normal pentosine CHF 11s.

The worn original engine can "Plug & Play" exchanged for our repair engine. The replacement engine is equipped with the required pins and seals and can be pinned directly into the original BMW wiring harness. It is a replacement part OEM quality. The alternative to avoid having to buy a new hydraulic unit.

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.

I get a lot of negative comments and questions about the SMG gearbox in my E46 M3, but mostly from people who know nothing about them. So I decided to settle a few rumours by explaining a little more about it and why I opted to buy it.

The most common question I get is: “How many times has it broken?” usually followed by: “…and isn’t it about £3500 ($4700) to repair it when it does break?” Truth be told, yes I did once get a fault but it was a sensor switch on the side of the gearbox. The car ran in limp mode and it cost me me £18.75 to fix. Other than that, my SMG gearbox has currently survived for over 13 years and 140,000 miles, and has outlived an engine. I have a few friends who also drive SMG M3s, and guess what, theirs aren’t broken either!

A few years ago I used to run a track day company, which offered advanced driver tuition to people who would bring their own cars to racetracks around the UK. The E46 M3 is a very common car of choice for track day drivers, and I was finding myself behind the wheel of at least two almost every week. I loved the manual, but the SMG felt so captivating with the paddles and fast shifting when on track. To me, it just felt more special than the manual, and that’s what prompted me to buy one.

A: First thing’s first, no, it absolutely, definitely is not automatic. The car does not automatically start moving forward when you take your foot off the brake pedal and the car does not shift up the gears for you if you forget to pull the up-shift paddle either. It really will just bounce off the rev limiter. SMG stands for Sequential Manual Gearbox. It’s actually the same manual gearbox that is found in the cars with a clutch pedal, but instead of having the clutch foot operated, it has the clutch electro-hydaulically operated via a pump and wired to computers. I want to say it’s similar to Lamborghini’s original E-Gear system, but I don’t know enough about Lamborghini’s system to say for sure (please chime in if you know). With the exception of a few software updates (and an extra gear), it’s also pretty much the same Sequential Manual Gearbox offered in the E60 M5 and E63 M6, but yet they don’t seem to get the same hate.

A: Independent testing actually suggests that in the most aggressive S6 setting, it shifts faster than even the fastest manual driver. However, real world comparisons tends to have SMG and manual cars neck and neck. So yeah, pretty much.

A: Because when the system does have issues it’s headache inducing and wallet draining. However, problems are always easier to understand when investigated and broken down (as opposed to pointing in the general direction of an SMG and simply saying “all that is one big mess”).

The transmission itself usually holds up fine; it’s the hydraulic pump, the solenoids, and the relays that fail (and if you really want to get technical, the pumps tend to hold up fine, it’s the motors within that fail). These items can get expensive.

A: That’s all opinion. Would you think the 458 Italia and 991 GT3 are also cars that aren’t involving? I drive both a manual car and an SMG car and I find the SMG car to be fun in very different way.

2001-2006 E46 BMW M3 SMG Gear Shift Hydraulic pump / accumulator. Removed from a 2002 E46 M3 with the SMG transmission and 122k 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 however there is a few spots of corrosion in the housing due to age as shown. 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.

It doesn"t matter. 10 hours is a complete rip off. I can"t even imagine what on earth could possibly take 10 hours. I"ve had my SMG pump out at least 5 times and have relocated it to the drug bin. There is absolutely nothing that could warrant ten hours.
