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.

so 2 weeks ago while driving on the highway my Z4 made a beep and shifted to N even though the car"s SMG was set on D. I shifted car back to N and back to D but nothing. I parked the car on the side, shut if off and turned it back on, the car was able to shift to D again. I then drove maybe 10 meters when the same thign happened again, car shifted to N. Turned off and on car and everything worked fine and that was last time it happened.

So i was like thats alot, $4000 and add to that maybe 1500-2000$ labor... that whole car isn"t worth much more than that. Anyway while flipping through the diagnostic reports I noticed a few pages where the system had mentioned there was a fault in the SMG hydraulic pump and it needed to be replaced. So I asked the dealer employee about it and he made a phonecall and told me that they had forgot to add that to the list of parts. Whats the cost? KD1,300 which is around $4,500!! Thats for the one part and not including labor which is around $700.

I leave the dealer and I"m heading to my office when I get stuck in traffic. From idle I press the gas and the car shivered and vibrated. That hadn"t happened before but I figured I might have had the gear in 3 or something. A few moments later same thing happened and this time car shifted to N again. I shut off car, turned it back on and kept the SMG on manual and drove it back to the office. In manual I didn"t run into any problem but I did feel the RPM"s where acting or sounding a bit weird when shifting.

6. SMG accumulator. Very likely. Im currently thinking that if I replace the accumulator I should probably replace the pump at the same time, I don"t want to go through the same labour costs in 50,000k"s to get the pump replaced.Im planning on owning the car for 3+ years

The shitty bit is you can"t buy the pump without the accumulator, so if the pump goes you are stuck with an extra accumulator that no one wants to buy.

7. SMG pump (there are businesses now overseas that do rewinds of these pumps) A few have attempted a self rewind DIY and failed, as apparently the brushes are quite special so to speak. I can source a rebuilt pump for around 1650 USD. (minus 250USD core exch so 1400). Its a lot less than the $3695.00 + GST by Jeff Gray! BUT is it really worth the risk?

8. hydraulic lines. Hmmmm, there could-well be a bent line...unlikely but possible. but the fact that the issue gets worse when the car gets warmer doesn"t makes sense with that... I would have thought that the warmer the fluid, the easier it would pass thru the lines?

In addition to those 8 points there is another interesting point I was told by Kayne at Kayne Barrie Motorsport. He mentioned that if the SMG system is not calibrated regularly, out of sync gear selection can cause the gear selector forks to wear on one side. If it gets bad enough the gearbox wont be able to hold gears. Im going to check this when the box comes out but its unlikely to be related because of the haydraulic pressure fault and that the symptoms aren"t quite right for it to be this.

If above two shows no signs or wear or damage I would then buy a new pump from the States and replace, sell the SMG pump if it tests okay as a second hand unit with a faulty accumulator - you should get at least US$500 for it ...

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.
