Product Information

Panic of traffic jams and stop-and-go operations in your E46 M3 SMG on warm summer days?

The Burkhart Engineering SMG II Hydraulic Unit Repair Kit will make your SMG hydraulic unit (BMW part number 2153229715) ready for the summer again!

Is your SMG warning light iluminating and you see the following error messages stored in the fault memory?

  • 53 (0x35) Print ribbon shortfall HE
  • 55 (0x37) Frequency of switching on hydraulic unit
  • 56 (0x38) Duty cycle of hydraulic unit
  • 57 (0x39) Misuse of hydraulic unit
These faults can be responsible for the following problems;

  • Transmission warning lamp illuminating
  • Engine light illuminating
  • Aisles are taken out
  • Gears can no longer be engaged
In most cases, the reason for this is the worn electric motor that drives the hydraulic pump in the hydraulic unit. In addition, the gap losses in the hydraulic system increase enormously at high temperatures . 

The worn out original motor is exchanged for Burkhart Engineering's "Plug & Play" replacement motor. The new motor is equipped with the required pins and seals and can be pinned directly into the original BMW wiring harness. This motor is OEM quality and help you to aviod the alternative of having to buy a new hydraulic unit worth thousands. The  Burkhart Engineering SMG unlocking tool greatly simplifies the replacement of the electric motor of the SMG II hydraulic unit and allows pins can be pushed out to the rear without damaging the connector or pins.

Further to this, the hydraulic unit may no longer be able to keep up with the pressure build-up. Burkhart Engineering have developed their own high performance hydraulic oil which will keep the pressure built up and react as much as 25% faster than with normal Pentosin CHF 11s.


Important information

Do not operate the motor outside the hydraulic unit. Furthermore, the engine should not be dismantled again after it has been installed. The tight fit of the motor can damage it when it is removed. 

The repair kit can only achieve the desired improvement in an otherwise fully functional unit. If, for example, the piston accumulator has a defect or no longer has the required preload pressure, this must also be replaced. The 'salmon' SMG relay (BMW part number 12631742690) is also highly recommended to be replaced.

My first dealing with Southern BM was a pleasant one. I had some springs and shocks installed and Sean was a delight to deal with. Knowledgeable, helpful and offered solutions when not everything went to plan. I would happily recommend them.
