Smart fortwo 451 gearbox control units in stock

The second-generation Smart fortwo (451) had an automated manual gearbox controlled by a Mitsubishi Electric module. Different engine versions use different control units, so the number on the label matters more than the model year. Smart engine control units are in the Smart engine control units category.

Numbers in stock

A4515458132G2T60171HBZE1.0 petrol (45 / 52 kW)

The Mercedes-Benz number may be written with spaces (e.g. A 001 545 71 16) or with the suffix /000 – it is the same number.

Fault symptoms

  • the gearbox does not change gear or stays in neutral,
  • gearbox limp mode and fault message,
  • no communication with the gearbox control unit.

In the Smart 451, similar symptoms are often caused by the clutch or gear-shift actuator – have the system diagnosed before you buy.

Testing, warranty and delivery

Every gearbox control unit is bench-tested before dispatch. We sell it with a 6-month warranty. Details: returns and complaints, delivery times and costs, payment methods.

Can't find your number?

Send us a photo of the entire label on your original gearbox control unit, your VIN and details of the engine and gearbox. We will check compatibility and availability.

Which numbers should I compare? The Mercedes-Benz / Smart number (e.g. A0015457116) and the Mitsubishi number (e.g. G2T60271H4ZE).
Which Smart models are these control units for? For the second-generation Smart fortwo (451).
Are the control units tested? Yes, every control unit is bench-tested before dispatch.

    • Frost, Snow and Moisture: Why Do ECU, BCM and ABS Pump Faults Occur in Winter?

      ECU Diagnostics and Repair 11-10-2026

      Why Do Engine ECU and Vehicle Electronics Faults Occur in Winter?

      ABS and ESP warning lights and the engine management light coming on after a cold night do not necessarily mean that a control unit has failed. Voltage drops, a discharged or ageing battery, moisture or water entering the vehicle’s electronic modules may be the cause.

      In this ECUSale guide, we look at problems affecting engine ECUs in the Audi Q7 and Opel Corsa D 1.3 CDTI, as well as Volkswagen ABS pumps. We also explain how to recognise a water-damaged control module and what to check before replacing it.

      FAQ – Frequently Asked Questions

      1. Are the products tested before shipping?

      Yes, every ECU engine controller, BSI module, BCM module, ABS module, transmission control unit, and other automotive electronic module is electronically tested before shipment. Each unit is checked for proper communication and correct operation to ensure you receive a fully tested product ready for installation.

      2. Does the ECU engine controller require programming or coding after installation?

      Whether programming or coding is required depends on the version of the product. We offer VIRGIN, IMMO OFF, and Plug & Play ECU engine controllers. Information about any required programming or coding is always clearly stated in the product description. In many cases, the unit can be installed and used without any additional coding or adaptation.

      3. How do I choose the correct part for my vehicle?

      The most important step is to compare the part numbers found on your original unit. Pay special attention to the Bosch, Siemens, Magneti Marelli, Continental, or vehicle manufacturer's OEM part number. If you are unsure, simply send us a photo of your existing module or provide your vehicle's VIN, and our specialists will help you identify the correct part.

      4. Are the products covered by a warranty?

      Yes, all ECU engine controllers, ABS modules, BCM modules, BSI modules, transmission control units, and other automotive electronic modules offered in our store are covered by a warranty.
