Smart Car Clutch Actuator + Gear Actuator Repairs

Smart Car Gear Actuator Faults

The SMART car transmission is unlike any ordinary 5 or 6-speed automatic. It is an automated manual gearbox. Which means the vehicle can be driven as a manual or automatic at the flick of a button. The vehicle does not have a clutch pedal and instead operates on sensors and ECU’s.

The system consists of a clutch actuator assembly, a gear shift actuator assembly, and a gearbox ECU. Each of the actuators will also have position sensors. Which sends signals back to the gearbox ECU to determine which gear the vehicle is in or what position the clutch is in. This information along with vehicle speed and other parameters will be used by the gearbox ECU. To calculate the required gear, when the next gear change should take place and when to engage/disengage the clutch.

As many SMART car owners are already aware, this design has many faults and can render the vehicle completely un-drivable.

Common Clutch + Gear Actuator Problems

When the clutch and gear actuators fail on the Mercedes Smart car. It doesn’t always give the same symptom. Below we’ve listed the most common fault symptoms we are aware of so far:

  • 3 Bars / Lines Appearing on Gear Change Box
  • Slipping Out of Gears
  • Getting Stuck in Neutral
  • Failing to Select Gears

If your clutch or gear actuator has failed, then you may already be aware of exactly how much it can cost to replace the unit. Each actuator is coded to the vehicle and can cost upwards of £700+Vat each to replace with coding. Furthermore, the replacement unit will only come with a standard 12-month warranty and being that it is such a common failing part, it doesn’t give much confidence that the problem won’t re-occur.

We receive clutch & gear actuators for repair on a daily basis for the following vehicles:

  • Smart City
  • Smart ForTwo
  • Smart ForFour
  • Smart Roadster

We have also compiled a short list of part numbers associated to the failing clutch & gear actuator units. Note: this is not a complete list of part numbers, only the most common part numbers we frequently see in our workshops are listed.
