Jeep Grand Cherokee 3.0CRD Electronic Turbo Actuator Repairs

Jeep Turbo Actuator FaultsJeep Grand Cherokee Turbo Actuator Problems
The Jeep Grand Cherokee 3.0CRD model manufactured between 2005 – 2011 are fitted with a HELLA electronic turbo actuator (wastegate). The electronic turbo actuator is controlled by the engine ECU and is used to regulate the output boost from the turbocharger by opening/closing the VNT vanes as and when required. When correctly tuned, you can safely increase the boost pressure from the turbocharger whilst simultaneously increasing the economy of the vehicle.

The electronic turbo actuator is an extremely common failing part and the root cause of the failure is most likely due to carbon build up inside the turbo vanes. When carbon builds up inside the vanes they get stuck in whichever position they are – then when the actuator is being told to open the vanes and cannot do so, the gears inside can snap, the motor can burn out and you will end up with a vehicle that is no longer drivable. Some of the most common symptoms of a failed turbo actuator include:

  • Loss of power under acceleration
  • Intermittent loss of power under acceleration
  • Smoking on acceleration
  • Fault codes pointing to turbo actuator
  • Fault Code: 0046 – Control Circuit Performance
  • Fault Code: P0234 – Turbo / Supercharger Overboost
  • Fault Code: P0299 – Turbo / Supercharger Underboost
  • Fault Code: P1033 – Boost Pressure Control Short To B+
  • Actuator arm not moving
  • Engine light on
  • Limp mode

If your vehicle has been diagnosed with a faulty electronic turbo wastegate, your dealer will be quoting you for a very expensive replacement turbocharger which will come with a new electronic turbo actuator. The actuator is not available to buy separately and, therefore, you can expect a bill upwards of £1200 for the new replacement parts which only come with a 12-month warranty.

    • Hi Sandra

      Thanks for the enquiry,

      We’ve often found that the actuator fails due to a faulty turbocharger, so it’s quite possible that both units have failed. We do offer testing and repair services for both the actuator and the turbo – I have sent you an email with full information and pricing for both services.

      Kind Regards
