Turbo Electronic Actuator Repair & Testing
The latest method of turbocharger boost control on many of the manufacturers units is via Electronic Turbo Actuator.
Electronic Turbo Actuators are currently the most accurate type of turbocharger boost control and as they are controlled by the engine's ECU, it means that adjustments can be made in tiny increments at any given turbo boost pressure, in any given situation.
The use of the Electronic Turbo Actuator means improved turbo spool up times and increased efficiency, resulting in more power and better fuel economy.
By introducing another electronic control component into already a highly sophisticated system, there are bound to be downsides... in this case, it is faulty turbo Electronic Actuators.
As part of many Turbo Manufacturers "No Repair Policy", if you have a faulty Electronic Turbo Actuator, it would mean you would have to replace the complete Turbocharger as the Turbo Actuator itself will not be available on its own. As you can imagine, this is going to be an expensive repair, but we can offer a solution!
We are able to offer not only Electronic Turbo Actuator testing, but also Electronic Actuator reconditioning to many of the Electronic Actuators on the current range of turbochargers.
Our Turbo Electronic Actuator testing service involves us running your turbocharger's Actuator on our test bed to ensure the Actuator works efficiently without error and that it can reach its full working parameters. All units are delicately cleaned internally to ensure all electrical components are free of dirt which can affect the unit's ability to process information received and also to ensure all moving components are damage free.
We then pack and return to the address of your choice for only £30 inc vat and delivery!
What if the Turbo Electronic Actuator is damaged?
We can recondition many Turbo Electronic Actuators to "as new" condition, overcoming 90% of possible faults. If we cannot repair your unit, we dont charge... simple!
We can reconditon Garrett Electronic Actuators, including replacement Motor and Gear, replacement Actuator Worm Gear and also Circuit Board Repairs. To ensure a quality repair to your actuator we use:
- Genuine Johnson replacement Motor (original replacement)
- High quality plastic replacement Worm Gear (original strength to ensure reliability)
The cost of a recondition to a Turbocharger Electronic Actuator is £125 and includes VAT and return delivery. Turnaround time can vary depending on the fault, but all actuators are ready to return within 10 working days.
We also are increasing our range of exchange Turbo Electronic Actuators which are on the shelf ready to go on an exchange basis. This will greatly reduce the timescales of turbo repairs and can get you back on the road in under 24 hours! Please enquire for availability and terms.
What Electronic Turbo Actuator units can we test?
We can currently test 95% of the current Turbo Electronic actuators in circulation, please see below...

PLEASE NOTE: ALL ACTUATORS EXCEPT THE GARRETT HELLA TYPE REQUIRE CALIBRATING TO YOUR ACTUAL UNIT TO ENSURE BOOST CONTROL IS ACCURATE AND THE VEHICLE IS KEPT IN SAFE PARAMETER. FOR THIS REASON, WE REQUIRE THE COMPLETE TURBOCHARGER AND ACTUATOR IN ORDER FOR US TO CALIBRATE THE ACTUATOR BACK TO YOUR UNIT!
How do I know if my Turbo Electronic Actuator is faulty?
The easiest way to diagnose a faulty Electronic Turbo Actuator is by plugging in fault-finding equipment into the cars OBD plug. However, this fault-finding equipment isn't always required and in some cases is known to give incorrect answers, so a manual test can be undertaken.
- Locate the Turbocharger and the Electronic Turbo Actuator
- Monitor the arm of the Turbo Electonic Actuator as the vehicle engine starts. The arm should move freely to close the VNT mechanism
- Gently rev the engine again whilst watching the Electronic Turbo Actuator arm linkage. The arm should move as the engines RPM rises and drops
If the Turbo Actuator linkage does not move during this test, then we need to confirm if the VNT mechanism is jammed preventing the Electronic Turbo Actuator linkage arm from moving or if is a faulty Electronic Turbo Actuator.
With the the Borg Warner Actuators,and Mitsubishi Electronic Turbo Actuators, the turbo arm linkage can be moved by hand (ensure the vehicle ignition is turned off). Ensuring that the arm travels over the whole operating range without jamming will rule out the Nozzle Ring or VNT are not jammed. On the Garrett Hella Electronic Turbo Actuator, you need to remove a circlip connecting the linkage to the Electronic Turbo Actuator. With the linkage removed from the Turbo Electronic Actuator, move the linkage to open and close the VNT or Nozzle Ring to ensure it operates over its whole working range without sticking. This will rule out the VNT.
By ruling out the Turbo VNT/Nozzle ring sticking we can narrow down the issue to a possible faulty Turbo Electronic Actuator or the Actuator being out of calibration.
Typical fault codes shown on diagnostic equipment pointing towards a faulty Electronic Turbo Actuator include.
These Engine fault codes have been known to point to a faulty Turbo more importantly a faulty Turbo Actuator, but this always isnt the case and testing and further inspection is advised
