The Hella style electronic actuators are fitted onto many of the modern diesel turbochargers.

Most commonly used on the Garrett range of turbos, but also on the BorgWarner KKK and Mitsubishi range.

The environment these actuators have to operate is extreme. High temperatures, vibration, water, salt etc all result in harsh operating circumstances. Coupled with sticking turbocharger vane assemblies (VNT), blocked DPF filters etc. it’s no surprise these fail.

If you are receiving any of the following common ECU fault codes and limp mode issues, there is a very good chance your turbo actuator is the cause!

• 2510 - Boost Pressure Control
• 3F57 - Charge Air Pressure Controller
• 4191 - Charge Air Pressure Actuator
• P132A - Turbo Charger Boost Control
• P132B - Turbo Boost Control A Performance
• P1952 - Turbo Control Module 1 Defective
• P1953 - Turbo Control Unit 2 Defective

There are of course many other fault codes, and we recommend a detailed inspection to ensure you find the correct cause of your issues.

As part of the turbocharger's "No Repair Policy", replacement actuators are often unavailable to purchase separately, and instead a new turbocharger is required which is a costly repair.

Turbo Rebuild Limited are now pleased to offer an aftermarket replacement.

IDENTIFYING THE CORRECT UNIT

It is important to identify the correct unit to purchase. Many units look identical and the part number are often VERY similar.

1) Firstly find the "G" number, this is found on the side wall off the bottom metal half of the actuator roughly in the middle. From our drop down menu, look for the matching "G" number. (Example as photo "G-013")

2) Next on the top of the black top half of the actuator, look for the number which starts with a 7...  Check this matches the number on the drop down AND the "G" Number (Example as photo "G-013" "763797")

3) Finally again on the top of the black top half of the actuator, look for the number which starts a 6 (located bottom right)  Again, ensure this matches the number on the drop down together with the 2 numbers in step 1 and 2 (Example as photo "G-013, 763797, 6NW009543")

If your selection matches all 3 steps, this is the ideal replacement to your actuator.

If you do not find a match, or are not 100% sure which actuator suits your turbocharger please contact us. 

All of our actuators pass rigorous quality control testing to ensure correct operation, and correct calibration.  Every single actuator upon boxing is tested for operation, position and current draw ensuring perfect operation on the vehicle.

FITMENT:

Only remove the actuator when the engine is cold. Turbochargers get extremely hot and can cause serious burns.

Step 1:  Unplug the power connector by squeezing the side tabs and pulling away from the actuator.

Step 2:  Carefully remove the circlip holding the linkage to the Actuator.  In some instances you may need to remove both circlips from the linkage. Once removed, unhook linkage off actuator.

Step 3:  On the underside of the actuator, remove the 3 bolts with a 10mm spanner

The actuator can now be removed from the turbocharger.

Step 4:  Check the lever of the Turbocharger moves freely to its most extremes without any tight spots "dragging" or sticking.  If the lever does not move freely thorough its whole window of travel, the new actuator must NOT be fitted.  At this point, please contact Turbo Rebuild Limited for advice.

Step 5: Only after confirming the Turbocharger lever moves freely without any sort of restriction, you can mount the new actuator and secure with the 3 10mm bolts.

Step 6:  Refit the actuator linkage securing with original circlip/s

Step 7: Reconnect the actuator plug.

Step 8: With the help of a friend, turn on the ignition of the vehicle, watch for the Turbocharger actuator powering up and completing a full operational sweep.  This should be smooth.  Should clicking or loud humming be found, turn off ignition and contact Turbo Rebuild Limited for advice*

Step 9: The Turbocharger actuator replacement is complete.

*operational sweep may not be carried out on all applications
