Testing a Turbo Actuator
You can suspect that you need to test your turbocharger actuator if your turbocharger starts to behave differently.

If your turbocharger starts kicking in at low speeds, or it suddenly stops when your vehicle is at high speeds, your actuator may need to be recalibrated or replaced. To test your turbo actuator, follow these instructions:

1, First, make sure the vehicle is turned off. Then, open the hood and find the engine’s turbocharger. The actuator is a small compartment off to the side of the turbocharger’s body.

2, Press the turbo actuator with your thumb. If your actuator moves just under half an inch, everything is fine. If it moves too much or too easily, you are not getting the full benefits of your turbocharger, and you may need to adjust the actuator. Alternately, ask someone to turn the vehicle on while the hood is open. Watch what the actuator does. Because the vehicle isn’t in motion, the actuator should open (move) to release the extra exhaust, rather than feeding it into the turbocharger.

3, Finally, many vehicles are able to interface with a software package called VCDS, formerly known as VAG-COM or the VAG-COM Diagnostic System. This software is used as a diagnostic tool for vehicles that may be malfunctioning. If you have a copy of VCDS on your computer, use a VAG-COM cable to attach your computer to your vehicle. You should be able to test the turbo actuator using VCDS.

Replacing a turbo Actuator
If your turbo actuator is malfunctioning, you’ll probably need to replace it. To do so, follow these simple steps:

1, Unscrew the bolts holding the actuator in place, and then use a screwdriver to remove the actuator clip. From there, the old actuator should pull easily out of its place.

2, Place the new actuator in, engage the clip, and bolt it in place. As you do so, make sure the length of the new actuator’s arm is the same as that of the old actuator (just screw it to
lengthen or shorten it).

You should be able to replace the turbo actuator without removing the actual turbocharger, and the whole process usually takes about 10 minutes.

Testing a turbo actuator is a good way to make sure that your engine’s turbocharger is behaving optimally. While testing the actuator can involve expensive software, it is just a matter of conducting basic observations. Because it’s such as simple process, if you suspect your turbocharger is malfunctioning, the turbo actuator should be one of the first things you check. And if your actuator is broken, replace it.
