Category: Tag:


Diagnostic tester VNTT-Pro v4 for calibration / adjustment electronic controls.

The device is essential if you are going to repair the turbocharger with mounted electronic actuators.

What a tester VNTT-PRO is used for?

Tester VNTT-PRO is used to diagnose a condition of electronic controllers (electronic valves, actuators, DC motors) of turbochargers with variable geometry VNT (Variable Nozzle Turbine). These actuators changes vanes in the same way as in turbochargers where these elements are controlled by a vacuum.actuators

In addition to checking for correct operation of electronic controllers, VNTT-PRO tester can perform check of a variable geometry position sensors. Such sensors are used in turbines whose variable geometry is managed using the pneumatic valve. They provide information about the current opening vanes variable geometry.


The tester also has the ability to verify proper operation of the boost pressure control valves.


Tester VNTT-PRO can also be helpful in the process of adjusting the range of variable geometry.

What type of position sensors can be checked using VNTT-PRO?

You are in good hands, all leading manufacturers are included. The tester can check potentiometric sensors and inductive sensors (Hall made by:

Which actuators are supported by VNTT-PRO?

VNTT PRO Tester supports actuators produced by manufacturers such as Hella, Siemens, Mitsubishi, Sonceboz, DENSO, MAHLE. They constitute a significant part of the actuators currently being used in the automotive industry.

1. HELLA Actuators

VNTT Actuator Tester v4 supports drivers that accept control signals of type PWM and CAN, as well as the drivers that do not have their own DC motor control. These are the actuators of the following numbers:

6NW 008 091
6NW 008 412
6NW 009 206
6NW 009 228
6NW 009 420
6NW 009 483
6NW 009 543
6NW 009 550
6NW 009 660
6NW 010 099-01
6NW 010 099-02
6NW 010 430-01
6NW 010 430-03
6NW 010 430-04

Exterior of the HELLA actuators  presents the picture below.


There are two types of these actuators (drivers). Most of the Hella actuators available on the market  are so-called actuators “with electronics”. These are the drivers that have a separate system for controlling DC motors used to move the lever position. Cars fitted with these gears:
– Mercedes,
– Ford 1.8 TDCi and 2.0 TDCi,
– BMW 2.0,
– Jeep Grand Cherokee 3.0 CRD,
– VW Touareg 5.0 TDI V10,
– Nissan Navarra 2.5.

Interior of these drivers presents the image below.

6NW 010 099

As mentioned above, there is another type of actuators made by Hella, the so-called actuators”without electronics.” These are the actuators which do not have control of the electric motor integrated with the controller. The control role in this case is played by the engine control unit. They are used in:
-Audi / VW 2.7 TDI and 3.0 TDI,
– Ford 2.4 BMW X3 2.0.

Interior of these drivers presents the image below.

2. Actuators produced by SIEMENS.

The tester supports all controllers manufactured by Siemens without any exceptions. These drivers are used in:
– Audi / VW 2.7 TDI and 3.0 TDI,
– Mercedes,
– BMW.

Here is how actuator made by this manufacturer look like.



3. Mitsubishi driver support.

The Tester supports all drivers manufactured by Mitsubishi. These drivers are used in BMW 320d, Ford 2.2 TDCi and vehicles with engine made by PSA – 2.2 HDI

The appearance of the sample actuator from the manufacturer is shown in the following picture.

The driver for Ford / PSA

4. Operation drivers Sonceboz

Tester supports drivers manufactured by the Swiss company Sonceboz. These drivers are used among others in LandRover and Mercedes cars.

Appearance of the sample driver from the manufacturer is shown in the following picture.


5. Operation drivers DENSO

Tester supports drivers manufactured by DENSO. These drivers are used among others in the Toyota 1.4 D-4D and 3.0 D-4D.

Appearance examples of drivers for this manufacturer shown in the following picture.

The driver for Toyota 1.4 D-4D

6. Support Drivers MAHLE

Tester supports drivers manufactured by MAHLE. These drivers are used mostly in VW, Skoda with 1.2 TSI engine.

Appearance of the sample driver from the manufacturer shown in the following picture.


How long and which car manufacturers are using controllers in turbochargers?

The process started in 2003. Turbochargers with actuators are widely used in car manufacturers such as Audi, VW, Mercedes, BMW, Ford, Jaguar, Jeep Chrysler, Nissan, Citroen, Chevrolet and others.

What can I check the tester VNTT-PRO?

Tester VNTT-PRO allows you to check:

  1. traffic flow control lever,
  2. resistance movement of the lever,
  3. the range of motion of the lever,
  4. mechanical components and on electronics controller,
  5. DC motor controllers used in turbochargers to change the position of the lever,
  6. correct settings scope of variable geometry,
  7. the proper operation of the position sensor variable geometry,
  8. the proper operation of the controller’s internal temperature sensor (only some drivers Hella)
  9. vacuum regulator valve turbo boost
  10. For drivers made by Hella and Siemens, the tester also allows the identification of the driver or the brand of car it is used in.

According to the assurances of manufacturers of turbochargers, the controller is an integral part of the turbine and as such can not be repaired or exchanged, only the entire turbine. With the tester it is possible to determine, sometimes very prosaic cause of the malfunction  and to attempt to repair.

Who is VNTT-PRO tester for?

Tester VNTT-PRO can be successfully used by the companies involved in the regeneration of turbochargers and in showrooms offering a wide range of repairs in order to diagnose the fault of the turbocharger.

Has the Tester original connectors for drivers?

The tester has connectors for original drivers from Hella, Siemens, Mitsubishi, Mitsubishi (BMW), Sonceboz and MAHLE.

For drivers DENSO and Mitsubishi (Ford / PSA), the connector allowing the driver to be plugged is a universal one.

What kind of power requires a tester?

Tester VNTT-PRO tolerate voltages within a range of 12 to 15V. The voltage source should have a minimum current efficiency of 4A.

Supplied with the tester stabilized power supply is designed to power the tester.

Is it possible to update online?

Yes. Simply plug the tester to the USB port of any PC or laptop that has access to the Internet and run the updater (CD included). Details of the update are provided in the device manual.
