We have redefined U.S. and NATO defense training benchmarks, helped establish NATO interoperability standards, and earned the trust of more than 60 nations and 300 integrators.
We offer more than 30 years of trail-blazing experience in synthetic training, simulations, interoperability, geospatial, data analytics, and AI.
We deliver a comprehensive and growing portfolio of ready-to-go products, services and solutions, as well as custom software that ensure decision advantage and mission success.
If you are experiencing symptoms, follow this testing protocol using a professional-grade diagnostic scanner or standalone bench tester. Step 1: Read the Fault Codes (DTCs)
Despite the extra hardware of an AWD system, I averaged about 29.3 MPG . It's impressive to see performance and frugality coexist so well.
Replace internal gear with an upgraded carbon-fiber or brass gear ($20–$50). Calibration Fails + Smooth Amperage Burnt/Worn out internal clutch plates
Testing the xDrive system often reveals these typical failure points:
Whether you are trying to resolve an uncharacteristic shudder during acceleration, clear a dashboard warning light, or perform a mandatory adaptation after a fluid change, this guide explains everything you need to know about testing and maintaining your xDrive system.
When a new actuator motor or internal gear is installed, the VTG module must learn the physical boundaries of the clutch mechanism. The tester commands the motor to rotate until it hits the mechanical stops, mapping out the precise voltage and rotation angles required to engage and disengage the AWD system. Transfer Case Oil Reset
By pulling up live data on the xDrive tester, you can compare individual wheel speed sensor data down to the km/h. If one axle reads consistently faster than the other on a straight road, tire circumference mismatch is confirmed. Types of xDrive Diagnostic Equipment
The transfer case fluid degrades over time due to heat and clutch friction. The VTG module constantly adjusts clutch pressure to compensate for this degradation. When you change the fluid, you tell the computer, or it will apply the wrong pressure, destroying the new fluid and the clutches.
