Which tool is used to measure the carbon brush length on an Audi alternator without disassembling the unit?
Answer: Vernier caliper
A Vernier caliper can measure external dimensions of accessible brush holders to assess brush wear without full disassembly.
When using an oscilloscope to diagnose an Audi crankshaft position sensor, what waveform pattern indicates a healthy sensor?
Answer: Square wave with consistent frequency and amplitude
A healthy Hall-effect crankshaft position sensor produces a clean, consistent square wave with uniform frequency and amplitude at normal engine speed.
What is the primary purpose of the Audi special tool T40196 used during DSG transmission service?
Answer: Mechatronic unit removal
T40196 is the dedicated mechatronic unit removal and installation tool for the DQ250/DQ500 DSG transmission family.
When pressure-testing an Audi cooling system, which gauge reading indicates a failing head gasket?
Answer: Pressure drops steadily over 10 minutes with no visible external leaks
A steady pressure drop with no visible external leaks indicates coolant is being forced past the head gasket into the combustion chamber.
Which scan tool function allows a technician to check the live response of Audi Adaptive Cruise Control radar sensor alignment?
Answer: Basic settings / guided functions
The Basic Settings or Guided Functions menu in ODIS/VCDS initiates the ACC radar alignment calibration and provides live feedback during the procedure.
An Audi technician uses a UV leak detection lamp after injecting dye into the A/C system. What color indicates a refrigerant leak?
Answer: Green or yellow-green fluorescence
UV-reactive refrigerant dye fluoresces green or yellow-green under UV/black light, making leak points clearly visible.
When using a torque angle gauge (degree wheel) on Audi engine head bolts, what is the correct sequence after applying initial snug torque?
Answer: Apply the specified angle in one continuous motion following the factory sequence
Torque-to-yield head bolts require the angle to be applied in one continuous motion following the manufacturer's tightening sequence to ensure even clamping force.
