AUDI Inspection & Quality Control 2 — Questions and Answers
Question 1: During a pre-delivery inspection (PDI) on a new Audi, which system should be checked for proper initialization before handing the vehicle to the customer?
- Tire rotation pattern
- MMI navigation system and driver profile settings (Correct answer)
- Windshield washer fluid concentration only
- Spare tire inflation pressure
Correct answer: MMI navigation system and driver profile settings
MMI initialization and driver profile setup are mandatory PDI steps to ensure all infotainment and personalization functions are operational at delivery.
Question 2: When inspecting an Audi's adaptive air suspension, which measurement is most critical to verify during a static quality check?
- Compressor motor amperage draw
- Ride height at all four corners relative to factory specification (Correct answer)
- Reservoir pressure at maximum load
- Valve block solenoid resistance
Correct answer: Ride height at all four corners relative to factory specification
Ride height at each corner must match Audi's published static specifications to confirm proper air spring function and level control calibration.
Question 3: An Audi technician is performing a brake inspection and notices the brake fluid is brownish. What is the primary concern?
- The fluid has been contaminated with gear oil
- Moisture absorption has lowered the boiling point, risking vapor lock (Correct answer)
- The brake pads are glazed
- The master cylinder bore is worn
Correct answer: Moisture absorption has lowered the boiling point, risking vapor lock
Dark brake fluid indicates moisture contamination that lowers the boiling point, which can cause vapor lock and brake fade under heavy use.
Question 4: Which Audi-specific scan tool function is used to verify that all control modules are running the correct, current software versions during a quality inspection?
- Component activation
- Vehicle system test (VST) / Auto-Scan with version comparison (Correct answer)
- Adaptation reset
- Guided fault finding
Correct answer: Vehicle system test (VST) / Auto-Scan with version comparison
The Auto-Scan function in ODIS-S compares installed software versions against the Audi server database to flag any outdated or mismatched control unit software.
Question 5: During a post-repair quality check, a technician verifies that ADAS features are functioning correctly. Which component most commonly requires recalibration after a windshield replacement on an Audi?
- Rear parking sensors
- Front radar sensor for ACC
- Forward-facing camera for lane assist (Correct answer)
- Blind-spot monitoring radar
Correct answer: Forward-facing camera for lane assist
The forward-facing camera mounted to the windshield must be recalibrated to the correct pitch and yaw angles whenever the windshield is replaced.
Question 6: When conducting a NVH (noise, vibration, harshness) quality inspection on an Audi after a suspension repair, what is the preferred method to isolate a suspected wheel bearing noise?
- Rev the engine in neutral while stationary
- Load the vehicle and drive at highway speed while weaving gently (Correct answer)
- Apply the parking brake while rolling slowly
- Use a rubber mallet to tap each hub
Correct answer: Load the vehicle and drive at highway speed while weaving gently
Gently weaving at highway speed shifts lateral load between bearings, causing a failing bearing to change its noise character and identifying the suspect corner.
Question 7: An Audi A6 returns for a quality re-inspection after an oil change. The technician notices oil droplets on the underside of the engine oil pan. What should be checked first?
- Crankshaft rear main seal
- Oil filter housing O-ring and drain plug torque (Correct answer)
- Camshaft cover gaskets
- Oil cooler lines at the heat exchanger
Correct answer: Oil filter housing O-ring and drain plug torque
The most common sources of post-oil-change leaks are an improperly torqued drain plug or a damaged/unseated oil filter housing O-ring, both directly serviced during the oil change.
