✍️ Sample ADT Questions & Answers
1. Under OSHA standards, when a technician is working under a vehicle supported only by a floor jack, what additional safety measure is mandatory?
OSHA requires that vehicles lifted with a floor jack must also be supported by appropriately rated jack stands placed at manufacturer-designated lift points to prevent collapse.
2. When measuring voltage drop across a ground connection in an Audi, what is the maximum acceptable voltage drop?
A voltage drop greater than 0.1V across a ground connection indicates excessive resistance that can cause electrical faults.
3. An Audi S-tronic (7-speed dry clutch DSG) exhibits slow or hesitant engagement from a stop. No DTCs are present. What is the most appropriate first action?
Dry-clutch S-tronic transmissions require periodic clutch adaptation via ODIS Basic Settings to relearn the engagement point, especially after battery disconnection or software updates.
4. A technician is about to replace a front seat containing an integrated seat-mounted side airbag on an Audi. What is the FIRST step?
The first and most critical step is to disconnect the battery and observe the mandatory wait time (minimum 10 minutes) before touching any SRS components to allow the system's capacitors to discharge.
5. Which tool is best suited for capturing and displaying live CAN bus waveforms to verify signal integrity and data frame timing on an Audi?
An oscilloscope or dedicated CAN analyzer (such as a PCAN-USB) allows the technician to visualize differential CAN waveforms, verify bit timing, and decode live data frames.
6. Which suspension component helps absorb shocks from road irregularities?
The shock absorber, often working in conjunction with a spring, is a key component of the suspension system designed to dampen oscillations and absorb kinetic energy from road irregularities. It controls the spring's movement, preventing excessive bouncing and ensuring the tires maintain consistent contact with the road. This provides a smoother ride and improved handling.
