ADT Preventive Maintenance Procedures 2 — Questions and Answers
Question 1: When performing a multi-point inspection on an Audi with the MMI service reminder, which action correctly resets the oil change indicator after service?
- Navigate to MMI > Car > Service & Checks > Oil Level, then confirm reset
- Hold the 0.0/SET button while turning ignition to position II, then release after display flashes
- Access the instrument cluster menu via the left stalk, select 'Service', then select 'Reset' (Correct answer)
- Use VCDS to perform adaptation channel 040 reset in the instrument cluster module
Correct answer: Access the instrument cluster menu via the left stalk, select 'Service', then select 'Reset'
On most Audi models, the service interval is reset through the instrument cluster menu accessed via the left turn stalk button, selecting Service, then confirming the reset.
Question 2: An Audi A4 B9 requires a brake fluid exchange. What is the Audi-specified maximum interval for brake fluid replacement regardless of condition?
- Every 1 year or 15,000 miles
- Every 2 years regardless of mileage (Correct answer)
- Every 3 years or 30,000 miles
- Every 4 years or 60,000 miles
Correct answer: Every 2 years regardless of mileage
Audi specifies brake fluid replacement every 2 years regardless of mileage because brake fluid absorbs moisture over time, lowering its boiling point.
Question 3: Which Audi-approved engine oil specification is required for vehicles equipped with a DPF (Diesel Particulate Filter)?
- VW 502 00 / 505 00
- VW 504 00 / 507 00 (Correct answer)
- VW 500 00 / 501 01
- VW 508 00 / 509 00
Correct answer: VW 504 00 / 507 00
VW 504 00 / 507 00 Low-SAPS oil is required for DPF-equipped diesel engines to prevent filter clogging from ash buildup.
Question 4: During a cabin air filter inspection on an Audi Q7, you notice the filter housing also contains an activated charcoal layer. What additional symptom would indicate the charcoal layer is saturated?
- Reduced A/C cooling performance at idle
- Persistent odors entering the cabin even with recirculation off (Correct answer)
- Increased blower motor current draw
- Fogging of interior windows during defrost mode
Correct answer: Persistent odors entering the cabin even with recirculation off
A saturated activated charcoal layer loses its ability to absorb odors, resulting in external smells entering the cabin despite normal airflow.
Question 5: What is the correct procedure for checking automatic transmission fluid level on an Audi with a sealed ZF 8-speed transmission (ZF 8HP)?
- Check dipstick with engine off and transmission cold
- Check overflow plug with fluid at 35-45°C using VCDS to monitor temperature (Correct answer)
- Remove transmission pan and measure fluid depth with a ruler
- Check sight glass on transmission side cover with engine running in Park
Correct answer: Check overflow plug with fluid at 35-45°C using VCDS to monitor temperature
ZF 8HP transmissions use a fill-to-overflow method requiring the fluid to be at the specified temperature range (35-45°C) verified via VCDS before checking the overflow plug.
Question 6: An Audi technician is performing a coolant flush on a 2.0T TFSI engine. Which coolant specification is required to avoid corrosion of the aluminum components?
- Green silicate-based (IAT) coolant at 50/50 premix
- Blue OAT (Organic Acid Technology) G12+ or G13 coolant (Correct answer)
- Universal HOAT coolant compatible with all metals
- Pink POAT coolant per Audi TPI 2044185
Correct answer: Blue OAT (Organic Acid Technology) G12+ or G13 coolant
Audi specifies G12+, G12++, or G13 OAT-based coolant (typically pink/purple) which provides superior aluminum protection without silicates that can degrade seals.
Question 7: When replacing spark plugs on an Audi 2.0 TFSI EA888 Gen 3 engine, what is the correct torque specification for the spark plugs?
- 10-12 Nm (7-9 ft-lb)
- 15-20 Nm (11-15 ft-lb) (Correct answer)
- 25-30 Nm (18-22 ft-lb)
- 35-40 Nm (26-30 ft-lb)
Correct answer: 15-20 Nm (11-15 ft-lb)
Audi EA888 Gen 3 spark plugs torque to 15-20 Nm; over-torquing can crack the aluminum head threads while under-torquing risks combustion gas leakage.
