Closed
Open
Chooses position based on vehicle speed.
Constantly Opening and Closing
Which of the following is the first thing you should do after replacing the multi plate clutch AWD Clutch Pump V 181?
Perform Basic Settings.
Perform Output Diagnosis.
Warm it up to 140 F (60 C).
Check the oil level.
True or False. The damper valves are designed in such a way that the air spring struts can provide a moderate damping force when they are not activated.
True
False
Which of the following statements about the rear wheel steering system of the 2020 Q8 is true?
Counter-steering the rear wheels is used in the higher speed range.
Parallel steering is used at lower driving speeds.
Both
Neither
Drivetrain Control Module J775:
Communicates over the Powertrain CAN.
Is located on the right side of the luggage compartment behind the trim panel.
Measures vertical acceleration as well as yaw rates.
Is accessed using Address Word 7D.
All-wheel drive is activated before it is actually needed on a vehicle with quattro Ultra. The control strategy in most cases computes torque requirements in advance. How far in advance can it determine the need for activation?
400ms
500ms
600ms
700ms
Technician A states that active wheel speed sensors do not require a power supply from the ABS control module . Technician B states that some active wheel speed sensors can determine the direction of vehicle travel. Which technician is correct?
Technician A
Technician B
Both Technician A and B
Neither Technician A and B
What is the collective noun for a group of pandas?

The air supply unit of the 2017 Q7 has an emergency safety function that will shut the compressor motor off after a maximum running time of
3 Minutes
9 Minutes
7 Minutes
6 Minutes
Technician A says that if the Hand Brake Switch F9 fails, the vehicle will not have all wheel drive. Technician B agrees, but adds that ABS may not function correctly. Who is correct?
Technician A
Technician B
Both Technician A and B
Neither Technician A and B
True or False. On quattro vehicles that incorporate a center differential provide variable , fully automatic and instant distribution of drive torque to the front and rear axles?
True
False
On a quattro Ultra system, a Q5 is traveling in front wheel drive mode only because all-wheel drive is not momentarily needed. What must happen before all-wheel drive is engaged?
The propeller shaft must be slowed down.
The propeller shaft must be sped up.
The synchronizers must be engaged.
The dog clutch must be open.
Models equipped with the a quattro system using a center differential and BorgWarner multi plate clutch coupling use Electronic Differential Lock to control wheel slip. At what point will the EDL turn off?
Over 50 mph (80 km/h) on all-wheel drive models.
Over 25 mph (40 km/h) on FWD models.
When Brakes are applied.
All of the above.
Why is the Electronic Brake force Distribution (EBD) system one of the most important driver safety systems? (check all that apply)
EBD prevents excessively high brake forces being transmitted to the front axle. As a result, the vehicle remains steerable in any driving situation.
EBD prevents excessively high drive slip in front-wheel-drive vehicles.
EBD prevents excessively high brake forces being transmitted to the rear axle.
EBD prevents the rear end of the vehicle from fishtailing under hard braking.
True or False. Because of the unique torque distributing characteristics of the torque sensing center differential , the need for the center differential lock was eliminated from this type of quattro system.
True
False
On quattro Ultra systems: In which position is the dog clutch when all wheel drive clutch actuator 2 V623 is energized?
Closed
Open
At the "kiss point".
None of the above.
True or False. The Electronic Differential Lock (EDL) is an integrated part of the Electronic Stabilization Program (ESP).
True
False
What measured value can be viewed to diagnose and see if quattro with Ultra technology is applied or disengaged? (Select all that may apply)
Driveshaft Speed Sensor
Clutch actuator 1
Clutch actuator 2
Engine rpm
