In some cases, only one answer will be correct.
However, more than one answer might be correct – or even all of them!
1. How is the air mass metered in the 2.5l R5 TFSI engine?
A Using a hot-film air mass meter.
B Using an air pressure sensor.
C Using two air pressure sensors.
2. How is the oil level of the 2.5l R5 TFSI engine measured/monitored?
A It is measured dynamically by means of a thermal oil level sender (TOLS) while the vehicle is being driven, and a warning is given
when the oil level is low.
B Using a dip stick.
C It is measured by an ultrasound oil sensor (PULS) when the vehicle is at idle and at a standstill, and is displayed via the dash panel
insert or MMI.
3. How are inertial forces balanced in the crank train?
A By a balancer shaft which is integrated in the cylinder block and driven by the secondary drive chain.
B By two counteropposed balancer shafts in a balancer shaft module (oil pan).
C No additional balancing is needed in a five-cylinder inline engine due to its structural design.
4. How is the power steering pump in the Audi TT RS driven?
A By track 1 of the belt drive.
B By track 2 of the belt drive.
C The steering on TT RS is servo assisted.
5. What is the task of the coolant circuit solenoid valve N492?
A To open the additional cooling circuit with auxiliary cooler.
B To control the flow rate in the cooling circuit.
C To close the additional cooling circuit during the engine's warm-up phase.
6. How is power flow established for the reverse gear in manual gearbox 0A6?
A By changing the direction of rotation via output shaft 3.
B By changing the direction of rotation via an idler gear which is fixedly connected to the change gear of the first gear.
C By reversing the direction of rotation via the change gear of the first gear.
