When installing an Audi direct injection fuel injector, what is the correct procedure for the copper sealing ring?

A new copper sealing ring must always be installed with each injector to ensure a proper combustion chamber seal and prevent exhaust gas leaks.
During installation of an Audi Quattro rear differential, what must be done to the output flange bolts?
Answer: Replace with new stretch bolts and torque in sequence
Audi rear differential output flange bolts are single-use stretch bolts that must be replaced and torqued in the correct sequence every time.
When installing an Audi timing chain tensioner, why must the engine be positioned at TDC before removal?
Answer: To avoid valve-to-piston contact if the chain slips
With the engine at TDC, the valves are in a safe position so that accidental chain movement will not cause the valves to contact the pistons.
What is the correct technique for installing an Audi wheel bearing using a hydraulic press?
Answer: Press on the outer race only to seat the bearing into the hub
When pressing a wheel bearing into the hub, force should only be applied to the outer race to prevent loading the bearing balls and damaging the bearing.
When installing an Audi B8 platform control arm, what is the proper torque sequence for the pivot bushing bolt?
Answer: Torque to spec only after the vehicle is at full curb weight
Suspension pivot bushing bolts must be torqued with the vehicle at full curb weight to prevent the rubber bushing from being pre-twisted and failing prematurely.
During installation of an Audi 2.0 TFSI timing belt service kit, when should the tensioner pulley locking pin be removed?
Answer: After installing the belt with the engine at TDC
The tensioner locking pin is removed after the belt is installed with the engine at TDC, allowing the spring-loaded tensioner to automatically apply correct belt tension.
What special tool is required when installing Audi 4.2L FSI V8 camshaft locking plates to prevent camshaft rotation during reassembly?
