There wont be one. It is fuel injection.
AS41 is the metal the crankcase is made from. It was used in engines up to 1975--when they changed to fuel injection.

If this is a petrol vehicle with K-Jetronic injection (you will see four separate braided fuel hoses, one from the fuel distributor to each injector), there is no timing involved in the injection. Each injector sprays a constant mist of fuel.
The fuel pump is the injection pump located next to the alternator and is run by the timing belt.
FSI stands for Fuel Stratified Injection, which describes the stratified petrol direct injection attained by this engine designed by Volkswagen.
On a bosch CIS or CIS E fuel injection system there is a thermal time switch located on the engine upper radiator coolant hos at the head. This device controls the cold start injector timedto engine temperature, cold engine up to about 10 seconds of injection, hot engine 1 or 2 seconds of injection. This switch is used on many European models (VW, MB, etc.) Since you did not provide a make, year and model of the vehicle this is only a guess.

You don't! Vw's use a CIS fuel injection system (CIS stands for Continuous Injection System), the fuel accumulator holds the fuel pressure when the car is off, so it can start right up when you crank the engine again, since fuel is right there at the nozzle tip of the fuel injectors.
