Question about 2009 Audi A4 1.8T
How do I remove the small gear to replace the drive belt for the water pump on Audi 1.8t 2009 b8
There is a special tool to lock the shaft which drives the water pump, then the small pulley on the end can be removed. You can slide the belt off the water pump pulley with the fins if you are careful, then the belt can be wiggled off the bottom small drive pulley. It can be a bit of a pain but it can be done.

it's not an easy job. and requires removal of many components in the front of the engine. However, you can go the the public libuary an look up a Haynes or Chilton auto repair manual. Good luck and you'll need a good set of tools and this would also be an excellent time to change the timing belt.

relatively easy. just weave the belt over, under and around the pulleys the way its show on the belt patter on the label on the radiator., or make note before pukking off old one. Good luck. Watch the fingers!

The previous solution offered is most likely correct. However, in the event that you discover that the timing belt is not at fault, here are some things to consider:
There is a slight possibility that the spark plugs are not firing. Check your distributor cap and electrical connection to the spark plugs to be sure that current is being delivered to them. A power failure to the spark plugs would exactly mirror these symptoms: A sudden engine failure, but a working electrical system that cranks the engine. The fact that the engine turns over indicates that there is nothing else wrong with the electrical system. With continued attempts to start it, however, the battery will eventually die. Keep an eye on that and make sure you have access to an assisting car or a booster kit in that event.
This brings into question the fuel system. If the engine is attempting to start with no result, it is possible that fuel is not being delivered to the engine cylinders correctly (again, this is also in keeping with the previous solution, so make sure to double check the timing belt first). Possible culprits are: the fuel injectors, the fuel sending unit (fuel pump), or the fuel filter. It is unlikely that the fuel injectors have malfunctioned so quickly and totally. Check your fuel filter first, as it is the easiest of the three to inspect. It is usually located along the fuel line between the gas tank and the engine.
If none of these systems are malfunctioning, you will need to look deeper with the assistance of a qualified technician. Make sure, in any event, to connect your car's OBDII system to a diagnostic utility to read any warnings or alerts that the car's computer is indicating.
Good luck, and post new information about the issue as it becomes available!!

The valve timing must be out. You will need to verify that the timing marks on your camshaft sprocket(s) are set at the correct position when you rotate the engine to the compression stroke on TDC.
