Hi mate, a common failure on VAG cars, I just changed mine yesterday before it fails. If you look at the bulkhead behind the coolant reservoir there's three large electrical connectors. The grey one in the middle is for the crank angle sensor follow the wire and it will lead you to the sensor.

It will be around the oil filter area and is held by one ten mm bolt, I changed mine when I had the oil filter off for better access.
