SOURCE: Error Code 0320
The wiring that feeds a signal from the crank position sensor to the computer should be checked first. Disconnecting and reconnecting the wiring connector may help. Without the right diagnostic equipment, it is difficult to determine if the sensor is at fault.

SOURCE: Cam position sensor error.
It's not enough only rebuild yours engine !!!
After new camshaft position sensor instalation and timing perfectly alignment you must scan the engine control computer and erase these error, actually all errors stocked in memory. The best scantool is VAS device used by VW-Audi dealers, VAG-COM by RossTech (cable + software 704.014, 805.01, ... on CD), or also Bosch KTS 540, 570, 670, ...
RESET = erase errors from the engine control computer memory !
Yours engine control computer don't understand if you only replace damaged sensors with new others! Errors still remains in memory affect engine runing!

Yes, the sensor is in small housing the goes in the hole where the distributor used to go. That also drives the oil pump so don't drive it you'll ruin the engine. It's located down under the throttle body, near transmission end of the engine.
