P064100 doesn't look correct what was used to get this code? All EOBD II Codes are 5 characters starting with a letter B, C, P, U. If I take the 00 of it shows.

VAG Error Code: 17025/4123

EOBD II Error Code: P0641

Fault Location:
Sensor Reference Voltage 'A' - Open Circuit

Possible Cause:
Malfunction Indicator Lamp (MIL)(K83) active.

Fuse(s).
Wiring/Connector(s).
Engine Control Module (ECM)
harness is open or shorted.
Engine Control Module (ECM) circuit poor
electrical connection,
Shorted sensor on 5 volt circuit.
Engine Control
Module (ECM).

When is the code detected?:
The Engine Control
Module (ECM) has detected the sensor 5 volt reference circuit voltage is higher
or lower than expected.

As Keith says, you need to get a proper code read done, I have had similar codes to this recently and as it is vague, the reasons can vary and sometimes I have to use the dealer system ODIS under the Guided Fault Finding function to get to the bottom of the problem.
