Go Transmissions, and look under Passat B5, as they shared many components with the B6 A4 range.
In the vehicle data section of the service book it says

gearbox: M5S
gearbox code: DUK

Not sure what these mean apart from presumably 'Manual 5 gears'. Nothing like the codes that you say though unless i'm looking in the wrong place. Thanks.
