B6 RELAY ASSIGNMENT
Relay positions on relay carriers under driver side dash panel
The relay assignment varies slightly with model and equipment level. It also varies slightly with year of manufacture.
This example seems to be a common arrangement on the Passat.
VW often refer to relays by name and various numbers. E.g. Terminal 15 relay. J329. 15/460. This is not a part number.
J329 is the circuit diagram/ work shop designation for Terminal 15 relay.
15/460 is shorthand for terminal 15 relay. Relay type being 460.
Relays of the same type are interchangeable for testing purposes.
