Anybody know where the diagnostic port fuse is? My vag com won't work anymore - led on interface doesn't come on and its been suggested that fuse to port may have blown.
Thanks in advance.
Not sure how far this will help as it involves trying to read modern wiring diagrams.
The socket appears to connect to three fuses, numbers 2,12 & 28. It also has an earth connection and connects to a relay 2 on the onboard supply control unit.
Hopefully your problem relates to one of the fuses.
