diagnostic power

[barking71]

i have no power to my diagnostic port (1996 a4 1.8)

can anyone teel me where this obtains its power from - would an aftermarket radio even on a 1996 model (as i was led to belive that pre 1997 the radio did not power the diag port) affect this

help pls

How did you verify that there was no power? Did you plug in a diagnostic connector and was it connected to a computer with software (VAG-COM?) running? Had you switched the ignition on so that all the panel warning lights were lit? I don't think the radio has anything to do with the power supply.
