Diagnostic port not working....

[VAGMAN2]

Tried plugging in 2 fault codes readers and niether can communicate with the car (both DEFINITELY work). I checked the fuse and that's ok, and al the wires going in to the diagnostic port are intact.

So not sure where to go from here.....?

btw it's a 2000 A3 with OBD2.

could be that the car battery doesn't have enough charge: was an issue for me. driving her around and getting the battery upto 12v did the job.

Looks like the battery/power level was the issue - thanks!
