Missing OBD port?

**B1TuRBO** · 01-26-2010 02:27 PM

Hey I took my S4 in to get it checked out for the check light light and the guy says he can't find the OBD plug so I look and sure enough I didn't see one either... anyone know why? anyone else had this problem?

Under Dash -or-
Inside Rear Ashtray

Where you looking? It's either to the left and under the steering wheel, or behind the center console near the ashtray.

It may have been pushed back up into the lower dash portion where it mounts.

I was just thinking about this the other day, it is possible that the clip that holds the OBDII port on the knee bolster may have broken and then would be up under the dash, there are a few hidden screws on the knee bolster, take those off and see if it was pushed up underneath the dash.

ok so I checked the rear ash tray for the OBD port and there is the plug where the OBD plugs in but it looks like its just a blank surface at the bottom if you know what I mean is that what its supposed to be like?

That rear port was used on early A4 models, never on an S4 I don't believe. I think yours is stuck up under the knee bolster.

oh ok, I thought that was it since it had a check engine light imprint on it but guess not
thanks for the help ill pull the knee bolster tommorrow and search for it
