This guide will walk you through the process of finding the Audi S4 B5 Obd2 Location in your vehicle.
Step-by-Step Guide to Accessing the OBD2 Port in an Audi S4 B5
The OBD2 port in the Audi S4 B5 is strategically placed for relatively easy access, but it does require a few interior trim pieces to be removed. Follow these steps to locate it:
-
Prepare the Center Console Area: Begin by accessing the center console. First, unscrew and remove the shift knob. Then, gently pop off the center console trim piece surrounding the shifter. This piece is usually held in place by clips. Carefully lift it up and set it aside in a safe location.
-
Remove the Ashtray and Cup Holder: Next, locate and remove the rear ashtray and the cup holder insert in the center console extension. These components typically pull straight out or may have a release clip. Removing these will expose the fasteners underneath.
-
Unbolt the Center Console Extension: With the ashtray and cup holder removed, you will see three identical 13mm bolts. Use a 13mm socket wrench to unscrew and remove these bolts. These bolts secure the center console extension.
-
Detach the E-Brake Handle Section: Carefully inspect the e-brake handle base. There is a clip located underneath it. Unhook this clip to release the e-brake handle trim. Be cautious as this clip can be fragile. Once unclipped, disconnect the two wires that are connected in this area. After disconnecting the wires and clip, the center console extension can be removed and placed aside.
-
Access the Under-Steering Wheel Panel: Now, move to the driver’s side footwell. Tilt the driver’s seat back to provide more working space. Open the driver’s side door to access the side panel of the dashboard. Open this side panel and locate and unbolt the lower 8mm bolt that secures the interior panel beneath the steering wheel.
-
Remove Steering Wheel Column Covers: Locate the plastic covers on both sides of the steering wheel column. Use a small screwdriver to uncap these covers. Behind these caps, you will find 8mm bolts. Undo these bolts. There is also an additional 8mm bolt located on the lower right side of the under-steering wheel panel. Remove this bolt as well.
-
Detach the Under-Steering Wheel Panel: After removing all the bolts, gently pull back on the under-steering wheel panel. It should detach and come off. Be mindful of any clips that might be holding it in place.
-
Locate the OBD2 Port: Once the under-steering wheel panel is removed, the OBD2 port will be visible. It is typically located on the underside of the dashboard, to the left of the steering column. It’s a 16-pin trapezoidal connector.
