Locating the Audi S4 Engine Code: Different Approaches

There are several ways to find the engine code on your Audi S4, and the easiest method might depend on the model year and your access to specific tools.

Method 1: Sticker in the Service Book

The simplest way to find the engine code is to check the service book or owner’s manual. Often, a sticker inside the front cover lists essential information, including the engine code. This is the quickest method, but the sticker might be missing or faded in older vehicles.

Method 2: Sticker in the Spare Tire Well

In many Audi S4 models, you can also find a sticker with the engine code located in the spare tire well. Lift the carpet or flooring to access the spare tire, and look for a sticker on the body panel. This location is usually protected from the elements, so the sticker is often in good condition.

Method 3: Using a Diagnostic Scan Tool

A diagnostic scan tool, such as an OBD-II scanner or VCDS (VAG-COM Diagnostic System), can retrieve the engine code directly from the car’s ECU. This is a reliable method, especially for newer models. Simply connect the scanner to the OBD-II port, typically located under the dashboard on the driver’s side, and follow the prompts to access the engine information.

Method 4: Checking the Engine Block (Less Common)

In some cases, the engine code might be stamped or etched directly onto the engine block. However, this can be difficult to locate and might require cleaning or removing some components for better visibility. Consult your car’s service manual for the exact location if you choose this method. You might need information on Audi S4 6202 error code to help diagnose any issues.
