Where is the front motor number of an Audi located?
3 Answers
The front motor number of an Audi is located on the inclined surface of the engine block at the connection point between the engine rear end and the transmission. Below is some relevant information about the 2021 Audi A3 Sportback 35TFSI Luxury Elegance model: Powertrain: Equipped with a 1.4L turbocharged 4-cylinder DJS engine, paired with a 7-speed dry dual-clutch transmission. Body dimensions: Length, width, and height are 4343mm, 1815mm, and 1458mm respectively. The wheelbase is 2630mm. Chassis: The drivetrain is front-engine front-wheel drive, with a front suspension of MacPherson independent suspension and a rear suspension of multi-link independent suspension.
As an experienced Audi owner, I just helped a fellow car enthusiast locate this last week. Open the engine hood, and you'll usually find the stamped serial number on the housing of the front motor (that cylindrical component). Some models have a silver label attached to the side of the motor, but its position might be blocked by piping. I recommend first cleaning off surface dust, then using a strong flashlight to trace along the top edge of the motor to find the serial number. For hybrid models, it might be hidden behind the inner fender liner of the left front wheel – you'll need to lift the chassis for clear visibility. If you still can't find it, check the vehicle conformity certificate, which prints the complete motor registration number.
Over the years working on auto repairs, I've become quite familiar with Audi's front motor codes. For conventional fuel-powered vehicles, the motor number is typically cast on the metal housing of the motor. You'll need to bend down and look upwards from the lower right side of the front end, roughly behind the coolant reservoir. It's more complicated with new energy vehicles—the front motor code might be stamped near the high-voltage wiring harness interface, requiring removal of the black protective cover. A word of caution: always disconnect the negative terminal of the battery before searching for the code, especially with electric models, as working with live circuits is extremely hazardous. If you can't find the code, don't force it open—it's likely the factory label has fallen off. In such cases, reading the OBD data directly is a more reliable approach.
