How to Tell If an Audi Has Servotronic


1. Open the driver's door and locate the fuse panel on the left side of the dashboard.
2. Insert the flat screwdriver into the small slit on the fuse panel and pry it loose.
3. Look inside the fuse panel, behind the fuse box, for the Servotronic module. It will be marked with a '638' stamp or 'Servotronic' marking. If the module is not there, then your Audi does not have Servotronic.
