Table of Contents
If you are an Audi owner, buyer, or enthusiast, you have likely encountered two important documents: the window sticker and the build sheet. While both provide valuable information about your vehicle, they serve different purposes and have distinct types of data.
Understanding the differences between these two documents can help you verify factory options, authenticate a vehicle’s history, and make informed purchasing decisions.
Let's break down exactly what sets a window sticker apart from a build sheet—and why both matter for Audi owners.
What is a Window Sticker?
A window sticker, formally known as the Monroney label, is the federally mandated label affixed to the window of a new vehicle at the time of sale. It is designed to provide transparency to consumers by displaying information about the vehicle’s pricing, specifications, and fuel economy.
Characteristics
The window sticker and build sheet may look similar; however, they serve different purposes. A window sticker is designed for buyers, showing pricing, features, and official details at the time of sale. In contrast, a build sheet focuses on how the vehicle was assembled at the factory, listing production codes and internal specifications rather than consumer-friendly information.
Legal Requirement
The window sticker is mandated by the Automobile Information Disclosure Act of 1958. This federal law requires that all new vehicles sold in the United States display a label showing the manufacturer’s suggested retail price (MSRP), standard equipment, and optional features with their costs.
Consumer-Facing Document
The window sticker is intended for buyers and dealers. It summarizes the vehicle’s key selling points in an easy-to-read format, helping consumers compare vehicles and understand what they are paying for.
Information Included
MSRP: Base price, optional equipment costs, and destination charge.- Standard Features: Equipment included with the base trim level.
- Optional Equipment: Factory-installed packages and individual options with pricing.
- Fuel Economy: EPA-estimated city, highway, and combined MPG.
- Safety Ratings: Crash test ratings and safety features.
- VIN: The 17-digit Vehicle Identification Number.
- QR Code / Barcode: For digital verification at dealerships.
Primary Purpose
The window sticker serves as a consumer protection tool, ensuring buyers know exactly what they are purchasing and at what cost before signing on the dotted line.
What is a Build Sheet?
A build sheet, also known as a factory build sheet, vehicle specification sheet, or production broadcast sheet. It is created during the manufacturing process and follows the vehicle down the assembly line.
Characteristics
Internal Factory Document
The build sheet is not intended for consumers. It is used by factory workers, quality control teams, and assembly line managers to ensure each vehicle is built to the exact specifications of the customer order.
Comprehensive Component List
Unlike the window sticker, which summarizes key features, the build sheet provides an exhaustive list of every part and component used in the vehicle, including:
- Engine code (e.g., EA888, CATA)
- Transmission code (e.g., DL501, 0B5)
- Paint code (e.g., LY9F for Suzuka Gray, LZ5Y for Nogaro Blue)
- Interior trim code (e.g., QE for Black Leather)
- Suspension components
- Electrical modules and control units
- Every bolt, clip, and fastener used in assembly
Multiple Formats
Build sheets may appear in different forms:
- Paper sheet: Historically, a physical sheet of paper that moved down the assembly line with the vehicle.
- Digital record: Modern vehicles have built-in data stored electronically in manufacturer databases.
- Sticker in spare tire well: Many Audis include a small sticker in the spare tire well or service booklet showing key option codes.
Primary Purpose
The build sheet serves as the master blueprint for manufacturing, ensuring that each vehicle is assembled correctly according to the customer’s order. It is also used by dealership service departments and parts specialists to identify the correct replacement components.

When to Use Each Document
Both the window sticker and the build sheet have almost the same details, but they serve different purposes. Knowing when to use the window sticker and build sheet helps you get the exact information to avoid confusion.
Window Sticker is Best For
If you plan to purchase a used car, be sure to get the window sticker copy to check what features the vehicle has:
Verifying Original MSRP and Pricing
If you need to know what a vehicle cost when it was new—including the base price, optional equipment costs, and destination charge—the window sticker is the definitive source. This information is useful for:
- Calculating depreciation
- Determining fair market value
- Negotiating a used car purchase
Confirming Factory Packages and Options
The window sticker clearly lists every factory-installed package (e.g., Prestige Package, S line Sport Package) and individual options (e.g., Bang & Olufsen sound system, adaptive air suspension) in plain English. This makes it easy to verify trim level and equipment without needing to decode option codes.
Fuel Economy and Safety Information
If you need the official EPA fuel economy ratings or safety ratings for a specific vehicle, the window sticker provides these at a glance.
Resale and Trade-In Documentation
Providing a window sticker to potential buyers or dealers adds transparency and credibility, often helping to justify a higher asking price or trade-in value.
Build Sheet is Best For
Build sheets are best used when you need detailed factory information. They provide exact component data and option codes. That is why a build sheet is essential for accurate parts matching, repairs, and technical verification.
Ordering Replacement Parts
When ordering parts from an Audi dealership or online supplier, the build sheet—specifically the three-digit option codes (known as PR codes or option codes)—ensures you receive the correct component. For example:
- The same Audi A4 may have three different brake caliper options depending on the build sheet codes.
- Suspension components vary based on whether the vehicle has standard suspension, sport suspension, or adaptive air suspension.
Confirming Exact Specifications
If you need to know the paint code for a touch-up pen, the interior trim code for replacement upholstery, or the engine code for performance modifications, the build sheet provides these details. The window sticker does not include this level of specificity.
Restoration and Collector Verification
For classic Audi restorations or collector vehicles, the build sheet is a critical document that proves the vehicle was built to a specific configuration. It helps answer questions like:
- Was this Audi originally equipped with the optional sport seats?
- Did it come from the factory with the quattro all-wheel drive system?
- What is the original paint color?
Service and Repair
Audi service technicians often refer to the build sheet (or digital equivalent) to:
- Identify the correct software version for control modules.
- Verify recall eligibility.
- Determine if a specific component is original equipment or aftermarket.
Understanding Audi Option Codes (PR Codes)
A few differences between a window sticker and a build sheet are the presence of option codes. While the window sticker lists options in plain English, the build sheet uses a standardized system of three-digit PR codes (also called option codes or M-code).
What Are PR Codes?
An Audi PR code (short for Primärausstattung, meaning original equipment) is a three-character alphanumeric code used by the Volkswagen Group to identify factory-installed components, including brakes, suspension, engine, and transmission.
These codes are typically found on a sticker in the service book or inside the trunk, and they help ensure you get the correct replacement parts.
Common Audi PR Codes
PR Code | Description |
9VS | Bang & Olufsen Sound System |
1X1 | Quattro All-Wheel Drive |
GH2 | Rear Differential (Sport Differential on S/RS models) |
2MC | Adaptive Air Suspension |
PC8 | S line Sport Package (exterior) |
4L2 | Rearview Camera |
7K3 | Tire Pressure Monitoring System (TPMS) |
6FJ | Exterior Mirrors – Heated, Power Folding |
3FE | Panoramic Sunroof |
QE | Black Leather Interior |
How to Find Your Audi’s PR Codes
PR codes can be found in several locations:
- Spare Tire Well: Many Audis have a large sticker in the spare tire well listing all PR codes.
- Service Booklet: The original service booklet often includes a sticker with option codes.
- Digital Lookup: Services like Auwi window sticker can provide build data, though PR codes are typically found on the physical build sheet or dealer records.

Common Misconceptions
It’s easy to confuse a window sticker with a build sheet since both show vehicle details. However, they serve different purposes and are used in completely different ways.
The window sticker and build sheet are the same thing
Fact: They are completely different documents. The window sticker is a consumer-facing summary focused on pricing and major options. The build sheet is an internal factory document that lists every component used to assemble the vehicle, down to individual bolts and wiring harnesses.
The build sheet shows the MSRP
Fact: Build sheets do not include pricing information. They are technical documents used for assembly, parts ordering, and specifications—not for pricing or sales. If you need the original MSRP, the window sticker is the correct document.
You don’t need the build sheet if you have the window sticker
Fact: While the window sticker is sufficient for most buyers, the build sheet is essential for:
- Ordering correct replacement parts.
- Restoration projects where the exact original specifications matter.
- Performance modifications where engine and transmission codes are required.
- Confirming paint codes for touch-up or repainting.
Build sheets are only for classic cars
Fact: Every Audi—new and old—has a build sheet (or digital equivalent). Modern Audis store build data electronically, but the information is still accessible through dealer systems or physical stickers in the spare tire well and service booklet.
The window sticker is legally required; the build sheet isn’t
Fact: This is true. The window sticker is mandated by federal law for new vehicle sales. The build sheet is an internal factory document with no legal requirement, though it is a valuable resource for owners and technicians.
