Where is the VIN number in Audi A6 (C7)?

This guide shows where to find the VIN (chassis number) on the Audi A6 C7 (Typ 4G) produced between 2011–2018, including the easiest sticker location and the more “hidden” stamped chassis spot under the hood.

Chassis Number Locations

1) B-Pillar / Door Jamb Production Label (Sticker)

• Where to look: A black sticker with white text (VIN + weight ratings) on the B-pillar (the post between the front and rear doors), usually on the lower section.
• Access: Easy—open the front door and read/scan the sticker. Minimal glare and great contrast.
• Note: On most LHD A6 C7s it’s commonly on the driver-side B-pillar; the video example is RHD, so it appears on the opposite side.
• Tip: For the fastest, error-free capture, scan the sticker directly with your phone—the clean contrast makes OCR lock on instantly.

2) Engine Bay VIN Stamp (Under Cowl/Seal near Strut Tower/Firewall)

• Where to look: The VIN is stamped into the chassis metal in the engine bay near the strut tower/firewall area (on LHD cars: typically the passenger side).
• Access: Moderate—open the hood, then lift the rubber weather seal and pry up the plastic cowl/cover at the base of the windshield to reveal the stamping underneath. Expect shadows and trapped dirt/leaves.
• Note: The video car is RHD, so the stamping is shown on the vehicle’s left side (passenger side on RHD). Use the same “base-of-windshield cowl” reference point on LHD.
• Tip: Because it’s dark and often grimy under the trim, use ScanVin’s flashlight + high-contrast scan to pull the characters out without guessing.

3) Lower Windshield VIN Plate (Dashboard Corner)

• Where to look: At the bottom corner of the windshield, on top of the dashboard—VIN visible through the glass (market-dependent).
• Access: Easy to reach, but reflections/glare can make it hard to read, and wiper position/dust can block it.
• Note: Availability varies by region; if you don’t see it, use the B-pillar label or the engine-bay stamping.
• Tip: To beat windshield glare and avoid mistyping, capture the VIN instantly with the VIN scanner instead of transcribing it by hand.

4) Trunk / Boot Floor Build Data Sticker (Spare Wheel Well Area)

• Where to look: Under the trunk floor mat, typically near the spare tire well (build data sticker format used across VAG).
• Access: Harder—may require clearing luggage, lifting the floor, and the sticker may be torn/faded/dirty.
• Note: Best used as a backup if the door sticker is missing or if you’re cross-checking details.
• Tip: If the sticker is worn or partially unreadable, use the phone scanner to grab what’s still visible so you don’t misread similar characters (B/8, O/0, S/5).

5) MMI / Infotainment VIN Display (Software Menu)

• Where to look: In the MMI menus (commonly: Car Settings → Servicing & Checks → VIN).
• Access: Requires vehicle power/ignition on; not helpful if the battery is dead.
• Note: Useful for verification, but always match it to a physical VIN location for identity checks.
• Tip: If you’re comparing VINs from different sources, scan the physical label with ScanVin to avoid menu/typing mistakes.

Common Problems & Troubleshooting

• Engine bay stamp is “invisible”: It’s often buried under the rubber seal and plastic cowl lip and can be covered with grime/leaves—wipe it and use a flashlight before you assume it’s missing.
• Windshield VIN glare: Sunlight reflections on glass can hide characters—change your viewing angle or shade the area with your body/hand.
• Sticker vs. stamped VIN: Door/boot stickers can be replaced—when buying, always cross-check the B-pillar label against the stamped chassis VIN.
