Where is the VIN number in SEAT Leon (Leon III [2013-2019])?

This guide covers where to find the VIN (chassis number) on the SEAT Leon (Leon III [2013-2019]), including the quickest stamping to check and the common secondary locations used for identification.

Chassis Number Locations

1) Engine Bay – Chassis Stamping (Left Strut Tower / Inner Wing)

• Where to look: Open the hood and locate the left suspension strut tower (inner wing). The VIN is stamped into the painted metal on the top/side of the tower area, right next to the coolant expansion tank cap.
• Access: Low difficulty. It’s high up and easy to reach, but it can be obscured by dirt/grime—wipe it clean before trying to read it.
• Note: “Left” means vehicle-left when sitting in the car (direction of travel). On some markets the “passenger side” wording can flip (LHD vs RHD), so rely on left strut tower rather than “driver/passenger”.
• Tip: If the stamping is dusty or low-contrast, wipe it and then use ScanVin.app’s VIN scanner with high-contrast OCR to pick up faint characters without guessing.

2) VIN Plate/Etching – Windshield Viewing Window (Lower Dashboard Corner)

• Where to look: Check the bottom corner of the windshield on the passenger-side dashboard area, where the VIN is visible through a small viewing window from outside the car.
• Access: Can be tricky due to glare/reflections on the glass; sometimes you need to change your angle or shade the area.
• Note: Best viewed from outside the vehicle, looking down through the glass at the dash.
• Tip: If reflections make it hard to read, capture it instantly with your phone using ScanVin.app to avoid transcription mistakes.

3) Vehicle Data Sticker / Production Label (Engine Bay or B-Pillar Door Jamb)

• Where to look: Look for a black or silver data sticker either:
  • in the engine bay (often near the strut tower area), or
  • on the B-pillar door jamb (open the front door and check the pillar/door shut area).
• Access: Usually easy to see, but on older vehicles the label can be peeled, faded, or missing.
• Note: This sticker is helpful for confirmation, but the stamped VIN is typically the most authoritative physical identifier.
• Tip: If the print is faded, scan the sticker with ScanVin.app so OCR can read what your eyes can’t.

Common Problems & Troubleshooting

• Stamped VIN covered in grime: Degrease/wipe the strut tower area, then re-check the stamping under good light.
• Windshield VIN unreadable due to glare: Move the car into shade, change viewing angle, or block sunlight with your hand/card.
• Sticker not valid proof (or missing): Data stickers can be replaced or removed—always cross-check against the stamped VIN and the vehicle documents.
