Where is the VIN number in Citroen C4 Aircross (2012-2013)?

This guide covers the Citroen C4 Aircross (Aircross, 2012–2013). Important context: the C4 Aircross is not the same as a Citroen C4 hatchback—it’s based on the Mitsubishi ASX/Outlander Sport platform, so some “Citroen C4 VIN location” advice online points to the wrong place.

Chassis Number Locations

1) Engine Bay – Firewall / Bulkhead Stamp

• Where to look: Open the bonnet and locate the firewall/bulkhead (the metal wall separating the engine bay from the cabin). The VIN is stamped directly into the metal, typically high up and slightly off-center (often toward the passenger side on LHD cars), sometimes tucked behind/above the engine near the upper weatherstrip line.
• Access: Expect it to be grimy/greasy and in shadow. Hoses or insulation can partially overhang the stamping. Wipe it down with a rag and use a flashlight to read it cleanly.
• Note: Don’t waste time looking at the strut tower like on a “normal” Citroen C4—Aircross/ASX-style VIN stamping is on the firewall.
• Tip: If the stamping is dirty and hard to read, use ScanVin.app “High Contrast AI Mode” and scan it instead of trying to decipher faint characters by eye.

2) B-Pillar / Door Frame VIN Sticker (Manufacturer Label)

• Where to look: Open the front passenger door (sometimes driver’s door depending on market). Check the B-pillar (center pillar between front and rear doors) near the latch area or lower down near the sill for the VIN sticker/manufacturer label.
• Access: Easy to reach, but stickers can fade, peel, or get scratched, and the glossy surface can reflect your phone flash.
• Note: For RHD markets, the sticker is typically on the opposite side pillar.
• Tip: If glare washes out the print, scan at a slight angle and let ScanVin.app OCR capture the VIN cleanly without you manually typing it.

3) Windshield VIN Plate (Dashboard Corner)

• Where to look: Stand outside the vehicle and look through the windshield at the bottom corner on the driver’s side (LHD) for the VIN tag.
• Access: Fast to check, but reflections are common. Wiper position can also block the view.
• Note: This is useful for a quick match, but it’s not the easiest to scan through glass.
• Tip: If reflections make it unreadable, use ScanVin.app to capture instantly when the characters become visible—this reduces transcription mistakes.

Video Guide

No valid PUBLISH-ready video links (with YouTube IDs) were provided in the inspection data.
If you find a good video showing the Mitsubishi ASX firewall VIN stamp, it usually matches the C4 Aircross layout—but avoid generic “Citroen C4 VIN location” videos (they often show the wrong model).

Common Problems & Troubleshooting

• Firewall stamp is unreadable: It’s usually just road grime/grease. Scrub lightly with a rag and a mild cleaner, then rescan using high contrast.
• Too dark / awkward angle in engine bay: The VIN is stamped high and deep against the bulkhead. Use a flashlight and scan instead of trying to write it down while leaning over the engine.
• Sticker vs stamped VIN mismatch: Pillar stickers can be replaced or damaged. For legal/identity checks, always rely on the stamped chassis number and ensure it matches paperwork.
