Where is the VIN number in Citroen C4 (III [2017-2017])?

For 2017-era “C4” listings, many vehicles are actually C4 Cactus-spec (as shown in the verified video). The best VIN check points are in the engine bay.

Chassis Number Locations

1) Engine Bay Chassis VIN Stamp (inner wing / rain channel)

• Where to look: Open the hood and go to the right side of the vehicle. Locate the upper metal rail/rain channel on the inner fender, right beside the bonnet hinge and near the strut tower. The VIN is stamped/engraved into the painted metal.
• Access: Usually easy to reach, but this channel often holds dust, grit, and grime—scrub or wipe it before trying to read or scan.
• Note: This placement is consistent regardless of LHD/RHD—just keep orientation correct: it’s on the vehicle’s right side.
• Tip: If the stamp is dirty or low-contrast, use ScanVin.app “High Contrast AI Mode” after wiping the area—this helps pull faint characters off painted metal.

2) Manufacturer VIN Label / Sticker (engine bay inner wing/strut tower)

• Where to look: In the same right-side engine bay area, look just below/near the stamped VIN on the inner wing/strut tower section. It’s a tamper-style sticker that also lists weights and other data (often paint code too).
• Access: Very quick visual check, but stickers can peel, fade, or heat-damage over time.
• Note: Treat this as a supporting VIN source—the stamped chassis VIN is the one you rely on for identity checks.
• Tip: If the label is glossy or reflecting light, use ScanVin.app to capture it instantly without transcription errors (move the phone slightly to kill glare).

3) Engine Block Number Stamp (backup check)

• Where to look: On the front of the engine block, stamped onto a machined flat near hose connections (coolant hose area on the example).
• Access: Typically hard: dark, cramped, and often corroded/greasy, with hoses obscuring the view. You may need a flashlight and a rag.
• Note: This is best used as an additional cross-check, not your primary VIN source.
• Tip: Because it’s awkward to reach and easy to misread, scan it with ScanVin.app to avoid writing it down in an uncomfortable position—use High Contrast AI Mode if the stamping is oxidized.

4) Under-hood cowl “VIN window” (rare/variant-dependent)

• Where to look: With the hood open, check the cowl area (plastic trim at the base of the windshield). Some variants have a viewing cutout/window that lets you see a VIN stamped on the bulkhead/firewall area.
• Access: You’ll be working under the hood, and the plastic window area can be scratched or dirty.
• Note: This location is variant-dependent and not the first place I’d check on a 2017 C4/Cactus—use it only if you can’t find the right-side engine bay stamp.
• Tip: If it’s shadowy under the cowl, use ScanVin.app with Flashlight + OCR to pull the characters without squinting.

Common Problems & Troubleshooting

• Stamped VIN is “missing”: It’s usually just packed with dirt in the rain channel—spray cleaner, wipe, then re-check from a different angle.
• Sticker is unreadable: Heat and age can cause peeling/fading—use the stamped chassis VIN as your primary identifier.
• Important: A VIN sticker/label alone isn’t proof of identity. For registration/inspection and anti-tamper checks, the stamped chassis number is the legally meaningful one in most jurisdictions.
