Quick response
Quick Answer: The most reliable VIN location for the Mercedes-Benz Klasa S is the front right fender apron under the hood (visible through a small rectangular window in the plastic trim). It’s typically located above the right headlight area—easy to access and scan. Expert tip: if the stamping looks faint, wipe the area and scan instead of trying to read it by eye.
Where is the VIN number in Mercedes-Benz Klasa S (W223/V223/Z223)?
This guide covers the VIN (chassis number) locations for the Mercedes-Benz Klasa S (W223/V223/Z223) produced between 2015–2015.
Chassis Number Locations
Engine bay: front right fender apron (VIN window in trim) 
- Where to look: Open the hood. On the front right side, find the plastic trim panel running along the edge above the headlight. Look for a small rectangular cutout/window in that trim—Mercedes leaves this opening so you can see the VIN. The VIN is stamped into the metal chassis under the window, near the coolant expansion tank and directly above the right headlight unit.
- Access: Very low difficulty. No trim removal needed; just good light.
- Note: The footage shows a RHD car, but write your search in vehicle “right side” terms. On LHD cars, that’s typically the passenger side.
- Tip: If the characters look washed out or dusty, wipe the stamping and scan it directly with your phone using High Contrast AI Mode to avoid misreading similar characters (8/B, 5/S).
Driver’s door jamb: B-pillar VIN label 
- Where to look: Open the driver’s door and inspect the B-pillar (the post between the front and rear doors). Look for a black VIN sticker/label with the VIN plus weight and paint information.
- Access: Low difficulty. No tools; just open the door and aim the camera straight at the label.
- Note: This is a common Mercedes location and is usually the easiest barcode-style scan point when the under-hood stamping is dirty.
- Tip: If small text is hard to read, use the free VIN reader to capture the full string cleanly without manual typing errors.
Cabin floor: under-seat/crossmember stamping (lift carpet flap) 
- Where to look: Move the front seat all the way back. In the front footwell area, locate a pre-cut carpet flap on the vertical crossmember under/near the front of the seat. Lift the flap to reveal the VIN stamped into the metal.
- Access: Moderate difficulty. Poor lighting; carpet flap can be stiff. You may need to pry the flap up carefully with a trim tool or fingernail.
- Note: The video shows RHD and demonstrates this on the right side. For LHD vehicles, check the front footwell floor (commonly on the passenger side for LHD vehicles, but check the driver side footwell if not found).
- Tip: This spot is usually dark—turn on your light and capture it with your phone using the app’s Flashlight + OCR so you don’t have to contort and write it down.
Engine block number (rear left, above transmission area)
- Where to look: This is the engine number, not the easy “consumer” VIN check. It’s stamped on a flat machined surface on the rear left side of the engine block, near the transmission bell housing.
- Access: Extreme difficulty. Typically requires a lift and removal of the underbody splash shield/skid plate.
- Note: This is for workshop verification when ownership/identity is in doubt, not for routine VIN decoding.
- Tip: If you’re checking identity during a purchase inspection, scan the easy VIN locations first and only go underneath if needed—scan the visible VIN with your phone to avoid mistakes while working in an awkward position.

Common Problems & Troubleshooting
- Carpet flap won’t lift / can’t see the stamping: Slide the seat fully back, pry the edge of the flap gently, and use a flashlight—this area is naturally shadowed.
- Under-hood stamping looks faint: Dust and reflections can hide characters; wipe the metal clean and change your viewing angle before scanning.
- Sticker vs. stamped VIN mismatch: Door-jamb stickers can be replaced—when verifying a car, always confirm the stamped chassis VIN matches the label.
