A Mercedes-Benz CLK-Class VIN is 17 characters. Positions 1–3 say who built it and where, 4–8 describe the body and engine, 9 is a check digit, 10 is the model year, 11 is the plant, and 12–17 are the serial number.
How to read a Mercedes-Benz CLK-Class VIN
Here is a real 2009 Mercedes-Benz CLK-Class VIN from our database, split into its parts:
VIN WDBTK72FX9T101140 — decoded free on its own report page.
| Position | Section | What it tells you |
|---|---|---|
| 1–3 | WMI | World Manufacturer Identifier — country, manufacturer and vehicle type. |
| 4–8 | VDS | Vehicle Descriptor Section — body style, engine, restraint system, series. |
| 9 | Check digit | A calculated digit that validates the whole VIN. Wrong digit = wrong VIN. |
| 10 | Model year | One character for the model year. Letters skip I, O, Q, U and Z. |
| 11 | Plant | The assembly plant that built the car. |
| 12–17 | Serial | Sequential production number of this exact vehicle. |
Where Mercedes-Benz CLK-Class VINs say the car was built
The first three characters are the World Manufacturer Identifier. Across 13 Mercedes-Benz CLK-Class VINs we have on file, these are the codes that actually show up — and the plants behind them:
| WMI | Built in | Vehicle type | VINs on file | Share |
|---|---|---|---|---|
| WDB | Germany | Passenger Car | 13 |
Country and vehicle type come from the NHTSA manufacturer registry. Share is measured across VINs decoded on ForCar, not production volume.
Model-year codes for the Mercedes-Benz CLK-Class
Position 10 carries the model year, skipping I, O, Q, U and Z. The alphabet comes round every 30 years, which the Mercedes-Benz CLK-Class has not yet outlived — its 12 years still map one-to-one. All 12 model years of the Mercedes-Benz CLK-Class, 1998 to 2009, with the character each one carries:
| Model year | VIN character (position 10) | Same character as |
|---|---|---|
| 2009 | 9 | — |
| 2008 | 8 | — |
| 2007 | 7 | — |
| 2006 | 6 | — |
| 2005 | 5 | — |
| 2004 | 4 | — |
| 2003 | 3 | — |
| 2002 | 2 | — |
| 2001 | 1 | — |
| 2000 | Y | — |
| 1999 | X | — |
| 1998 | W | — |
When two years share a character, the check digit and serial range tell them apart — that is what the decoder does automatically.
Body and engine characters we see on Mercedes-Benz CLK-Class VINs
Positions 4 through 8 describe the build, and manufacturers assign them themselves — the same letter means different things on different marques. Across 13 VINs the Mercedes-Benz CLK-Class uses 8 different characters in these three slots alone — the ones below, ordered by how much of the Mercedes-Benz fleet each covers:
| Position | Characters seen on real VINs | Variety |
|---|---|---|
| 4 — body | T (69%) · L (31%) | 2 distinct |
| 5 — series | K (69%) · J (31%) | 2 distinct |
| 8 — engine | G (69%) · F (15%) · J (8%) · H (8%) | 4 distinct |
A character that dominates the column usually marks the body style the model was mostly sold in; a spread across several means multiple bodies or engines shared the same platform.
What a decoded Mercedes-Benz CLK-Class VIN gets you
Reading the characters is the easy part — the reason to decode a VIN is what sits behind it. Here is what a decoded VIN opens up:
| Data | For this model | Source |
|---|---|---|
| Recall campaigns | 31 campaigns | NHTSA |
| Fuel economy | 19 mpg combined (avg) | EPA |
| Model years covered | 12 years | ForCar catalog |
Where to find the VIN on a Mercedes-Benz CLK-Class
A Mercedes-Benz CLK-Class VIN normally opens with WDB. Four places on the car carry the full number, and all four must agree — on a Mercedes-Benz CLK-Class, a plate that disagrees is where fraud shows itself first.
| Where | How to see it | Why it matters |
|---|---|---|
| Dashboard, driver side | Through the windshield, bottom corner | Easiest to check before you touch anything |
| Driver door jamb | Open the door, sticker on the pillar | Also lists tyre pressures and build date |
| Under the hood | Firewall or strut tower plate | Survives a windshield replacement |
| Title and insurance | Paper documents | Must match the car — a mismatch means fraud or a swapped panel |

Frequently asked questions
Is this Mercedes-Benz CLK-Class VIN decoder free?
Yes — decoding a Mercedes-Benz CLK-Class VIN costs nothing and needs no account. Beyond the year, plant and build characters you also get what NHTSA holds on the Mercedes-Benz CLK-Class — 31 recall campaigns — at no charge.
How many characters is a Mercedes-Benz CLK-Class VIN?
Seventeen, on every Mercedes-Benz CLK-Class built from 1981 onwards, when the 17-character format became mandatory in the US. The oldest Mercedes-Benz CLK-Class VIN on file here is a 1999, so everything in our Mercedes-Benz data already uses the modern layout.
Why do two Mercedes-Benz CLK-Class model years share the same VIN character?
Position 10 cycles through the alphabet every 30 years, skipping I, O, Q, U and Z. A 1995 and a 2025 car can carry the same letter. The check digit and serial range separate them.
Can a Mercedes-Benz CLK-Class VIN tell me if the car was in an accident?
Not from the characters themselves — they describe how the Mercedes-Benz CLK-Class left the factory, not what happened to it afterwards. Crash and title records sit in separate databases keyed to the same number. Run the number through our VIN check to see what is on the record for it.
Do the body and engine characters mean the same thing on every Mercedes-Benz?
No, and that is the usual mistake — positions 4–8 are assigned per model, not per brand. A letter that means one body on the Mercedes-Benz CLK-Class can mean a different one on another Mercedes-Benz, and something else again on another marque. On Mercedes-Benz CLK-Class VINs the character that dominates position 4 is T — read it against the table above, not against a generic chart.
What if the VIN on the dashboard doesn't match the door jamb?
Treat it as a red flag on any car, and on a Mercedes-Benz CLK-Class check the prefix first: a genuine one opens with WDB, and a plate that starts otherwise did not come off this car. Beyond that, mismatched plates mean either a replaced panel or a tampered identity — ask for documents and verify before any money changes hands.
