About the Mercedes-Benz SLK-Class

The SLK-Class introduced the retractable hardtop concept to the modern sports-car market in 1996. It was produced from 1996 to 2016, and you’ll find it as a Two-seat folding-hardtop roadster. Assembly happened at: Bremen, Germany.

The SLK-Class VIN encodes everything from chassis code and engine family through to factory options, production plant and model year.

A few things worth knowing about the SLK-Class

The original R170 SLK (1996) introduced the modern retractable hardtop to the mass market, with a five-second power-folding metal roof. The 2004 SLK55 AMG was the smallest car AMG had ever fitted with a V8, paving the way for the C63, E63 and SLS AMG variants that followed.

How to decode a Mercedes-Benz SLK-Class VIN

Every Mercedes-Benz VIN built since 1981 follows the ISO 3779 standard. That gives you 17 alphanumeric characters split into three blocks: the World Manufacturer Identifier (positions 1 to 3), the Vehicle Descriptor Section (positions 4 to 9) and the Vehicle Identifier Section (positions 10 to 17). Here’s what each chunk tells you about your SLK-Class.

Positions 1 to 3: World Manufacturer Identifier (WMI)

WDB and WDD both appear.

Positions 4 to 8: Vehicle Descriptor Section (VDS)

R170, R171 and R172 chassis codes are encoded in VDS positions 4 to 8.

Position 9: Check Digit

The check digit comes from a weighted sum of the other 16 characters. Think of it as a self-validating control. If you mistype any single character on your SLK-Class VIN, the check digit won’t match and the VIN is flagged as invalid.

Position 10: Model Year

Position 10 tells you the model year using a rolling alphanumeric scheme. A quick Mercedes-Benz cheat sheet: S = 1995, Y = 2000, 5 = 2005, A = 2010, F = 2015, L = 2020, P = 2023, R = 2024, S = 2025, T = 2026.

Position 11: Assembly Plant

Position 11 is 'F' (Bremen, Germany).

Positions 12 to 17: Production Sequence Number

The final six digits are the unique serial number stamped on your specific SLK-Class as it rolled off the assembly line.

Mercedes-Benz SLK-Class engine codes

Over the years the SLK-Class has been offered with the following engine families: M111 Kompressor, M112 V6, M152 AMG V8, M271 inline-four, M276 V6, M152 AMG V8. Mercedes-Benz engine codes follow a tight naming convention. The letter ‘M‘ denotes a petrol/gasoline engine (think M256, M177, M139), while ‘OM‘ (Oel-Motor) flags a diesel (OM651, OM654, OM656 and so on). Want to know exactly which engine sits under your SLK-Class? Decode the VIN above. VDS positions 4 to 8 will give you the exact engine variant.

Third, stamped into the engine firewall or chassis rail (this is typical for two-seat folding-hardtop roadster bodies). And fourth, printed on the vehicle title, registration and insurance card.
