Decode Your VIN
Enter your vehicle's VIN code to discover all technical specifications. The VIN consists of 17 alphanumeric characters.
Decode any Mercedes-Benz ML VIN free. Type the 17-character number from your ML320, ML350, ML500, ML63 AMG, or any other ML variant into the decoder above and pull the chassis series, model year, engine, drivetrain, factory options, plant, and open NHTSA recalls. No sign-up.
This page focuses on decoding the ML trim badge and identifying which specific variant of the M-Class model line you have. For chassis-level history across the three M-Class generations, see our M-Class VIN decoder page. Both pages decode the same VIN using different lenses.
How ML trim badges map to your VIN
Every M-Class was sold with an ML prefix on the trim name. The number after ML indicates the nominal engine displacement (ML320 = 3.2L, ML350 = 3.5L, ML500 = 5.0L), the ML55 and ML63 badges denote AMG variants (5.4L and 6.2L V8), and suffixes like CDI (common-rail diesel), BlueTEC (SCR diesel), and Hybrid identify the drivetrain family.
Here’s how the common ML trims map to what your VIN actually encodes:
| Trim badge | Engine | Chassis (VDS pos 4 to 6) | Engine code (pos 8) | Years |
|---|---|---|---|---|
| ML320 | 3.2L V6 (petrol M112 or diesel OM642) | 163 or 164 | 3 or 8 | 1997 to 2011 |
| ML350 | 3.5L V6 M272 or M276 | 163, 164, 166 | 4 or 6 | 2003 to 2015 |
| ML350 BlueTEC | 3.0L V6 OM642 diesel | 164 or 166 | 8 | 2007 to 2015 |
| ML450 Hybrid | 3.5L V6 M272 + electric | 164 | H | 2010 to 2011 |
| ML500 / ML550 | 5.0L or 5.5L V8 M113 / M278 | 163, 164, 166 | 9 or A | 1998 to 2015 |
| ML55 AMG | 5.4L V8 M113 AMG | 163 | S | 2000 to 2003 |
| ML63 AMG | 6.2L V8 M156 AMG | 164 | 7 | 2007 to 2011 |
| ML250 BlueTEC | 2.1L I4 OM651 diesel | 166 | 8 | 2012 to 2015 (US spec) |
Two ML350s from different years can carry different position-8 characters depending on which engine generation the factory installed. A 2007 ML350 is an M272 V6 (position 8 = 4); a 2013 ML350 is an M276 V6 (position 8 = 6). The decoder above handles the disambiguation automatically.
Mercedes ML WMI codes
| WMI | Country | Plant | Applies to |
|---|---|---|---|
| 4JG | USA | Tuscaloosa, AL (MBUSI) | Every ML since 1997 |
Every genuine ML carries a 4JG WMI. Because the M-Class has been built exclusively at Mercedes’ Tuscaloosa, Alabama plant from 1997 through 2015, an ML VIN with a German or Chinese WMI is not factory-original.
Position-by-position decode for an ML VIN
Positions 1 to 3: WMI
4JG on every ML.
Positions 4 to 6: Chassis series
| Chars 4 to 6 | M-Class generation |
|---|---|
| 163 | W163 first-gen ML (1997 to 2005) |
| 164 | W164 second-gen ML (2005 to 2011) |
| 166 | W166 third-gen ML (2011 to 2015, renamed GLE from 2016) |
Position 8: Engine
Cross-reference the engine table above. Position 8 combined with position 4 to 6 tells you what’s actually under the hood, regardless of what the ML badge on the tailgate says.
Position 10: Model year
Standard ISO 30-year cycle. See the M-Class VIN decoder page for the full year chart. The relevant window for M-Class runs from V (1997) to F (2015).
Position 11: Plant
Always A or B for Tuscaloosa on a genuine ML.
Identifying an ML AMG variant from the VIN
The two AMG-badged ML variants (ML55 AMG on W163, ML63 AMG on W164) can be verified from the VIN in two ways:
- Position 8 will read
S(ML55 AMG with M113 5.4L V8) or7(ML63 AMG with M156 6.2L V8) - The Datacard on the driver-side B-pillar will show the specific AMG package code and factory options
A non-AMG ML with an AMG body kit will carry a standard engine code at position 8. If the VIN says one thing but the badges say another, the VIN is authoritative for the factory build spec.
Where to find the VIN on your ML
- Lower-left corner of the windshield
- Driver-side B-pillar Datacard sticker
- Stamped on the strut tower under the hood
- Stamped into the passenger-side floorpan under the front carpet
- Stamped on the engine block, top rear near the firewall
- Vehicle title, registration, insurance card
Mercedes ML recalls and known issues by trim
Recall history depends on the specific chassis and engine. Common patterns worth watching before you buy:
- ML350 (W164 2006 to 2011): M272 balance-shaft wear, well documented
- ML320 CDI / ML350 BlueTEC: OM642 oil cooler seal leaks, glow plug module failures
- ML500 (W164 2005 to 2007): M113 chain guide wear on high-mileage units
- ML55 AMG (W163): M113 valve stem seal wear, ABC hydraulic pump wear
- ML63 AMG (W164): M156 cylinder head bolt corrosion (extended Mercedes campaign)
- All W164 and W166 units: Airmatic strut leaks on higher trims, Takata airbag inflator recall
To check a specific ML:
- Decode the VIN with the tool above to confirm the exact chassis series and model year
- Cross-reference the 17-character VIN with the Mercedes-Benz USA recall lookup and the NHTSA recall database
- Contact your nearest Mercedes-Benz authorised service centre for any open campaign repair
Frequently asked questions
How do I decode a Mercedes ML VIN?
Type the 17-character VIN from the windshield, B-pillar sticker, or title into the decoder at the top of this page. Results include the exact trim, generation (W163, W164, or W166), model year, engine, drivetrain, and plant. No sign-up.
Is the ML the same as the M-Class?
Yes. Mercedes marketed the model line as the M-Class and badged individual trims with an ML prefix (ML320, ML350, ML500). Owners and used-car listings use ML and M-Class interchangeably. In the VIN, positions 4 to 6 identify the chassis (W163 through W166) and position 8 identifies the engine, regardless of the trim name displayed.
What is the difference between ML350 and ML350 BlueTEC?
The ML350 (petrol) uses either the M272 V6 (2006 to 2011) or M276 V6 (2012 to 2015) depending on year. The ML350 BlueTEC uses the OM642 3.0L V6 diesel with SCR (BlueTEC) emissions system. Position 8 differs: 4 or 6 for the petrol V6, 8 for the OM642 diesel. Both trims are sold under the same ML350 nameplate but they’re mechanically different vehicles.
What year did the ML become the GLE?
Mid-year 2015. Mercedes facelifted the W166 for 2016 and renamed the entire model line from M-Class (ML350, ML550) to GLE (GLE 350, GLE 550). The chassis code stayed 166 in the VIN. If your vehicle is a 2016 or newer, use our GLE-Class VIN decoder page.
Is the Mercedes ML VIN decoder free?
Yes. VinDecoderPlus decodes every ML VIN free of charge with no sign-up. A full vehicle history report is available as an optional paid upgrade.
Can an ML VIN be faked?
The B-pillar Datacard sticker can be replaced, but the strut-tower, floorpan, and engine block stamps are physically tied to the car. Given the value of ML55 and ML63 AMG units on the collector market, cloned VINs are a documented risk. The guide how to check if a car is stolen by VIN walks through the verification steps.
