Decode any Mercedes-Benz MB100 VIN free. Type the 17-character number from your van, minibus, or panel van into the decoder above and pull the chassis series (W631, or the earlier N1000 predecessor), model year, engine family (OM615, OM616, OM617, OM602), body variant, and the exact plant that built it. No sign-up.
This page is the dedicated MB 100 hub. The MB 100 is one of the more misunderstood commercial Mercedes because it wasn’t built in Germany, wasn’t sold in the United States, and lived a second life in Korea under SsangYong. If you own one, are about to buy one, or are trying to source parts, the VIN is where the answers actually live.
About the Mercedes-Benz MB 100
The MB 100 is the light commercial van that Mercedes-Benz España S.A. built at the Vitoria-Gasteiz factory in the Basque Country. It replaced the earlier N1000 series in 1987 and stayed in production at Vitoria until 1996. Two generations exist:
| Series | Years | Chassis code | Built at | Notes |
|---|---|---|---|---|
| N1000 (1st) | 1981 to 1987 | 611 | Vitoria, ES | Pre-facelift, mostly OM615 diesel |
| MB100 (2nd) | 1987 to 1996 | W631 | Vitoria, ES | Introduced Jan 1987 in Mallorca |
| SsangYong Istana | 1995 to 2003 | (KPT VIN) | Pyeongtaek, KR | Licensed rebadge, sold as MB100/MB140 in Australia and Pacific |
Model designations inside the W631 range refer to gross vehicle weight, not displacement. The MB 100 is a 1.0 tonne payload van; the MB130, MB140, MB150, and MB180 step up to heavier ratings on the same chassis. All wore the same body but differed in springs, axle rating, and often engine spec.
The Vitoria plant delivered roughly 200,000 W631s across nine years across panel van, minibus (up to 15 seats), pickup, chassis-cab, and ambulance conversions. In 1999, DaimlerChrysler Australia/Pacific brought the Korean-built variant to Australia as the MB 100D and MB140D (model type 661) using the licensed OM602 2.9L five-cylinder. Australian buyers who own one are technically driving a SsangYong Istana with a Mercedes badge.
Mercedes-Benz MB 100 WMI codes (positions 1 to 3)
The first three characters of the VIN identify the country and manufacturer. On the MB 100 you’ll see two possible WMIs depending on where the specific van was built:
| WMI | Country | Plant | Applies to |
|---|---|---|---|
| VSA | Spain | Mercedes-Benz España, Vitoria | W631 (1987 to 1996) and N1000 late-production |
| KPT | South Korea | SsangYong, Pyeongtaek | Istana / licensed MB100 / MB140 (1995 to 2003) |
| WDB | Germany | Reserved for German-built passenger Mercedes | Should not appear on a real MB100 |
The distinction matters. A Vitoria-built MB 100 uses Mercedes chassis codes and Mercedes engine codes throughout its VDS. A Pyeongtaek-built van uses the same body but the VDS follows SsangYong conventions, and the engine, though a licensed Mercedes design, will read differently in the VIN. If your MB 100 VIN starts with WDB or WDF, treat it as suspect; those are for German-built passenger cars and modern Sprinters, not the Spanish van.
How to decode a Mercedes MB 100 VIN, position by position
The MB 100 uses the ISO 3779 17-character standard from 1987 forward. A small number of very early N1000-era units carry a shorter chassis number and require a separate lookup. For any VIN that is exactly 17 characters, here is what each position means on a W631.
Positions 1 to 3: World Manufacturer Identifier
Almost always VSA for a Vitoria-built MB 100 (and its MB130, MB140, MB150, MB180 siblings). The V flags Spain, S flags Mercedes-Benz, and the third character narrows down vehicle class. A W631 body-on-frame van reads VSA.
Positions 4 to 8: Vehicle Descriptor Section (VDS)
Positions 4 to 6 carry the chassis series. On the MB 100 you’ll typically see:
| Chars 4–6 | Meaning |
|---|---|
| 631 | W631 chassis (all MB100 W631 units) |
| 611 | N1000 predecessor (late Vitoria production) |
| 661 | Australian-market MB100D / MB140D via SsangYong licensing |
Position 7 encodes body style and restraint spec. On a W631 you’ll see distinct values for panel van, minibus, dropside pickup, and chassis-cab. Position 8 is the engine.
The MB 100 engine codes are:
| Char (pos 8) | Engine | Output | Fitment |
|---|---|---|---|
| 0 (615) | OM615 2.0L I4 diesel | 58 PS (43 kW) | Early MB100, MB90 |
| 6 (616) | OM616 2.4L I4 diesel | 72–75 PS (53–55 kW) | Most common MB100 and MB130 |
| 7 (617) | OM617 3.0L I5 turbo diesel | 120–127 hp | AMG-tuned specials, rare |
| 2 (602) | OM602 2.9L I5 diesel | 95 hp | Late Vitoria and Korean-built units |
| 4 (601) | OM601 2.3L I4 diesel | 79 hp | Some MB130 export builds |
| P | 2.3L petrol I4 (M102) | Varies | Post-1996 petrol conversions, rare |
The engine code combined with the chassis code at positions 4 to 6 is what lets a decoder return “1994 MB 100D panel van with OM616” instead of just “Mercedes van.” Two W631s from the same model year can carry very different position-8 characters depending on whether the buyer optioned the base 2.4 diesel or the 3.0 five-cylinder.
Position 9: Check digit
The 9th character validates the other 16. It’s calculated from a fixed weighting table and modulo-11 math. Because the MB 100 was built for European commercial fleets and often re-registered multiple times, the check digit is the fastest way to catch a mistyped chassis number on a title or an insurance quote. Every compliant decoder, the Spanish DGT, and the EU vehicle registry flag any VIN whose position 9 doesn’t match.
Position 10: Model year
The 10th character maps to model year on the standard 30-year cycle. For an MB 100, the useful window looks like this:
| Char | Year | Char | Year |
|---|---|---|---|
| H | 1987 (W631 launch) | N | 1992 |
| J | 1988 | P | 1993 |
| K | 1989 | R | 1994 |
| L | 1990 | S | 1995 |
| M | 1991 | T | 1996 (final Vitoria year) |
For SsangYong-built continuations sold as MB 100D / MB140D in Australia and Pacific markets from 1999 through 2003, position 10 rolls through X (1999) to 3 (2003). The letters I, O, and Q are never used in a VIN, which sometimes trips up MB 100 owners squinting at faded stampings.
Position 11: Assembly plant
A single character identifies the specific factory:
| Char | Plant | Notes |
|---|---|---|
| F | Vitoria-Gasteiz, Spain | The vast majority of MB100 W631 units |
| A | Bremen, Germany | Extremely rare export-prep completions |
| P | Pyeongtaek, South Korea | SsangYong-built Istana / MB100D / MB140D |
If you’re looking at a European MB 100 and position 11 is anything other than F, verify the WMI. A KPT prefix with a Vitoria plant code, or a VSA prefix with a Pyeongtaek plant code, is a data mismatch worth investigating.
Positions 12 to 17: Serial number
The final six characters are the production sequence stamped on the specific van as it rolled off the Vitoria (or Pyeongtaek) line. Combined with the previous 11 characters, this makes every MB 100 VIN globally unique. Two identical-looking panel vans built the same week still differ in these six characters.
MB 100 engine codes explained
Because the MB 100 was built as commercial-fleet equipment across nine years, its engine bay saw more variation than a typical Mercedes passenger car of the era:
- OM615 (2.0L I4 diesel): The base engine on the earliest W631 and the smaller MB90. Same block family as the 1970s W123 240D. Underpowered for a fully loaded panel van but bulletproof.
- OM616 (2.4L I4 diesel): The volume-selling engine. About 72 PS at launch, uprated to 75 PS mid-run. Non-turbo, indirect injection, rated for 500,000+ km when serviced.
- OM617 (3.0L I5 turbo diesel): The engine everyone actually wants. Fitted to a small number of AMG-tuned MB 100 specials. Same block family as the W123 300D Turbo. If you find one in a used MB 100, the position-8 character will be
7. - OM602 (2.9L I5): Naturally aspirated five-cylinder that appeared late in Vitoria production and became the standard powerplant for the Korean-built continuation. In Australia this is the engine in every MB 100D and MB140D.
- OM601 (2.3L I4): Small volume, mostly heavier MB130 export builds.
Petrol conversions exist but weren’t factory-standard until well after 1996 and only in specific export markets.
Body variants of the MB 100
The W631 was sold in more body types than most people realise:
- Panel van (short and long wheelbase)
- Minibus (9-, 12-, and 15-seat configurations)
- Chassis-cab (for coachbuilt ambulances, camper conversions, refrigerated bodies)
- Dropside pickup
- Crew cab pickup
- Factory ambulance and refrigerated van
Position 7 of the VIN, combined with the chassis code at positions 4 to 6, encodes which body left the factory. When the decoder above returns “MB100D panel van long wheelbase,” it’s reading positions 4 to 7 together.
Where to find the VIN on a Mercedes MB 100
The MB 100 has more VIN locations than most modern Mercedes because it was built as a work vehicle and expected to survive collision repair:
- Manufacturer plate on the driver-side B-pillar (the primary sticker)
- Stamped into the chassis rail under the driver seat (lift the carpet or seat base)
- Stamped on the engine block, top rear near the firewall
- Stamped on the front cross-member, visible from underneath
- Vehicle title, registration, insurance paperwork
For a genuine Vitoria-built MB 100, all four physical stampings should match, and all four should match the WMI VSA on paperwork. If the sticker on the B-pillar reads a different VIN from the chassis stamp, the van has been re-shelled or the plate has been swapped. This is more common on MB 100s than on newer Mercedes because so many were converted (camper, ambulance, refrigerated) or restored after fleet use.
Mercedes MB 100 recalls and known issues
The MB 100 predates most modern recall databases and was never sold in the United States, so NHTSA has no record of it. European recall history for the W631 is thin but does include a small campaign on early rear brake proportioning valves and a service action on OM616 injection pumps for 1990 to 1992 units.
To check a specific MB 100:
- Decode the VIN with the tool above to confirm the exact chassis series and build year
- Cross-reference the 17-character VIN with the European Commission’s RAPEX vehicle recall database
- Contact Mercedes-Benz España or a Mercedes commercial vehicle specialist for any open service campaign
The bigger practical issues on used MB 100s tend to be rust in the sills and rear wheel arches, front lower A-pillar corrosion, and injector pump wear on high-mileage OM616 units. None of these are recalls; they are the reason a pre-purchase VIN decode plus a physical inspection matters more on this van than on a modern one.
Frequently asked questions
How do I decode a Mercedes MB 100 VIN?
Type the 17-character VIN from the B-pillar sticker, chassis stamp, or title into the decoder at the top of this page. The result returns the chassis series (W631 or 611), body style, engine family, model year, plant of build (Vitoria or Pyeongtaek), and any recorded service campaigns. No sign-up or credit card.
What does an MB 100 VIN starting with VSA mean?
VSA is the WMI for Mercedes-Benz España in Vitoria-Gasteiz, Spain. Every genuine Vitoria-built MB 100, MB130, MB140, MB150, and MB180 has a VIN starting with VSA. If your MB 100 paperwork shows a different WMI, verify against the physical chassis stamps before assuming the VIN is authentic.
Is the SsangYong Istana the same as an MB 100?
The SsangYong Istana is a licensed rebadge of the MB 100 body shell, built at SsangYong’s Pyeongtaek plant in South Korea from 1995 to 2003. It uses a KPT-prefix VIN, not VSA. In Australia and the Pacific, DaimlerChrysler sold the Korean-built version as the Mercedes MB100D and MB140D (model type 661). Mechanically similar to a late Vitoria unit, but the VIN structure and the engine (OM602 2.9L I5) differ.
What engine is in my MB 100?
Look at position 8 of the VIN. 6 decodes to the OM616 2.4L diesel (the volume seller). 0 decodes to the OM615 2.0L. 2 decodes to the OM602 2.9L five-cylinder. 7 decodes to the OM617 3.0L turbo five (rare AMG special). Cross-reference with the engine block stamp; on the MB100 both should match.
Is the Mercedes MB 100 VIN decoder free?
Yes. VinDecoderPlus decodes every MB100 VIN free with no sign-up. The basic decode covers everything the Vitoria factory stamped into the VIN, including chassis, engine family, and body. A paid vehicle history upgrade is available if you also need ownership records, odometer history, and accident data.
Can an MB 100 VIN be faked?
The 17 characters on the B-pillar sticker can be replaced, but the chassis-rail stamp, the engine block stamp, and the front cross-member stamp are much harder to alter. On a genuine MB100 all four match. Because the van saw fleet, ambulance, camper, and refrigerated use, cloned VINs are more common on this model than on passenger Mercedes. If any of the four physical stampings disagree, treat the paperwork as unreliable and walk. The guide how to check if a car is stolen by VIN covers the verification steps.
