About the Audi Q7
The Q7 was Audi’s first SUV. It arrived for the 2007 model year in the US (production started in Bratislava, Slovakia in November 2005, with European sales beginning as a 2006 model), launching Audi into the full-size luxury SUV segment alongside the Mercedes-Benz GL and BMW X5, and alongside its own corporate siblings, the Volkswagen Touareg and Porsche Cayenne. All three shared the Volkswagen Group PL71 platform in their first generation, which is why an early Q7, Touareg, and Cayenne feel so mechanically related underneath the badges.
| Generation | Years | Chassis code | Platform | Built at |
|---|---|---|---|---|
| 1st | 2005-2015 (NA MY2007-2015) | Typ 4L | PL71 (shared with VW Touareg, Porsche Cayenne) | Bratislava, Slovakia |
| 2nd | 2015-2026 (NA MY2017-present) | Typ 4M | MLB Evo | Bratislava, Slovakia |
The chassis codes 4L and 4M do not appear literally in the VIN; like most VW Group internal codes, they are parts-catalog and enthusiast shorthand. What the VIN does confirm, directly, is the plant and the model year, which is enough to separate a first-generation Q7 from a second-generation one at a glance.
One fact worth knowing up front: every US-market Q7 we decoded, across both generations and fourteen model years, was built at the same factory, Volkswagen Slovakia’s plant in Bratislava. That plant is unusual even by VW Group standards; it is the only automotive plant in the world assembling vehicles for four brands under one roof, running the Q7 down the same lines as the Touareg, Cayenne, Skoda Superb, and VW Passat.
Audi announced a third-generation Q7, internally coded G8 and built on the new Premium Platform Combustion architecture, in summer 2026, with German order books opening that June and deliveries beginning in September 2026. That new generation has not reached the US market yet and no US-spec VINs exist for it, so it is not included in the tables below, which cover the two generations actually sold and titled in the United States.
Audi Q7 WMI codes (positions 1-3)
Every Q7 VIN we decoded, spanning the 2007 launch model year through the current SQ7, and every engine from the base V6 to the SQ7’s twin-turbo V8, begins with the same three characters:
| WMI | Registered to | Vehicle type | Notes |
|---|---|---|---|
| WA1 | Audi AG (parent: Volkswagen AG) | Multipurpose Passenger Vehicle (MPV) | Confirmed on 1st- and 2nd-generation Q7 and SQ7 VINs, 2007 through 2021, all decoded to a Bratislava build |
Audi uses WA1 across its US-market SUV lineup, from the Q5 up through the Q7. The plant itself is encoded separately at position 11, covered below. If a listed Q7 VIN doesn’t start with WA1, run it through the decoder above before trusting the listing.
How to decode an Audi Q7 VIN, position by position
Positions 1-3: World Manufacturer Identifier
See the WMI table above. Every genuine US-market Q7 VIN starts WA1.
Positions 4-8: Vehicle Descriptor Section (VDS)
As with other Audi SUVs, the Q7 does not isolate its engine to one single character. Positions 4 through 8 move together as a block, and the engine and trim are read from the whole block rather than one digit. Here is what we confirmed by decoding real VINs from actual sold vehicles against NHTSA vPIC:
| Generation | Engine / variant | Confirmed VIN prefix (positions 1-8) | Model year decoded |
|---|---|---|---|
| 1st (4L) | 4.2 FSI V8 | WA1EV94L | 2007 |
| 1st (4L) | 3.6 FSI V6 | WA1AY74L | 2007 |
| 1st (4L) | 3.0 TDI V6 diesel | WA1VMBFE | 2010 |
| 2nd (4M) | 3.0T supercharged/turbo V6, Premium | WA1AAAF7 | 2017 |
| 2nd (4M) | 3.0T V6, Premium Plus | WA1LAAF7 | 2017 |
| 2nd (4M) | 2.0T inline-4 | WA1LHAF7 | 2018 |
| 2nd (4M) | 3.0T V6, Prestige | WA1VAAF7 | 2018 |
| 2nd (4M) | SQ7 4.0T twin-turbo V8 | WA1VWAF7 / WA1AWBF7 | 2020-2021 |
Two things fall out of that table. On the first-generation 4L, position 8 reads L on both the gas V8 and gas V6 we decoded, and E on the diesel; the real differentiator is positions 4 through 7, not position 8 alone. On the second-generation 4M, position 8 reads 7 across every engine checked, base four-cylinder through SQ7 V8; again the whole block, not one digit, encodes the powertrain. Don’t try to read the engine off a single character; feed the full VIN into the decoder above and let it match the whole block against Audi’s build data.
One engine you will not find in this table, or in any US NHTSA vPIC record: the 6.0-liter twin-turbo V12 TDI diesel. Audi built it for the first-generation Q7 starting with the 2009 model year, and it remains the only twelve-cylinder diesel engine ever fitted to a passenger vehicle. It made 500 horsepower and 738 lb-ft (1,000 Nm) of torque through a six-speed automatic already near its torque limit, and could push the roughly 5,900-pound SUV to 62 mph in about 5.5 seconds. Audi never sold it in the United States, reportedly over low projected demand against the cost of federalizing such an expensive, low-volume engine. Because it was never imported or titled here, there is no US-spec WA1 VIN carrying it, and NHTSA’s vPIC database, which only covers vehicles certified for the US market, has no record of it. We are not including a VIN example for it here for that reason: doing so would mean guessing at a WMI and VDS block we could not verify, which this page does not do.
Position 9: Check digit
Calculated from the other 16 characters using modulo-11 math. A single mistyped character breaks the math, and any compliant decoder, DMV, or insurer will reject it. Every VIN used to verify this page passed NHTSA’s check-digit validation cleanly.
Position 10: Model year
The 10th character maps to model year on a 30-year cycle, per the ISO 3779 standard used by every VIN built since 1981. The letters I, O, and Q are never used, since they can be misread as 1 and 0. For the Q7’s production span, 2005 through the present:
| Char | Year | Char | Year |
|---|---|---|---|
| 5 | 2005 | H | 2017 |
| 6 | 2006 | J | 2018 |
| 7 | 2007 | K | 2019 |
| 8 | 2008 | L | 2020 |
| 9 | 2009 | M | 2021 |
| A | 2010 | N | 2022 |
| B | 2011 | P | 2023 |
| C | 2012 | R | 2024 |
| D | 2013 | S | 2025 |
| E | 2014 | T | 2026 |
| F | 2015 | ||
| G | 2016 |
We confirmed both ends of the range directly against real VINs: position 10 7 decoded to model year 2007 on the launch-year Q7 VINs above, and M decoded to 2021 on a current-generation SQ7 VIN.
Position 11: Assembly plant
A single character identifying the specific factory. Every Q7 and SQ7 VIN we decoded, first- and second-generation alike, spanning 2007 through 2021, carried D at position 11, and every one resolved to Bratislava, Slovakia. Unlike some Audi models that switched plants between generations, the Q7 has never moved production.
Positions 12-17: Serial number
The production sequence number for that specific vehicle. Combined with the previous 11 characters, this makes every Q7 VIN globally unique, even between two Prestige-trim SQ7s built the same week.
Q7 and SQ7 trim levels by generation
Reconstructed from the VDS block plus the equipment group on Audi’s build sheet. Common North American trims:
- 1st gen (2007-2015): Base/3.6, Premium, Premium Plus, Prestige; S line package; 3.0 TDI diesel from MY2009; 4.2 TDI and V12 TDI offered in Europe only, never sold in the US
- 2nd gen (2017-present): Premium, Premium Plus, Prestige, available with an S line package; 2.0T four-cylinder added as an entry engine in 2017; SQ7 added for MY2020 with a 4.0-liter twin-turbo V8; the Q7 55 TFSI e plug-in hybrid exists in Europe but not in the US
Audi does not build an “RS Q7.” The performance flagship here is the SQ7; Audi’s RS-badged full-size SUV is the related, Q8-based RS Q8.
Where to find the VIN on an Audi Q7
- Lower-left corner of the windshield, visible from outside the car
- Driver’s side door jamb (Audi data sticker with VIN, paint code, and equipment codes)
- Engine bay, stamped on the front bulkhead
- Vehicle title, registration, and the myAudi app
Audi Q7 recalls and safety
Notable NHTSA campaigns pulled directly from NHTSA’s recall database, across the Q7’s run:
- Fuel pump flange crack (MY2007-2012, campaign 16V660, expanded by 18V818): the flange could crack and leak fuel near an ignition source; the remedy replaced the flange and added a protective butyl band.
- Fuel rail leak (MY2016-2018, campaign 19V035): left and right fuel rails on 4M-generation Q7s could leak; dealers replaced both.
- Third-row seat back support (MY2017, campaign 16V641): the third-row seat back could move forward under load in a frontal collision; dealers added a support bracket.
- Steering shaft bolt (MY2017-2019, campaign 20V149): the bolt connecting the steering shaft to the steering gear could loosen, risking a loss of steering control.
- Fuel pump failure (MY2020-2021, campaign 22V516): an internal fuel pump component could break and stall the engine; dealers replaced the pump.
Separately, the Q7’s 3.0-liter TDI V6, built 2009-2016, was one of the Volkswagen Group engines implicated in the 2015 diesel emissions matter; affected owners received a hardware and software fix plus restitution, and the vehicles were later cleared for continued sale.

Frequently asked questions
How do I decode an Audi Q7 VIN?
Type the 17-character VIN from the windshield, door jamb, or title into the decoder above. Results return in seconds: generation, model year, engine, trim, plant of origin, and any open NHTSA recalls. No sign-up required.
What does an Audi Q7 VIN starting with WA1 mean?
WA1 is the WMI Audi AG uses across its US-market SUV lineup. Every Q7 and SQ7 VIN we decoded, first- and second-generation alike, starts WA1. If a listed VIN starts with anything else, treat it as suspect and confirm with the decoder above.
Can I decode a V12 TDI Audi Q7 with this tool?
Not reliably. Audi never sold the 6.0-liter V12 TDI Q7 in the United States, so there is no US-certified WA1 VIN for it in NHTSA’s vPIC database, which only covers vehicles built for the US market. A European or Middle East-market Q7 V12 TDI carries a different, non-US WMI, which a US-focused decoder like this one cannot verify.
How do I tell which generation my Q7 is from the VIN?
There’s no single character that spells out “4L” or “4M.” The fastest shortcut is position 10, the model year: 7 through F (2007-2015) means a first-generation Q7, while H onward (2017-present) means a second-generation Q7 or SQ7. Positions 4 through 8 confirm the exact engine once you know which generation you’re looking at.
Was the Audi Q7 always built in Bratislava?
Yes, for every VIN checked. Production began at Volkswagen Slovakia’s Bratislava plant in November 2005 and has stayed there through both generations sold in the US. That same factory also builds the Touareg, Cayenne, Skoda Superb, and VW Passat on shared lines, the only plant in the world producing four brands under one roof.
Is the Audi Q7 VIN decoder free?
Yes, with no sign-up. A full vehicle history report (accident records, odometer history, prior ownership, salvage status) is available as a paid upgrade if you need it.
Can an Audi Q7 VIN be faked?
The 17 characters can be retyped on a counterfeit plate, but the check digit at position 9 catches most single-character changes through math, and the engine bulkhead stamp is physically tied to the original car. If the windshield and door-jamb VINs match but the bulkhead stamp doesn’t, the car may have been cloned. The guide how to check if a car is stolen by VIN walks through the verification steps.
