“Allroad” is not one car. It is a raised-suspension, rugged-wagon treatment Audi has applied to two separate model lines since 1999: the full-size A6 allroad quattro, built off the A6 Avant, and the compact A4 allroad, built off the A4 Avant. Both wear the same plastic body cladding and run standard quattro all-wheel drive, but they are different platforms, different engines, and in the US market, different and sometimes non-overlapping sales windows. Below: which generations of each line actually reached America, WMI and plant codes verified against real production VINs decoded through NHTSA, a position-by-position guide, and where Audi stamps the VIN.

The two Audi allroad model lines

Audi’s allroad concept started in 1999 as a single model: a lifted, air-sprung A6 Avant with cladding and a low-range-style Torsen center differential setting. It only became a “family” in 2013, when Audi brought a second, smaller allroad based on the A4 to the US. The two lines have never been sold simultaneously as fresh, current-generation vehicles for more than a few overlapping years, and one of them, the original A6 allroad, actually disappeared from US showrooms for a fourteen-year stretch.

Model line	Generation	Years (global)	Sold in US?	US model years
A6 allroad quattro	C5 (Typ 4B)	1999-2005	Yes	2001-2005
A6 allroad quattro	C6 (Typ 4F)	2006-2011	No	Europe/rest-of-world only
A6 allroad quattro	C7 (Typ 4G)	2012-2018	No	Europe/rest-of-world only
A6 allroad	C8 (Typ 4K)	2019-2026	Yes	2020-2026
A6 allroad	C9	2026-present (Europe)	Confirmed for 2027	Not yet on sale in US as of this writing
A4 allroad	B8/B8.5 (Typ 8K)	2009-2016	Yes	2013-2016
A4 allroad	B9 (Typ 8W)	2016-2025	Yes	2017-2025

We confirmed the “Sold in US?” column two ways: cross-referencing press and enthusiast-forum history, then independently querying NHTSA’s own vPIC model database year by year. For model years 2006 through 2019, Audi’s US model list in NHTSA’s system shows “A6” every year but never “allroad” or “A6 allroad” until 2020. The C6 and C7 A6 allroad were real cars, sold in large numbers in Germany, the UK, and elsewhere, but Audi of America never brought either one in. The nameplate went dark here after the last 2005 C5s sold, and did not return until the smaller A4 allroad arrived for 2013, seven years before the A6 allroad itself came back for 2020 on the C8 platform.

The C9-generation A6 allroad, revealed for European sale in 2026, has been confirmed by Audi for a 2027 US arrival, replacing the outgoing C8. As of this writing the C8 remains the newest A6 allroad you can buy new in an American dealership.

Both lines ride on the same core hardware as their non-allroad siblings, so a lot of what applies to a standard A4 or A6 VIN applies here too. See our Audi A4 VIN decoder and Audi A6 VIN decoder for the full generation, engine, and plant breakdowns of the sedan and Avant versions those allroads are based on. This page focuses on what is different about the allroad variant specifically.

A6 allroad quattro: the original

The C5 A6 allroad launched for 1999 in Europe and 2001 in the US, built around a 2.7T twin-turbo V6 and, from 2003, a 4.2L V8, paired to a self-leveling air suspension that could raise ride height roughly 1.5 to 2.5 inches over a standard A6 Avant at the touch of a dash button. Audi ended US sales after 2005 and did not offer a US A6 allroad again until the C8-based car arrived for 2020, running a 335-hp 3.0L turbocharged V6. The C6 and C7 in between were real, Europe-market-only cars; a US buyer today only encounters one if it was privately imported.

A4 allroad: the compact one

The A4 allroad debuted in Europe for 2009 on the B8 Avant and came to the US for 2013, running the same 2.0T TFSI four-cylinder as the standard A4 sedan, with a taller stance, roughly 1.5 inches of extra ground clearance, and standard quattro. Audi carried it through the B9 redesign for 2017 and kept selling it every year through 2025, the final model year for the A4 nameplate as Audi shifts gas-powered compact models to the A5 name. Unlike the A6 allroad, the A4 version has had a continuous, unbroken US sales run since it arrived.

How to read an allroad VIN: position by position

Both allroad lines use the standard 17-character ISO 3779 VIN, the same format as every other modern Audi.

Positions 1-3: World Manufacturer Identifier (WMI)

We decoded real production VINs from both lines through NHTSA’s vPIC system to confirm these WMIs:

WMI	Country	Model	Plant confirmed
WA1	Germany	C5 allroad quattro (2001-2005)	Neckarsulm
WA1	Germany	A4 allroad, both B8 and B9 (2013-2025)	Ingolstadt
WAU	Germany	A6 allroad, C8 (2020-2026)	Neckarsulm

Every allroad ever sold in the US, of either model line, has come out of Germany; there is no US, Mexican, or other overseas assembly for either nameplate. A VIN that doesn’t start with WA1 or WAU on an allroad claiming US origin is worth a second look.

Positions 4-8: Vehicle Descriptor Section (VDS)

This block carries body, restraint, and engine data, and it is where the two model lines diverge sharply since they don’t share body architecture. On real decoded examples, a 2003 C5 allroad 2.7T reads WA1YD64B63N095722 (VDS block YD64B), a 2013 A4 allroad reads WA1UFAFLXDA129848 (VDS block UFAFL), a 2017 A4 allroad reads WA17NAF47HA062785 (VDS block 7NAF4), and a 2022 A6 allroad reads WAU72BF24NN018456 (VDS block 72BF2). The A4 allroad’s VDS pattern is close to but not identical to the standard A4 sedan’s; our Audi A4 VIN decoder page documents the sedan-specific VDS strings for comparison, including the WAU WMI sedans and Avants carry versus the allroad’s WA1.

Engines confirmed by generation: the C5 allroad ran a 2.7T twin-turbo V6 (250 hp) standard, adding a 4.2L V8 option from 2003; the C8 A6 allroad runs a 335-hp 3.0L turbocharged V6 across its US run; the A4 allroad, both B8 and B9, has run a 2.0T TFSI four-cylinder the entire time, matching the contemporary standard A4 sedan’s base engine. Europe additionally sold TDI diesel allroads on every generation of both lines; none of those diesel allroads have been sold new in the US.

Position 9: Check digit

Calculated from the other 16 characters using fixed weighting and modulo-11 math, this single character catches typos. Every VIN referenced on this page decoded clean; a single mistyped character anywhere breaks the math, and any compliant decoder, DMV, or insurer will reject it.

Position 10: Model year

The 10th character maps to model year on a repeating 30-year cycle shared industry-wide. Scoped to the years relevant for an allroad built since 1999:

Char	Year	Char	Year	Char	Year
X	1999	7	2007	F	2015
Y	2000	8	2008	G	2016
1	2001	9	2009	H	2017
2	2002	A	2010	J	2018
3	2003	B	2011	K	2019
4	2004	C	2012	L	2020
5	2005	D	2013	M	2021
6	2006	E	2014	N	2022
				P	2023
				R	2024
				S	2025
				T	2026

The letters I, O, and Q are never used, since they’re easily confused with 1 and 0. Because the cycle repeats every 30 years, a “1” on an allroad only ever means 2001 given the nameplate’s history; there’s no ambiguity the way there can be on a longer-running model, since no allroad existed before 1999.

Position 11: Assembly plant

Char	Plant	Confirmed on
N	Neckarsulm, Germany	C5 A6 allroad quattro (2001-2005); C8 A6 allroad (2020-2026)
A	Ingolstadt, Germany	A4 allroad, both B8 and B9 (2013-2025)

Both US-sold A6 allroad generations trace back to Neckarsulm, the same plant that builds the standard A6 sedan and Avant. The A4 allroad instead comes out of Ingolstadt, matching the A4 Avant and S4, not the standard A4 sedan (which, per our A4 decoder page, moved to Neckarsulm starting with the B8).

Positions 12-17: Serial number

The final six characters are the production sequence stamped on your specific car as it left the line, making the full 17-character string unique to that one vehicle.

Where to find the VIN

• 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)
• Stamped on the engine bay firewall/bulkhead
• Vehicle title, registration, and (for European-market cars) the Certificate of Conformity

The windshield and door jamb are fastest to check on a lot. The firewall stamp, physically tied to the body shell, is the one to check if you suspect the other labels were swapped, which matters more on an allroad than most Audis given how many C6 and C7 A6 allroads have been privately imported into the US outside normal compliance channels over the years.

Check recalls and safety information

For any allroad actually sold new in the US, plug the VIN into the decoder above, then cross-reference it with NHTSA’s recall database or Audi’s own recall lookup. Both the A4 allroad and the C8 A6 allroad have been swept into some of the same broad Audi/VW Group campaigns as their sedan siblings, including Takata airbag inflator recalls affecting various model years and the electric coolant pump fire-risk campaign (17V-002) that touched 2013-2016 four-cylinder Audis including the B8 A4 allroad.

Recall coverage gets murkier for anything Audi never officially sold here. A C6 or C7 A6 allroad, or any European-market diesel variant of either line, was never submitted to NHTSA for US compliance, so it will not return a clean VIN-based recall history even if it is legally titled and registered under a 25-year-rule import. That’s a real gap, not a decoding error: NHTSA’s databases only cover vehicles Audi certified for the US market, and a blank recall result on a gray-market allroad does not mean “no open recalls.” If you’re looking at an imported C6 or C7, check with a specialist Audi importer or independent European parts/service network instead.

Recall repairs, where they apply, are free regardless of vehicle age, mileage, or ownership history.

Frequently asked questions

What is the difference between the A4 allroad and the A6 allroad?

They’re different cars built on different platforms. The A4 allroad is the compact wagon, based on the A4 Avant, sold in the US continuously since 2013. The A6 allroad is the full-size wagon, based on the A6 Avant, sold in the US from 2001-2005 and again from 2020 onward, with a long gap in between when Audi didn’t offer any A6 allroad in America at all. Both share the raised air suspension and cladding concept, but they don’t share an engine lineup, a plant, or (in the case of the A4 allroad) even the same WMI as their non-allroad sibling.

Was the Audi A6 allroad sold in the US the whole time?

No. Only the original C5 generation (2001-2005) and the current C8 generation (2020-2026) were sold new in the US. The C6 (2006-2011) and C7 (2012-2018) A6 allroad generations were sold in Europe and other markets but never officially imported and sold new by Audi of America. We confirmed this against NHTSA’s own year-by-year US model listings, which show no “allroad” or “A6 allroad” entry for Audi between 2006 and 2019.

How do I decode an Audi allroad VIN?

Type the 17-character VIN from the windshield, door jamb, or title into the decoder above. Results return in seconds: model line (A4 allroad or A6 allroad), generation, model year, engine, plant, and open NHTSA recalls where applicable. No sign-up required.

What does an allroad VIN starting with WA1 mean?

WA1 is the WMI Audi has used on both the original C5 A6 allroad quattro and the entire A4 allroad line. It does not by itself tell you which model line you’re looking at; you need the VDS block at positions 4-8 plus the model year at position 10 to tell a 2003 A6 allroad apart from a 2013 A4 allroad, since both can start WA1.

Can I decode a European-market A6 allroad that was never sold in the US?

Only partially. A C6 or C7 A6 allroad, or a European TDI diesel variant of either line, will decode the WMI, check digit, and model year correctly since those follow the same global ISO 3779 standard, but won’t return a US-specific recall history or full trim breakdown the way an officially imported car does. For genuinely pre-standard chassis numbers, our classic car VIN decoder covers the pre-1981 case; a Europe-only C6 or C7 is a modern 17-character VIN, just one with thinner US data behind it.

Is the Audi allroad VIN decoder really free?

Yes, with no sign-up, covering everything the factory stamped into the VIN. A full vehicle history report, covering accidents, odometer readings, and prior ownership, is an optional paid upgrade; see our guide on what a VIN decode covers versus a vehicle history report if you’re deciding which one you need.

Can an Audi allroad VIN be faked?

The 17 characters can be retyped on a counterfeit plate, but the check digit catches most single-character changes through math, and the firewall stamp is physically tied to the original car. If the windshield and door-jamb VINs match but the firewall stamp doesn’t, treat the car as suspect, particularly on a privately imported C6 or C7 A6 allroad where normal US title-history checks are less reliable. Our guide on how to check if a car is stolen by VIN covers next steps.
