Unlock Full VIN ReportWhere Is the VIN Number on an Audi A6?
Every Audi A6 sedan, Avant and allroad carries the same 17 character VIN, also called the chassis number, in several places on the car and on its paperwork. Check that at least two of them match before you rely on it.
On the car
- Bottom of the windshield on the driver side, readable from outside
- Label on the driver door jamb or B pillar
- Vehicle data sticker in the spare wheel well, under the trunk floor
- Stamped into the body in the engine bay, which is where the chassis number lives
On the paperwork
- Title and registration in the US, or the V5C logbook in the UK
- Vehicle data sticker inside the front of the service book
- Insurance documents
- Service invoices and the original sales paperwork
If the VIN on the windshield doesn't match the door label, the paperwork or the body stamping, stop there and find out why before you go any further.
How to Read an Audi A6 VIN
European A6 VINs usually start WAUZZZ, where the three Z characters are filler. US VINs use those positions for engine, body and restraint details instead. On both, positions 7 and 8 tell you the generation and position 10 tells you the model year.
Example European format: WAUZZZ4G0DN012345, a 2013 C7 A6
- Positions 1 to 3: Manufacturer
- WAU identifies Audi as the maker.
- Positions 4 to 8: Model
- Positions 7 and 8 are the model code, like 4G on the example above. On European cars, 4 to 6 are usually ZZZ filler. On US C8 cars you'll see F2 here instead.
- Position 9: Check digit
- Validates the VIN on US cars. On many European cars it doesn't follow the US formula, which is why US decoders often reject them.
- Position 10: Model year
- A single character for the model year. See the list below.
- Position 11: Plant
- The factory that built the car. N is Neckarsulm, home of the A6.
- Positions 12 to 17: Serial number
- The production number that makes this VIN unique.
Audi A6 generation codes in the VIN
| Positions 7 and 8 | Generation | Years |
|---|---|---|
| 4B | A6 C5 sedan, Avant and allroad, plus S6 and RS6 | 1997 to 2005 |
| 4F | A6 C6 sedan, Avant and allroad, plus S6 and RS6 | 2004 to 2011 |
| 4G | A6 C7 sedan, Avant and allroad, plus S6 and RS6 | 2011 to 2018 |
| 4A or F2 | A6 C8 sedan, Avant and allroad, plus S6 and RS6. European VINs show 4A, US VINs show F2. | 2018 to 2025 |
This guide covers the C5, C6, C7 and C8 cars. The newer A6 e tron and the 2025 on A6 are separate models.

Can You Get an Audi A6 Build Sheet or PR Codes From the VIN?
Not from the VIN itself. The 17 characters tell you the model, generation and year, but not the options.
The full build sheet is stored against the VIN in Audi's factory system, so any Audi dealer can pull it with your VIN. If you'd rather do it yourself, the same PR codes are printed on the car.
Spare wheel well Easiest
Lift the trunk floor. The vehicle data sticker lists the VIN, paint code, engine code, gearbox code and every PR code on the car.
Service book
An identical sticker sits inside the front cover. Handy if the one in the trunk is damaged or missing.
Audi dealer
Give the service desk your VIN and ask for the vehicle data printout. It shows the original build and every factory code.
VCDS or OBD11
A scan tool reads coding from the control modules. Good for confirming lighting, suspension or assistance equipment, but it won't give you the full PR list on its own.
Grab the codes from either sticker and paste them into the decoder below to get your full Audi A6 options list.

Which Audi A6 Do I Have?
Positions 7 and 8 of the VIN give you the generation. From there, the engine code and data sticker tell you if you're looking at a standard A6, an allroad, an S6 or an RS6.
A6 C5 (1997 to 2005)
Now a condition and history car. The 2.7T biturbo and the V6 TDI engines need careful checking, and gearbox type matters: manual, Multitronic CVT or Tiptronic.
A6 C6 (2004 to 2011)
Bigger, with MMI and FSI engines. The facelift arrived for 2009. Check the engine code closely, especially on 3.2 FSI and diesel cars.
A6 C7 (2011 to 2018)
Lighter aluminum heavy body, supercharged 3.0 TFSI and strong V6 TDIs. The facelift arrived for 2015. Lighting, audio and assistance options start moving the value.
A6 C8 (2018 to 2025)
Twin touchscreen MMI, virtual cockpit and mild hybrid engines. Spec can matter almost as much as the engine, so read the data sticker before you compare prices.
| Model | What it is | How to confirm it |
|---|---|---|
| A6 | Petrol or diesel sedan or Avant, front wheel drive or quattro | Engine code on the sticker and the absence of S or RS codes |
| A6 S line | Styling and interior pack, same engines as the A6 | S line PR codes on the sticker, not the bumpers or badges |
| A6 allroad | Raised Avant with quattro and air suspension | allroad on the dealer printout and the quattro code 1X1. Cladding can be added later, factory ride height can't. |
| S6 | Performance model, always with quattro | S6 engine code, the quattro code 1X1 and the dealer printout |
| RS6 | Top performance model with a twin turbo engine and quattro | RS6 engine code and the dealer printout. Visual upgrades can't copy the engine. |
S line, Black Edition, Premium Plus or Prestige?
Trim names depend on the market. UK cars are sold as SE, Sport, S line, Black Edition and Vorsprung. US cars are Premium, Premium Plus and Prestige. They don't translate cleanly, and bumpers, wheels, black trim and badges are easy to change after the fact. The VIN alone won't confirm trim. The PR codes on the data sticker, or the dealer printout, will. If a car is priced like a higher spec A6, the codes should prove it.
Audi A6 Engine, Gearbox and Drivetrain: What to Check
The same A6 badge covers a front wheel drive CVT sedan, a quattro diesel Avant and a twin turbo RS6, and the mix changes by market. Confirm the mechanical setup before you judge the spec.
Engines
C5 and C6 cars range from four cylinder petrols through V6 and V8 engines, with 2.5, 2.7 and 3.0 TDI diesels in Europe. C7 cars moved to the 2.0 TFSI, the supercharged 3.0 TFSI and the 3.0 TDI. C8 cars use 2.0 and 3.0 TFSI engines with mild hybrid systems, plus TDIs outside the US.
Gearboxes
Front wheel drive C5, C6 and C7 automatics use the Multitronic CVT. quattro cars use Tiptronic torque converter automatics or S tronic dual clutch boxes depending on engine and year. Most C8 petrol cars use the 7 speed S tronic, while V6 TDIs and the S6 and RS6 use an 8 speed Tiptronic in most markets.
Front wheel drive or quattro
Lower output A6s are often front wheel drive, especially in Europe. quattro is standard on the allroad, S6 and RS6 and common everywhere else. A quattro A6 should show 1X1 on its data sticker.
Why it matters
A front wheel drive Multitronic sedan, a quattro TDI Avant and an RS6 share a badge but not running costs, insurance or value. Engine code, gearbox and drivetrain first, then worry about wheels and trim.
| Setup | What it is | What it means for a buyer |
|---|---|---|
| Manual | 5 or 6 speed | Mostly C5 and C6, and rare on later cars. Simple and cheap to maintain. |
| Multitronic (01J, 0AW) | CVT automatic | Front wheel drive C5, C6 and C7 only. Smooth, but research it hard and look for records of gearbox work. |
| Tiptronic | 5, 6 or 8 speed torque converter | Common on quattro C5 and C6 cars, many C7 V6 cars and the RS6. Smooth and traditional. |
| S tronic DL501 (0B5) | 7 speed dual clutch | Found on many C7 quattro cars including the S6, and on C8 V6 petrol cars. Quick shifts, and it needs its fluid changed on schedule. |
| S tronic DL382 (0CK) | 7 speed dual clutch | The C8 four cylinder gearbox. Servicing still matters. |
| quattro | All wheel drive | Standard on allroad, S6 and RS6. More grip and appeal, with higher running costs to match. |
Audi A6 Common Problems by Engine and Gearbox
Known issues depend on the exact engine, gearbox, body style and generation, which is why confirming them comes first.
| Engine or setup | What to look for | Why it matters |
|---|---|---|
| C5 2.7T biturbo | Turbo wear, coil packs, oil leaks, heat damaged hoses | Expensive to put right, and the engine has to come forward for turbo work. |
| C5 2.5 TDI V6 | Camshaft and follower wear | A well known weak point on early cars. Look for proof the work has been done. |
| C6 3.2 FSI | Timing chain wear and carbon buildup on the intake valves | Chain work on this engine is a big job. Listen for rattle on a cold start. |
| C7 2.0 TFSI | Oil consumption, timing chain tensioner wear | Good engines when looked after. The exact engine code tells you if the car has the updated parts. |
| 3.0 TFSI supercharged | Water pump and thermostat leaks, PCV faults | Common repairs on C7 cars. Check the coolant level and look for crusty residue around the pump. |
| Multitronic CVT | Hesitation, judder, shudder when pulling away | Front wheel drive cars only. Confirm the gearbox and look for evidence of repairs. |
| S tronic DL501 | Mechatronic faults, clutch wear, harsh or slipping shifts | Service history on the gearbox matters. |
| 2.0 and 3.0 TDI | DPF, EGR and other emissions system wear | Short journeys are hard on diesel emissions systems. Common on UK and European cars. |
| Air suspension | Sagging corners overnight, compressor faults, warning lights | Standard on the allroad and optional on others. Park it overnight and check the ride height in the morning. |
| C8 mild hybrid | Electrical faults, 48 volt system warnings, MMI glitches | Mechanically newer, but more electronics to go wrong. Check for software updates and warning lights. |
How to Check Audi A6 Recalls
Recall campaigns differ by market, so check through the channel that covers where the car was sold.
In the US
Run the VIN through the decoder above for NHTSA recall records, or use the NHTSA recall lookup directly.
In the UK
Use the DVSA vehicle recall checker on GOV.UK with the make, model and year, then ask an Audi dealer to run the VIN.
Imported cars
A car sold new in one country may never have had recall work done in the country it's in now. An Audi dealer can check the VIN against every open campaign.
Never assume recall work was done. Ask for proof it was completed, not just booked. Older A6s in particular should be checked for airbag campaigns.
Audi A6 Wheel and Tire Sizes
Wheels are easy to swap, so compare what's on the car with what it left the factory with. Wrong sizes or budget tires change how an A6 rides and handles.
| Wheel size | Common tire size | Typical on |
|---|---|---|
| 17 inch | 225/55 R17 | Entry level cars, Premium and SE |
| 18 inch | 245/45 R18 | Most mid spec cars and many allroads |
| 19 inch | 255/40 R19 | S line, Black Edition, Prestige and S6 |
| 20 inch | 255/35 R20 | S line options and S6 |
| 21 or 22 inch | 275/35 R21 or 285/30 R22 | RS6 and top spec options |
The tire placard on the door jamb shows the sizes approved for that exact car.

Audi A6 VIN Decoder FAQs
Where is the VIN number on an Audi A6?
At the bottom of the windshield on the driver side, on the door jamb label, on the data sticker in the spare wheel well and service book, and stamped into the body in the engine bay. It's also on the title or V5C logbook.
Where is the chassis number on an Audi A6?
The chassis number is the VIN. It's stamped into the body in the engine bay and repeated on the windshield, door jamb and data sticker.
Can I decode a UK or European Audi A6 VIN?
Only partly with most free tools, because they run on US data. You can read the generation and model year yourself using the guide above, then decode the PR codes for the full spec.
What does WAUZZZ4G mean?
WAU is Audi, ZZZ is filler used on European market VINs, and 4G is the model code for the C7 A6. A C5 shows 4B, a C6 shows 4F and a C8 shows 4A in the same spot.
Is my Audi A6 a C6, C7 or C8?
Look at positions 7 and 8 of the VIN. 4F is a C6, 4G is a C7, and 4A or F2 is a C8. Position 10 gives you the model year.
How do I get an Audi A6 build sheet?
Read the PR codes from the data sticker in the spare wheel well or service book and paste them into the decoder above. An Audi dealer can also print the full factory spec from your VIN.
Can the VIN confirm S line, Premium Plus or Prestige?
Not on its own. The VIN confirms the model and year. Trim and packs show up in the PR codes and on the dealer printout.
Can the VIN tell me if my A6 is Multitronic, S tronic or Tiptronic?
Not reliably. US decoders sometimes return a transmission style, but the gearbox code on the data sticker or the dealer printout is the proof.
How do I know if an Audi S6 or RS6 is genuine?
Check the engine code, the quattro code 1X1 on the data sticker and the dealer printout. Bumpers, badges and wheels prove nothing.
Does every Audi A6 have quattro?
No. Many are front wheel drive, especially lower output European cars. quattro is standard on the allroad, S6 and RS6 and common on everything else.
