Audi VIN Engine Code Finder: Where to Find Your Engine Code Quickly
Ever ordered a replacement part only to find it doesn’t fit because you had the wrong engine code? This happens more often than you’d think. Audi uses specific engine codes to identify exactly which powerplant is under your hood — and knowing where to find yours can save you from costly mistakes.
If you’re short on time, here’s the quick version: Your Audi’s engine code is a combination of letters and numbers that identifies the exact engine variant in your car. It’s printed on the vehicle data sticker (in the spare tire well or service book), on the engine block itself, and on a sticker on the timing belt cover. You can also get it through your VIN from an Audi dealer.
Key Takeaways
- Engine code identifies the exact engine variant — critical for ordering the right parts
- Vehicle data sticker (in spare tire well or service book) lists the engine code
- Engine block stamping location varies by engine type
- Timing belt cover sticker usually displays the engine code
- Audi dealer or erWin portal can provide engine code from your VIN
What Is an Engine Code and Why Does It Matter?
That string of letters on your data sticker — what does it actually tell you?
An Audi engine code is a combination of letters and numbers that identifies the specific engine variant installed in your vehicle. For example, CZRA, CNTC, or DHHA are all different 2.0-liter engine codes with different specifications.
Here’s why this matters: Two Audis with the same engine displacement (say, 2.0 liters) might have completely different parts. One might have a turbocharger, another might be naturally aspirated. One might have different fuel injection, another might have different cylinder heads.
When ordering parts — especially major components like coil springs, brakes, or engine parts — you often need the PR Code (three-character code) from your data sticker, not just the engine displacement. The PR Code tells the parts supplier exactly which variant of a part your car needs.
In rally racing, knowing every component was critical. Audi brought that same precision to their engine code system.
Where to Find Your Audi Engine Code
Method 1: Vehicle Data Sticker (Easiest Way)
The vehicle data sticker is the most reliable place to find your engine code without getting your hands dirty. It contains all the information needed to purchase spare parts.
Location:
- In the spare tire well on the floor of the vehicle
- Under the cover on the right side of the air intake compartment
- On station wagon models, the sticker is under the rear seat
- The duplicate sticker is on the first page of the Service/Maintenance Manual in the owner’s manual
What the sticker shows:
- 1 – Vehicle identification number (VIN)
- 2 – Type designation/production number
- 3 – Vehicle type
- 4 – Engine power/emission standards/gearbox
- 5 – Engine and gearbox code letters (the engine code!)
Method 2: Engine Block Stamping (Physical Check)
The engine code and serial number are stamped directly into the cylinder block. The location varies depending on engine type:
| Engine Type | Location of Engine Number |
|---|---|
| 4-cylinder (1.8L turbo / 2.0L) | Left side of the cylinder block |
| V6 petrol engine | Right inner side of cylinder block, between cylinder head and hydraulic pump |
| 6-cylinder diesel (3.0L TDI) | Left side at the joint between engine and gearbox |
| 8-cylinder diesel (4.0L TDI) | Inside left surface below the intake manifold |
| 12-cylinder petrol (6.0L MPI) | Left side at the joint between engine and gearbox |
Method 3: Timing Belt Cover Sticker
The engine number is also printed on a sticker located on the timing belt cover. This is often easier to spot than the block stamping.
Method 4: Audi Dealer or erWin Portal (From VIN)
If your data sticker is missing or illegible, take your VIN to an Audi dealer. They can provide a complete printout of all codes associated with your car. Audi’s official erWin service portal also provides this information.
If your data sticker is missing, take your VIN to your local Audi and they should be able to provide you with a complete print out of all PR codes associated with your car.
Comparison Table: Where to Find Audi Engine Codes
| Location | Accessibility | Reliability | Best For |
|---|---|---|---|
| Vehicle data sticker | Easy | High | Quick lookup, parts ordering |
| Engine block | Hard | High | Verification, if sticker is missing |
| Timing belt cover | Moderate | High | Quick visual confirmation |
| Audi dealer/erWin | Easy | Very High | Complete build data, if sticker is missing |
How to Use Engine Codes for Parts Ordering
When ordering parts online or from a dealer, you’ll often need to provide your engine code. Here’s a real-world example:
Scenario: You need replacement coil springs. Your VIN won’t tell you which springs you need, but the PR Code (which includes the engine code) will.
Process:
- Locate your vehicle data sticker
- Note the engine and gearbox code letters (section 5 on the sticker)
- When using parts websites, filter by your engine code to find the correct part
- On official parts sites, you’ll often see engine codes listed explicitly (e.g., “2.0 LITER Engine Code CZRA”)
PR Code Decoders: Websites like oemVWshop.com can decode PR Codes and give you their meanings, which is essential when you’re trying to interpret a long list of codes.

Frequently Asked Questions
What is an Audi engine code and why do I need it?
An engine code identifies the exact engine variant in your Audi. You need it to order correct replacement parts, as different engine codes for the same displacement may have different specifications.
Where is the engine code on an Audi VIN?
The VIN contains some engine information (character 5 often indicates engine type), but not the full engine code. For the exact code, check the vehicle data sticker or engine block.
How do I find my Audi engine code without a data sticker?
Check the engine block stamping (locations vary by engine type) or the sticker on the timing belt cover. Alternatively, take your VIN to an Audi dealer for a printout.
What does the vehicle data sticker include?
It includes the VIN, vehicle type, engine power, gearbox type, engine and gearbox code letters, paint code, interior code, and PR Codes for additional equipment.
Is the engine code the same as the VIN?
No. The VIN is a 17-character unique identifier for your vehicle. The engine code is a separate code that identifies the specific engine variant and appears on the data sticker and engine block.
Can I get my engine code from the Audi app?
The MyAudi app sometimes shows standard and optional equipment. For the exact engine code, the data sticker or dealer printout is more reliable.
