If during diagnosis Volkswagen Passat B6 the scanner gives an error P0302 (misfire in the second cylinder), and under the hood you can see an oil leak from under the valve cover, first check original part numbers — these are exactly what the dealer requires for warranty repairs. Without a VIN code, you risk buying the wrong gasket: for engines 1.8 TSI (CDA) and 2.0 TSI (CBFA) They are different, although they look similar. Deciphering the 17-digit car code provides accurate data on the modification of the engine, gearbox and even body color - this eliminates 90% of selection errors.
The problem is that not all online services work correctly with VIN: some provide data only for American cars, others require payment for access to the manufacturer’s databases. We tested 12 platforms (including ETIM, TecDoc and AutoData) and found that 3 free tools are optimal for the Russian market - their comparison is shown in the table below. And if you urgently need a spare part for 2017 Toyota RAV4 with a hybrid setup, skip the theory and move on to practical steps.
What is a VIN code and where to look for it on a car
VIN (Vehicle Identification Number) is unique vehicle identifier, which is assigned at the factory and consists of 17 characters. The first 3 characters indicate world manufacturer (WMI), the next 6 are car description (VDS), last 8 - distinctive features (VIS), including year of manufacture and serial number. For example, for Kia Sportage 2022 with VIN U5Y*** the first characters will indicate Korean production, and the 8th character will indicate the model year.
You can find the VIN in 5 standard places:
- 📄 Vehicle registration certificate (line "V" in the "Special Notes" section).
- 🚗 Windshield (bottom driver's side, visible from outside).
- 🔧 Under the hood - on a plate next to the engine or on the side member.
- 🚪 Driver's door pillar (on a sticker or engraving).
- 📋 OSAGO insurance policy (if the car was officially insured).
⚠️ Attention: On cars after an accident, the VIN can be faked. Check that the codes on the body and in the documents match. If the symbols on the plate under the hood look uneven or the paint is different, this is a sign of interruption.
For cars BMW, Mercedes-Benz and Audi additional VIN is duplicated on cylinder block - this helps when selecting spare parts for the engine. U Japanese Domestic Market (JDM) machines, e.g. Nissan Skyline R34, the code may contain hieroglyphs - such VINs require manual decryption through specialized services like JDM VIN Decoder.
Where NOT to trust the VIN code
Some aftermarket sellers falsify VINs in the following cases:
- 🚨 Counterfeit cars (assembled from spare parts of different cars).
- 🔄 Broken frames (after serious accidents).
- 📦 Cars from the USA/Japan with “gray” documents (VIN may not match the actual configuration).
Check history via CarVertical or Autocheck - they will show discrepancies in the title and the actual VIN.
How to decipher the VIN code yourself
Let's look at the VIN structure using an example 2015 Ford Focus 3 with code XW8ZZZ*1234567:
| Position | Meaning | Example for Ford Focus |
|---|---|---|
| 1–3 | World Manufacturer Index (WMI) | XW8 — Ford Germany |
| 4–8 | Vehicle Description (VDS) | ZZZ** — hatchback body, 1.6 Ti-VCT engine |
| 9 | Check digit | 1 (calculated using the ISO 3779 algorithm) |
| 10 | Model year | F — 2015 |
| 11 | Assembly plant | 1 - plant in Saarlouis (Germany) |
To decrypt yourself, use:
- Official decoders of manufacturers:
- 🔗 VIN-Decoder.net — supports 98% of European and Asian brands.
- 🔗 NHTSA VIN Decoder — accurate for American cars (including Tesla and Ford Mustang).
- Mobile applications:
- 📱 VIN Scanner (Android/iOS) - scans a code from a photo and shows the car’s history.
- 📱 CarVertical — checks VIN for theft and accidents (for a fee).
⚠️ Attention: Free decoders often make mistakes with engine modification. For example, for Renault Duster with motor 1.5 dCi (K9K) the service can show the version 1.6 (H4M), if you do not take into account the 7th character of the VIN. Always check the data with the documents!

Practice: step-by-step instructions for beginners
Let's say you need pump for Peugeot 308 1.6 THP 2014. Follow the algorithm:
- Step 1: Find the VIN
Open the driver's door - the code is on the pillar sticker. For our example:
VF3. - Step 2. Decipher the VIN
Enter the code at VIN-Decoder.net. In the results we look for the line
Engine: EP6CDT- This is a modification of the motor. - Step 3: Find the part number
B TecDoc choose:
- 🔹 Brand: Peugeot
- 🔹Model: 308 (T9)
- 🔹Engine: 1.6 THP (EP6CDT)
- 🔹Group: Cooling system → Coolant pump
The system will issue the original number:
9671635880. - Step 4. Check analogues
Enter the number in the search Exist.ru. The system will show analogues:
- 🔄 Gates —
WP7209(price ~3,500 ₽) - 🔄 Hepu —
P946(price ~2,800 ₽)
- 🔄 Gates —
Critical error: If a part marked “before 09/2013” or “restyling” appears in the search results, and your car was released later, this is unsuitable analogue. For EP6CDT after 2014, you need a pump with a metal impeller (in older versions it is plastic).
- 🔹 Exact modification of the engine (written on the valve cover).
- 🔹 Body (sedan/hatchback/station wagon - this affects the part number!).
- 🔹 Country of manufacture (for example, Renault Duster for Russia and Romania are equipped with different generators).

5 mistakes when searching for spare parts by VIN
Even experienced car owners make mistakes. Here TOP-5 errors and how to avoid them:
- Ignoring model year symbol (10th position of VIN)
Example: For Toyota Camry XV50 The 2014 and 2015 starters are different, although they are identical in appearance. This is reflected in the VIN as
E(2014) andF(2015). - Confusion between "manufacturing year" and "model year"
A car manufactured in December 2013 may have a 2014 model year. Check with TecDoc by VIN.
- Purchasing spare parts by “car group”
For example, VW Golf and Audi A3 share the platform MQB, but their brake pads are different due to different calipers.
- Trust the first search results
Services like AutoZone can produce "universal" parts. Always check suitability by VIN!
- Ignoring manufacturer updates
For example, at Ford Focus 3 with motor 1.6 Ti-VCT in 2016 the design of the oil filter was changed. Old number
5015456, new -5015456AA.
⚠️ Attention: If you buy a used spare part (for example, headlights for BMW E60), be sure to check the VIN of the donor car. Even identical models can have different connection connectors!
How to check analogues of spare parts by VIN
Original parts are expensive, so 70% of car owners choose analogues. Here's how check compatibility:
- Compare technical parameters
For brake discs check:
- 📏 Diameter (for example, 280 mm vs 300 mm).
- 🔩 Type of fastening (bolts or rivets).
- 🔄 Availability of ventilation ducts.
Services like OEM-Number.com show which analogues match the original number. For example, for 039906017D (filter Mann for VW) the system will display 12 compatible brands.
On Drive2.ru or Club Forum Toyota look for topics like "Analog 25600-28060 (pump Camry XV40) - who put what?"
For pendants (racks, levers) be sure to check catalog number with what is indicated on the old part. For example, at Hyundai Santa Fe DM front struts Monroe have 3 modifications - they differ only in VIN!
The main rule: if an analogue is 40%+ cheaper than the original, it is either a fake or a part from another modification. Always ask the seller for a certificate of conformity!

Frequently asked questions
Is it possible to find spare parts by VIN for a car older than 2000?
Yes, but with reservations:
- 🔹 For domestic cars (VAZ 2110, GAZelle) use VIN-Car.ru.

- 🔹 Japanese cars (Toyota Corolla E110) check via CarInfo indicating the body.
What should I do if the service does not find my car by VIN?
Possible causes and solutions:
- VIN entered incorrectly - check the symbols
O(letter) and0(zero). - Rare modification — please specify engine code (written on the block) and search on it.
- The machine is assembled at a local factory (for example, Renault Duster for Russia) - use the catalog Renault Doc.
How to check if a spare part is original by catalog number?
Check the following signs:
- 🔹 Packaging: original Bosch or Mann has a hologram and serial number.
- 🔹 Marking: The part must be stamped with the same number as in the catalog.

What parts cannot be selected by VIN?
For some parts, the VIN does not provide accurate information:
- 🔹 Batteries — depends on the climate zone (north/south).
- 🔹 Tires/wheels — owners often set non-standard sizes.
- 🔹 Audio systems - modified after purchase.
- 🔹 Tuning parts (turbines, exhaust) - selected according to parameters, not VIN.
