Improving the manufactured products is a continuous process of any flow production. At the same time, in the automotive industry, except for cases of major design changes of models coming off the assembly line, the results of the modification process are not covered in the vehicle operating manual. However, the manufacturer draws up numbered lists of manufactured spare parts, due to which the information encoded in the identification numbers of the car is of particular importance when purchasing the latter. When ordering the required spare part, try to provide the seller with as much information about your car as possible. Be sure to provide the model name, year of manufacture, as well as the body/chassis and powertrain numbers. The nameplate with the vehicle identification number (VIN) is located to the right of the front passenger seat - a special valve is provided in the carpet (see illustration 1).
Note: On some models, the VIN is stamped on a plate attached to the instrument panel.
1. The VIN plate is located on the floor panel in the passenger footwell - bend back the valve cut into the carpet and remove the cover
The VIN is also duplicated on the manufacturer's plate, fixed in the opening of the front passenger door on the central pillar (see illustration 2), on some models the nameplate is fixed in the engine compartment, next to the right shock absorber strut. In addition to the identification number, the plate also contains some other data (see illustration 3).

VIN Decoding
Example:
| WOL | O | Z | C | F | 35 | 5 | 2 | 123 456 |
| 1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 | 9 |
- 1. Manufacturer code: WOL - Adam Opel AG.
- 2. Specialized version: O - does not belong to the number of special vehicles.
- 3. GM code: Z - Vectra-C/Signum.
- 4. Model range: C - Vectra-C/
- 5. GM code of the vehicle configuration
- 6. Body type: 69 - 4-door Sedan, 68 - GTS, 48 - Signum, 35 - Station wagon
3. Contents of the nameplate
- 1 Manufacturing company
- 2 License Permit Number
- 3 Vehicle Identification Number (VIN)
- 4 Permissible gross vehicle weight
- 5 Permissible gross trailer weight
- 6 Maximum permissible load on the front axle of the vehicle
- 7 Maximum permissible load on the rear axle of the vehicle
- 8 Vehicle-specific/country-specific data
4. Location of the engine identification number
7. Year of model release: Y - 2000, 1 - 2001, 2 - 2002, 3 - 2003 and so on until 9 - 2009, A - 2010, IN - 2011 etc.
8. Manufacturer's code: 1 - Russelsheim, 2 - Bochum.
9. Serial number. The engine designation and number are stamped on the left side of the cylinder block (see illustration 4). The table below provides a detailed breakdown of the information encoded in the engine designation.
Decoding engine designation
Example:
| Z | 18 | X | E | - | - |
| Z | 19 | - | D | T | N |
| 1 | 2 | 3 | 4 | 5 | 5 |
1. Exhaust toxicity standard: Y - compliance with EURO-3 standard, Z - compliance with EURO-4 standard.
2. Working volume (displacement): 18 - 1.8 l, 20 - 2.0 l, etc.
3. Compression ratio: L - 8.5-9.0; N - 9.09.5; S - 9.5-10.0; X - 10.0-11.5; Y > 11.5.
Note: For a diesel engine, the "Y" designation is not significant (all engines have a higher compression ratio) and therefore is not indicated.
4. Fuel: E - gasoline, D - diesel fuel.
5. Features (modification): N - highly boosted, L - low-boost; T - turbocharging.
Note: The letters "H" and "L" are added to the designation of base engines whose performance is improved. For example, the Z19DTH engine (150 hp) is a modification of the Z19DT engine (120 hp).
