It is necessary to understand what consumable parts or materials are (or "consumables", as many motorists call them). These are elements that can, and sometimes even need to be replaced during the operation of the car or during the next maintenance. That is why consumables are not subject to repair and restoration - they are replaced with new ones, some according to regulations, some as needed. Consumables include all seals, drive belts, gaskets, brake pads, seals, silent blocks, etc.
Now let's look at the concepts of "original" and "non-original" parts. Further, the entire description is given in the context of what we mean by consumables. Original means manufactured at the factory that manufactured your car and, as a matter of course, has a quality certificate, for which the manufacturer is responsible. However, it is worth clarifying that automobile companies have long switched to a subcontracting scheme, that is, they do not manufacture themselves, but transfer the entire process into the hands of another company with specialized production. This company makes the same part, only puts the customer's logo on some, and its own on others. The part that has the customer's logo or name is called original, and the one with the manufacturer's name is non-original. In fact, the same part, but with a different cost. One of the most striking examples is the Lemferder company, which manufactures steering and suspension parts. However, it is necessary to make a reservation about counterfeits. Which may have the name of the car manufacturer and the name of the subcontractor, but with a manufacturing quality that is much lower than average or lower.
The numbers of the original and non-original spare parts may differ, so you need to be careful when choosing them. Many service stations advise using only original spare parts, since in case of unforeseen situations, you can always contact the car manufacturer whose stamp is on the part with the problem. That is why, and also due to the fact that there are a great many manufacturers of non-original spare parts and each of them can assign their own unique numbers to spare parts, the following pages provide information on original consumables.
How do I use the material described on the following pages? Very simple. It usually starts with a chapter on Car Maintenance and operation, which almost always includes a section on routine maintenance work on the car. In this section, you will learn what specific part needs to be replaced according to the vehicle's mileage, such as a fuel filter. Having decided on the name of the part, open the ZV chapter, look for the desired spare part with its catalog number. Write down this number and go to the store or to the Internet.
