Purchase of spare parts (BMW 7 Series E38)

An important role in repair work is played by the use of high-quality spare parts and consumables designed specifically for your car.

In general, spare parts can be divided into two large groups:

Original spare parts

These spare parts are distributed through official representatives of car manufacturers, always have original packaging and appropriate markings. At the same time, the quality of the part is guaranteed by the car manufacturers themselves. The warehouses of official representatives of the manufacturing company usually have all spare parts for a car of this brand in stock. If any part is missing, it can be delivered from the central warehouse in the shortest possible time.

Non-original spare parts

The definition says nothing about the quality of the parts. It only means that they are not sold in the original packaging of the car manufacturer and are not distributed through the official representatives of the company. The backbone of this group is made up of well-known manufacturers of spare parts, supplying parts to the assembly lines of sometimes several car factories at once. Due to the high capacity of their production, such companies also supply spare parts for sale on the open market. Such parts have the packaging and marking of the spare part manufacturer and are in no way inferior in quality to original spare parts at a significantly lower cost (the difference in price can be up to 50%). True, the range is usually a little more modest due to the fact that they try to produce only the most popular, most in-demand parts for open sale. Many large Western spare parts dealers use their own packaging, purchasing a large assortment of non-original parts in large quantities directly from manufacturers and selling them under their own trademark. Non-genuine parts are typically distributed through independent auto accessory stores, auto repair shops and service stations (STOs).



Particular attention should be paid to the quality of the spare parts purchased. Try to avoid buying very cheap parts (compared to original and non-original parts produced by famous companies), because they often do not meet quality and safety standards. If installing a second-rate decorative molding can only negatively affect the appearance of the car, then using low-quality brake pads/oil filter poses a threat to road safety and can cause serious damage to the engine. At the same time, the cost of restoration repairs sometimes exceeds the amount saved by buying a cheap part many times over. This means that you should try to use the services of official representatives of the car manufacturer (original parts), or reputable suppliers of non-original spare parts.

There is also the possibility of purchasing refurbished parts, whereby the old, failed element is usually given in exchange for a refurbished one. This approach is most productive when replacing such complex, expensive components as powertrain units, generator, starter, etc. The said service is provided by both official representatives of the car manufacturer and independent suppliers of spare parts and allows to significantly reduce the cost of car repair. At the same time, the company offering a refurbished unit usually gives almost the same guarantee for it as for a new one.

Identification of spare parts

As mentioned above, car manufacturers, being typical representatives of serial production, strive to constantly improve their products, constantly introducing certain changes and additions to the design of the models produced. It may happen that within one series and one version of the car, some units and assemblies will differ slightly from each other, and a spare part intended for equipping cars of one, for example, earlier year of production will not fit others, released later. In view of the above, when purchasing spare parts, it is very important to provide the seller with the most complete information about your vehicle.



In addition to the standard set of data, including year of manufacture, body type, body version, chassis number, engine number, etc., the seller may be interested in the following information:

• Gearbox type;
• Power supply system type;
• Is there any additional equipment installed on the vehicle? (for example, an additional heater, a more powerful generator, air conditioner, etc.);
• Does the model come with a catalytic converter?;
• Place of installation of the purchased part.

If for any reason the documents reflecting the listed information are missing, it makes sense to first consult with specialists from the representative office of the vehicle manufacturer.

Sometimes, when buying a particular spare part, it is useful to take the old part that needs to be replaced with you for comparison.
