Little wonder in the fact that while using the car, the vehicle needs maintenance from time to time. In such a situation, the only correct solution would be to seek help from real masters. True, and at the same time, not a single driver is insured against running into not the most respectable repairmen.
1. Cleaning the air flow sensor

There is an air flow sensor in the power unit of the car, which helps to prepare the fuel-air mixture.. Quite often, when problems arise with the engine, caring craftsmen offer services to clean this sensor. They say that harmful and dangerous deposits pollute it, thereby impairing the operation of the entire unit.
In most cases, this is a swindle. Problems with the air flow sensor can only appear if a very large foreign body gets into the mechanism. In all other cases, there is no need to clean it.
2. Flushing the injector

Real problems with injectors can only be detected after proper diagnostics. In most other cases, when the driver is asked to flush the injector, they try to cheat him. Experts recommend checking and cleaning the injectors only after passing 60-70 thousand kilometers since the last maintenance. Real masters use special equipment and chemistry for such cleaning.
3. Refueling the air conditioner

If the car has an air conditioner, then the driver may start at each MOT to offer to fill the system with fresh phereon. Station workers often cite that this will improve the performance of the air conditioner. In reality, car manufacturers recommend refueling the air conditioner no more than once every two years. It should also be remembered that, like working with any other auto mechanisms, the air conditioner requires testing on special equipment.
4. Antibacterial treatment

Antibacterial treatment of the ventilation system is really worth doing periodically. But in most cases, the "masters" offering such a service are limited to the use of the most trivial, non-specialized chemistry for cleaning and disinfection. This approach has nothing to do with the planned complex of sanitary measures.
5. Anti-corrosion treatment

Finally, there is one more service that should be ordered directly, and not as a "nice addition". It is important to understand that the quality of such processing largely depends on those reagents and mastics that the masters will use when processing the bottom and thresholds. One of those cases when it is definitely not worth saving on chemistry.
