The pads worn out-a light bulb on the dashboard, a low oil level-an image of a red watering can appears on the dashboard, something with a motor-a frightening check engine flashes before my eyes. But even in the most heaped up machine, faults can not be ruled out, which the owner learns only during the next maintenance or, much worse, after an accident. RIA Novosti found out about what breakdowns will not tell any on-board computer and how to recognize them.
Sounds and Knocks
Some of the breakdowns are typical only for used cars, others are possible even for those that recently left the car showroom. They are united by one: they are revealed only by organoleptic diagnostics, that is, with the help of hands, ears, eyes and vestibular apparatus.
Electronic sensors have not yet reached the control of mechanical assemblies, body parts, interior and exterior. "
If in a moving machine on the potholes in front or behind comes a metal screen, this may indicate the wear of the stabilizer bars of the lateral stability (the so-called "bones") or that the replacement of the suspension arms is required. If the sound is only from the front - you need to check the steering rack. Alas, but no sensors will report this. To make sure of the reality of the problem, it is recommended to remove all things from the car to the last candy wrapper, paying special attention to the door pockets and trunk, and to make a test trip. It happens that foreign sounds are produced, for example, by a badly fixed spare tire or a penknife in the glove box.
"Crunch when turning the wheels, most likely, means that the hinge of equal angular velocities (SHRUS) came out of the system, the rumble from the wheels is that the hub or hub bearings must be replaced," says Dmitry Parbukov, head coach of the Audi Center Warsaw. Bounce for a few seconds when starting the engine after a long parking, probably indicative of the extension of the timing chain (timing) or the failure of the chain tensioner. " The timing and its components are monitored by electronic sensors that recognize the phase displacement and usually include a fault warning lamp. However, quite often you have to learn about stretching by ear.
