Why cars show “breakdowns” in the electricity after detailing
Detailing is becoming more and more popular among owners of expensive premium cars. Dry cleaning and body polishing are especially popular these days, now that even wealthy citizens have started saving. However, after visiting such a workshop, problems often arise. About this – in the material of the portal “AvtoVzglyad”.

The vast majority of iron horse maintenance requires good lighting in the hangar. And even if the lamps were not kept initially, there are still situations where there is not enough light. Then the masters act simply: they use the optics of the car. Or, as soon as the car enters the box on the cabin “moidodyr”, all the doors open and the “light music” burns for several hours.

Premium cars, such as the BMW X7 or the Mercedes-Benz E-Class, have a so-called “sleep” function. It is designed to prevent battery drain. But even the Germans did not come up with protection against unfortunate masters. Once the car “falls asleep”, the detailers press the “start-stop” button and everything continues to work. As long as the battery doesn’t land “at zero”.

Realizing the problem, the employees start the engine using a portable charger and hand the iron horse shiny clean to the customer. He leaves satisfied and after a while he encounters “inexplicable” problems.

For example, the mentioned BMW X7 may have a ‘glitch’ speedometer, which indicates 0 km/h while driving. Or the instrument panel refuses to turn off when the driver closes the doors with the key. These and other electrical disturbances occur just after the work of the “charger”. After all, manufacturers of many premium cars do not recommend using it. What can I say: even in the latest generations of Volkswagen Passat, it is prescribed to maintain the batteries only in official maintenance.

As a result of an abnormal intervention, the electronic units begin to “panic”. And not all systems come to their senses after that. It seems that the solution is elementary – reset the terminals and reconnect them. But not everything is so simple. Modern batteries do not like chronic undercharging – they “die immediately”. As a result, you will have to spend 50,000 rubles and buy a new battery.

Therefore, in order not to lose money on spare parts and diagnostics, entrust your car only to a proven service. Or at least take a closer look at the reviews on the network.
