The Dangers of Using Non-Certified Services for Car Repairs: A Warning for BMW, Mercedes, Renault, and More

New cars that are repaired in non-certified services become unusable. “Such victims come to us more and more often,” said a representative of a car dealer.

The problem has already affected BMW, Mercedes and Renault cars. According to the source, when connecting the diagnostic equipment to the 2023 BMW X3, which is not officially supplied to Russia, all the warning lights on the control panel lit up at once: low tire pressure, discharged battery, etc.

“The car had to be evacuated to the official dealership. Our diagnostic equipment showed that the car locked because it “appeared” stolen. We had to reset the car’s software and recheck all car parameters with an alternative method,” the source said.

He added that it was possible to unlock the car only because the system had not yet been re-rooted and third-party software had been installed.

The problems started for the BMW X5 model after the media system and control panel were re-Russianized. “It was not possible to see either the speedometer or the fuel consumption, it is impossible to drive without it. Resetting the software to the original version helped again. In addition, the customer himself refused to reflash the system. As a result, thanks to the original version and the key, it was possible to recover the original version in German,” he said the source.

After leaving Russia, foreign car companies began to disable diagnostic equipment and stopped supporting software in the country due to the war in Ukraine and sanctions. In addition, when connecting the diagnostic equipment to the car, there is an exchange of codes. If the information matches, then the machine analysis is started, if not – it is blocked.

Also, the owners of many vehicles manufactured in the West have lost the opportunity to make a duplicate key and find out the maintenance history. This problem has affected Volkswagen, Mercedes-Benz and BMW premium class models as well as popular middle class cars KIA and Škoda.
