4S dealership records are directly connected to the manufacturer's database, making the data hard to tamper with and the most reliable, with original parts guaranteed; third-party repair shops usually are not connected, making their data unverifiable. Therefore, we only consider the connected records from 4S dealerships as valid historical documentation.

Most basic maintenance reminder lights (like for changing the air conditioning filter) can be manually cleared using a combination of steering wheel buttons or through the engineering mode on the central control screen. We will provide internal guidance manuals for these hidden operations to our B2B clients.

We can only infer from the existing connected maintenance records. If the records show continuity and adhere to the recommended maintenance schedule, we will assign a high credit score; if there are gaps of tens of thousands of kilometers, we will assume it was not well maintained during that period and alert you.
