2013 Audi TTS 4WD, registered in December 2014, features a high-power EA113 engine, a 6-speed Stronic transmission, and a high-power output of 200 kW (272 hp). It also includes a factory-installed BOSE sound system, electromagnetic suspension, and a 90-day buyback guarantee.
Once the car system (especially in a closed ecosystem) undergoes a major version upgrade, its bootloader is usually locked, preventing downgrades. If this happens, there is basically no solution in an overseas environment. Therefore, we strongly warn: do not blindly insert a USB drive to upgrade while offline.
We conduct basic visual inspections and freezing point tests. If the antifreeze's freezing point is insufficient or the engine oil is severely degraded, we will document it. However, considering the shipping duration, we strongly recommend a comprehensive "Full Fluid Service" upon arrival.
Obtaining precise internal resistance at different SOC levels requires disassembling the battery pack and connecting it to a professional charge-discharge cabinet for several days of cycling tests. This is beyond the scope of non-destructive used car inspections; we only provide real-time estimated internal resistance data based on OBD port readings.
