Experience turbo lag and power surge during road tests; check for significant oil accumulation at the turbo intake and intercooler connections (slight oil vapor is normal); and use OBD to read the real-time boost pressure peak to see if it meets factory settings.

We will never perform blind deep disassembly unless there are clear severe fault codes or extreme noises. The sealing of the engine and transmission is crucial, and compromising the factory seals to investigate non-existent issues is unprofessional. We rely on data flow and external acoustic and fluid analysis to make judgments.

We have established a database of target country policies. Check the specific requirements of the destination country in advance regarding vehicle age (left-hand/right-hand drive), emission standards (Euro 4/Euro 5), and steering position (left-hand/right-hand drive) to avoid customs clearance issues upon arrival.
