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.

The lifespan of rubber sealing strips for frameless doors is usually only 4-5 years. We carefully press the sealing strip at the edge of the roof to check for loss of elasticity and use a high-pressure water gun to wash the seams of the windows to check for direct water leakage due to aging.

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.
