2017-2026 Bisu Series: M3, T3, T5

Many repair shops encounter Bisu vehicles. Although the brand has ceased production, plenty of M3, T3 and T5 models are still in service on the road. The biggest headache for technicians is the lack of technical documentation; valid files available online are extremely limited. When faced with engine overhaul, electrical leakage, chassis abnormal noise, interior disassembly and other issues, technicians have to rely purely on experience without reference manuals. This not only wastes time but also easily causes assembly and disassembly errors.

Whether performing timing calibration, engine cylinder inspection, troubleshooting wiring faults, or removing dashboards, door panels and sunroofs, the absence of diagrams and disassembly procedures greatly restricts repair work. Many technicians feel troubled when receiving Bisu vehicles due to the lack of repair references.
