This detailed product description presents the high-quality, factory new (OE New) 48V starter-generator unit (Integrated Starter Generator – ISG) manufactured by Valeo, specifically developed for modern hybrid vehicles. This component plays a crucial role in the vehicle's electrical system, supporting Mild Hybrid Electric Vehicle (MHEV) technologies such as the start-stop function and regenerative braking.
The Valeo IBSG4U087 is a generator designed for a high-power, 48V system that also functions as a starter motor. This dual function enables fast and efficient engine starting, as well as energy recovery during braking, significantly reducing fuel consumption and emissions. Valeo, as a leading automotive supplier, guarantees the quality and reliability of original equipment (OE).
This unit is the ideal choice for workshops and parts distributors seeking a premium category replacement part for repairing the 48V systems of Audi, Volkswagen, and other VAG group vehicles.
Excellent Starting Performance: The 48V system provides higher starting torque, resulting in faster and smoother engine starting, especially under cold weather conditions.
Efficient Energy Recovery: During regenerative braking, the system efficiently charges the 48V battery, optimizing energy consumption.
Start-Stop Function Support: Ensures seamless and nearly imperceptible engine shutdown and restart during traffic jams and stops.
Reduced Load on the Main Generator: The 48V system takes over the load of high-power electrical consumers, reducing the workload on the traditional 12V generator.
The IBSG4U087 model features extremely precise technical parameters that ensure perfect integration into the electrical architecture of the target vehicles.

Main Application Areas:
Start/Stop Systems: Ensuring the system's seamless operation.
48V Hybrid Systems: Support for electric assistance and energy recuperation.
LIN Protocol Communication: Support for modern vehicle's on-board network communication (LIN Bus) for data exchange with control units.
The Valeo IBSG4U087 represents a specialized area of modern vehicle repair that requires specific knowledge and components. Handling 48V systems differs from traditional 12V systems, thus installation must be performed by trained specialists.
Valeo is one of the largest global automotive suppliers, playing a significant role in the electrification and development of hybrid technologies. As an „OE New” product, the IBSG4U087 guarantees that the component meets the strictest factory quality and performance requirements. This reliability ensures the long-term, error-free operation of the vehicle in the area of hybrid functions.
Important Note: Working with 48V systems requires specific safety precautions. The system voltage can be hazardous and may require special diagnostic and service tools (e.g., Rotrix testers and tools) to check correct operation and for LIN protocol diagnostics.
The Stremtec offering also includes service and diagnostic support related to the IBSG4U087:
Diagnostic Tools: EV/PHEV diagnostic equipment for identifying system faults.
Training: Starter-Generator and Motoplat expertise for professional handling of modern systems.
Related Components: Further 48V units, such as the IBSG4W059 Valeo New 48V model are also available in our offering.
This product belongs to the „Generators” and „Starter Motors / Generators” categories and is found under the Valeo brand. Identification based on part numbers (e.g., 06Q903018, 615017) is crucial for compatibility.
