Modern Start/Stop systems significantly strain the electrical system. When the engine stops, electrical consumers (radio, air conditioning, lighting) continue to operate, which can quickly drain the battery. Upon restart, the alternator must supply a large current very quickly to charge the battery and supply all systems.
As a dedicated Start/Stop alternator, the IST80S058 offers the following advantages:
Higher charging current (230A): This high capacity ensures that the battery recharges quickly even after short engine stops, maximizing system uptime.
LIN Protocol Compatibility: Start/Stop systems often communicate with the Engine Control Unit (ECU) via the LIN (Local Interconnect Network) protocol. This alternator supports this communication, enabling intelligent charging control that optimizes energy consumption and protects the battery.
Reliability: The quality of Valeo parts guarantees a long service life and continuous, flawless operation, reducing service times.
Based on the OE part number 06L903018G, this alternator is primarily designed for vehicles from the Volkswagen Group (Volkswagen AG) equipped with a Start/Stop function. Stremtec's wide product range covers the needs of the most diverse starter motors and alternators, including repair solutions for Audi starters/alternators.
Important Note: For precise compatibility verification, it is always recommended to cross-reference the above OE and Valeo part numbers with the vehicle's chassis number (VIN) and the codes of the existing part.
