Genuine Renault Megane 3 RS UPC Module (Protection Unit)

Why is the UPC Module vital for your Megane 3 RS?

The Protection and Switching Unit (UPC) is far more than a simple fuse box. It is the brain that distributes power to your headlights, engine management system, and all critical peripherals of your Renault Megane 3 RS. Without a perfectly functioning module, you risk losing essential functions or, worse, suffering a complete vehicle breakdown.

Risks of a failing UPC unit

Humidity, water ingress, or internal circuit aging can cause irreversible damage. By not replacing a faulty unit, you expose yourself to:

• A total electrical failure preventing the engine from starting.
• Random malfunctions of lights, wipers, or air conditioning systems.
• A risk of short-circuits that could damage other expensive control units (ECUs).
