FAQ – Volkswagen Passat B7 Wiring Kits

Should I go with 7-pin or 13-pin?

If you're only using basic lighting, a 7-pin wiring kit works. For powering accessories or permanent live, a 13-pin set is better.

Does my Passat B7 support lamp-failure monitoring / Check-Control?

Yes—if your car has Check-Control or similar systems. Our kits support detection and warning of lamp failures.

Is coding required after installation?

It depends on your vehicle’s equipment. If it has comfort features, parking sensors or lamp monitoring, coding is often needed to ensure all functions operate correctly.

Can I do the installation myself?

With some technical skills and the right tools, yes. For secure cable routing, correct connections and full functionality, a professional workshop is recommended.

Is permanent live absolutely mandatory?

Only if you have accessories that need continuous power (like interior lights, chargers, etc.). For pure lighting functions it’s not required.
