FAQ – Volkswagen Jetta VI Wiring Kits

Which should I choose: 7-pin or 13-pin?

7-pin covers basic lighting. For accessories, charging feed or permanent live, choose 13-pin.

Will coding be necessary after installation?

Often yes—especially on cars with PDC, lamp monitoring or extended comfort features. Coding ensures proper system recognition.

Does the kit support bulb-failure monitoring?

Yes—our vehicle-specific kits are CAN-Bus ready and report lamp faults correctly where supported by the Jetta VI.

Can I install the kit myself?

Skilled DIYers can install many kits. For perfect integration and any required coding, a professional workshop is recommended.

What is permanent live used for?

To power accessories such as caravan interior lights, coolers or chargers. It’s not required for basic lighting alone.
