Audi 4.0T Swap Wiring Diagram

Job ID: 40048556

Budget: $10 – $30 USD

I’m dropping a 2016 Audi S8 4.0 TFSI into my 2012 Audi A4 Avant and need one clear, consolidated wiring diagram focused on the engine-side ECU connections. I already have the factory schematics for both cars; your task is to merge the relevant information so I can wire the swap confidently without chasing every pin across dozens of pages.

The finished diagram must:
• be delivered as a high-resolution, print-ready PDF
• show every ECU power, ground, CAN-bus, sensor and actuator line required for a clean start-up
• include detailed, legible annotations that call out wire colors, pin numbers and connector locations

I’ll supply the original PDFs the moment we start. You return a single annotated diagram (and any editable file you work from if available) that I can hand straight to my harness builder and electrician.
