If you are looking to rebuild the 4.2, I'd suggest you go with this one here 👉 Audi A6 Service & Repair Manual.
This one fully covers the 4.2L engine, and provides the steps for measuring piston ring gaps, inspecting cylinder tolerances, or reassembling internal components. It includes torque specs, clearance values, step-by-step disassembly and reassembly instructions, basically everything you might need to rebuild/overhaul your 4.2L.
Hope that helps!
