🧭 Before you start

Fits: Audi A5 (8T, 2007–2016), Audi A5 Cabriolet (8F), Audi A4 B8 (8K, 2007–2015)

• Special tools named: T40058
• Renewed: self-locking nuts

Don't miss

• Before installing gearbox, remove residue from threaded holes for engine/gearbox bolts in cylinder block using a thread tap.
• There is only one notch on the circumference; turn the torque converter accordingly.
• Check whether aluminium bolts securing engine to gearbox can be reused; if so, apply marking .
• The following step is necessary to ensure that the torque converter is straight and that it makes even contact with the drive plate.
• Use ring spanner insert AF 16V.A.G 1332/14 to tighten bolts.

🔩 Torque settings

Values can differ between engine variants — check the code stamped on your block.

ℹ️ Always cross-check the exact figure against your vehicle's factory manual before final tightening — a wrong torque can damage the engine. These values are extracted from workshop data and may not cover every variant or revision.

📋 Procedure

1. Tighten earth stud (1) to 9 Nm. — 9 Nm (6.6 lb-ft)
2. Tighten nut (arrow) to 9 Nm. [Note: Renew the bolts tightened with specified tightening angle.Renew self-locking nuts and bolts as well as seals, gaskets and O-rings.On vehicles with automatic gearbox 0B6, no needle bearing should be fitted in the drive plate. Before installing, check whether a needle bearing is fitted. Press needle bearing out of drive plate .Hose connections and air pipes and hoses must be free of oil and grease before assembly.Secure all hose connections with the correct type of hose clips (same as original equipment) Electronic parts catalogue.To ensure that the air hoses can be properly secured at their connections, spray rust remover onto the worm thread of used hose clips before installing.Fit all cable ties in the original positions when installing.] — 9 Nm (6.6 lb-ft)
