Removing and installing drive chain for auxiliary drives on vehicles up to 04.2006 — AUDI

🧭 Before you start

Fits: Audi A4 Cabriolet B6/B7 (8H), Audi A4 B6/B7 (8E)

• Timing position: the crankshaft or camshaft is set and locked during this job
• Special tools named: locking pin

Don't miss

• After the gearbox has been removed the engine is supported with support bracket10-222 A and the stop for the torque reaction support is detached.
• Make sure that the lock carrier is installed on the vehicle before performing the following steps. — Detach support bracket10-222 A from engine (attached previously in order to remove gearbox).
• Place a washer under the bolt heads to make sure the chain does not get trapped by the bolts. — Attach special wrench T40049 at rear end of crankshaft using two old securing bolts (arrows) for dual-mass flywheel.
• To avoid any risk of injury, do not rotate the crankshaft while feeling for the TDC hole with your finger. — Turn crankshaft in normal direction of rotation to TDC position.
• Mark running direction of drive chain for auxiliary drives with paint.

🔩 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.
