WARNING: This page is about a different car, the 2006 Audi A4, 2005 Audi A4, 2004 Audi A4, 2003 Audi A4, and 2002 Audi A4. However, it is still accessible from the selected car via links, so may be relevant.
Installation is the reverse of removal, noting the following:
NOTE:
- All cable ties opened or cut during engine removal must be reinstalled at the same locations during installation.
- Replace gaskets and self-locking nuts.
- Wires of oxygen sensors must always be secured in the same position when installing so that contact with the exhaust pipe is avoided.
- Install exhaust system free of stress. See ALIGN EXHAUST SYSTEM TENSION-FREE (VEHICLES WITH FRONT WHEEL DRIVE) and ALIGN EXHAUST SYSTEM TENSION-FREE (VEHICLES WITH ALL WHEEL DRIVE) .
