Fits: Audi A6 C6 (4F, 2004–2011)

• Special tools named: VAS 5051

Don't miss

• Before installing control motor, check air flow flap mount and connecting element (D).

📋 Procedure

1. Check position of control motor shaft (B) (must be in position shown). [Note: Connecting element (A) is only to be attached in the position in which it engages without having to exert force. If pre-tension is required to insert connecting element, check motor shaft (B) as this may be turned through 180°.If the motor shaft (B) is not in the position shown (only position in which the connecting element can be attached), use an adapter cable for example or a test lead from the adapter setV.A.G 1594/C to connect contacts 5 and 6 of the control motor by way of a 5 A fuse to a 12 V battery. Turn the control motor until the shaft is in the position shown (no pre-tension required to attach the connecting element). The direction of rotation can be reversed by interchanging positive and negative.Control motor shaft (B) has no stop. It rotates constantly if voltage is applied between contacts 5 and 6. Consequently, voltage should only be applied with control motor detached if connecting element (A) has been attached or to move shaft to correct position if connecting element cannot be attached.Shaft may be incorrectly positioned if pre-tension is required to insert connecting element (A) in control motor.]
2. Before installing control motor, check air flow flap mount and connecting element (D).
3. Check position of shaft (E) of air flow flap control motor V71 (must be in position shown). [Note: Check positioning of connecting element. There must not be any clearance between mount of control motor (A) and connecting element (B) (remove connecting element if necessary).Connecting element (A) is only to be attached in the position in which it engages without having to exert force. If pre-tension is required to insert the connecting element, check the mount of the motor (B) as this may be turned through 180°.]
4. Attach connecting element (A) to shaft of air flow flap.
5. Install control motor (C).

6. Hand-tighten bolts (A) (10 Ncm).
7. Plug connector (B) to control motor (C).
8. Before fitting upper cover of air intake unit, check correct attachment of connector (B) and routing of wiring.
9. Re-install components removed in reverse order.
10. Interrogate the fault memory of the operating and display unit, Climatronic control unit J255 and erase any faults displayed "Guided fault-finding" function of vehicle diagnostic, testing and information system VAS 5051.
11. Perform air conditioner basic setting and final control diagnosis "Guided fault-finding" function of vehicle diagnostic, testing and information system VAS 5051.
