General information
1. Front body panel / lock bracket - the name of the body part installed in front of the engine compartment. The hood lock mechanism, front bumper, radiator, automatic transmission fluid cooler and headlights are installed on this part of the body. The body structure of the Audi A4 is such that this part of the body can be removed without significant disassembly. In addition, the front panel/lock bracket can be moved a few centimeters away from the body by moving it to the 'maintenance' position", without disconnecting the various hoses, tubes and wiring that are attached to it. In this position, access to various engine and engine compartment components can be greatly improved.
Withdrawal
2. Disconnect the wire "masses" from the battery.
Note: If the radio installed on your car has a secret code, make sure you know it before disconnecting the battery. Contact your dealer if in doubt.
3. Remove the front bumper as described in paragraph 3.
4. Loosen the screws and remove the soundproof panel at the bottom of the engine compartment (pic. 10.4).
5. Disconnect the cable from the hood latch as described in paragraph 8.
6. Remove the mounting screws and disconnect the intake air duct with grille from the lock bracket (pic. 10.6).
7. Locate and disconnect the wiring connectors for headlights, headlight range control motors, direction indicators in the left corner of the engine compartment (pic. 10.7). Disconnect the wiring from the outside temperature sensor, located at the lower rear edge of the radiator, closer to the lower hose fitting.
8. Drain the coolant as described in the relevant part chapter 1, disconnect the cooling hoses from the radiator as described in paragraph 3 of chapter 3.
9. On models with air conditioning, remove the condenser from the lock bracket and tie it in a suitable place in front of the engine with wire or rope.
Warning: Do not leave the condenser hanging on the tubes, so as not to stress or damage them.
Attention! Do not disconnect the refrigerant pipes from the condenser (read the warnings in chapter 3, about the dangers of refrigerant).
10. Remove the power steering fluid cooler and tie it in a suitable place at the bottom of the engine compartment with wire (pic. 10.10). On models with automatic transmission, perform the same operation on the automatic transmission fluid cooler.
11. On turbocharged models, remove the mounting screws and remove the intercooler air duct from the front panel.
12. Release the front panel seal from both front fenders. There is no need to remove the seal from the panel itself.
13. Remove the two bolts securing the front panel to the top of both fenders (pic. 10.13).
14. Turn away bolts (one on each side that are under the front turn signals) attaching the panel to the side of both front fenders (pic. 10.14).
15. An assistant will be required for the final stage. Loosen the bolts of the front bumper mounting pipes (four on the right and three on the left). Remove the front panel forward from the car (pic. 10.15, a, b).
Installation
16. Installation is the reverse procedure. Check the operation of the front direction indicators, lock and hood safety hook. Fill and bleed the cooling system as described in chapter 1A or 1B. Check headlight adjustment.
Installing the front panel/lock bracket in position "maintenance"
Note: To perform this procedure, fabricate two accessory studs from a 300 mm bar and a set of nuts.
17. Disconnect the wire "masses" from the battery.
Note: If the radio installed on your car has a secret code, make sure you know it before disconnecting the battery. Contact your dealer if in doubt.
18. Remove the front bumper as described in paragraph 9.
19. Remove the fasteners and remove the front edge of the soundproofing panel from the bottom of the front panel. There is no need to completely remove the panel.
20. Turn away screws of fastening and disconnect air ducts with a lattice from the panel.
21. Remove the right top bolt from the right bumper mounting tube. Screw one of the auxiliary studs into the opened hole and screw the nut onto the stud horses. Screw the second stud into the hole to the left of the left bumper mounting tube (pic. 10.21).
22. Turn away the remained bolts of fastening of the forward panel, as it is described in pp. 13... 15 of the previous handed out.
23. Carefully pry the front panel away from the engine until the rear of the two bolts on each side of the top surface of the front panel align with the first of the two corresponding holes in each fender. Re-tighten the mounting bolts to secure the front panel. Adjust the nuts on the homemade studs so that the panel is held securely and does not hang from the top mounting bolts.
24. Panel installation - reverse procedure. Tighten all threaded fasteners to the prescribed torque. Check headlight adjustment.
