The doors are bolted to the hinges as a whole with three TORX bolts (arrows).
Installation control dimensions «door mounting brackets» (1). External seal (3) must lie along the entire length of the front door pillar and decorative strip (2) roofs. Distance between roof trim strip and bottom edge of seal (3) should be a = 18.3 mm. door glass (4) must be immersed in the seal for ν = 5 mm.
By loosening the TORX bolts (1 and 2) you can move the lock plate for side adjustment on the back of the door.
Audi traditionally has two-piece doors. The inside of the door - «door mounting support» – attached to the outside of the door – «based door» - four bolts. Due to this, in case of slight damage, it is possible to replace the outer part without the hassle of dismantling the window regulators and unlocking mechanisms.
Door seal care
External seals, which are in the same plane as the doors, require special care in the Audi A4, because cracks in them cause not only leaks, but also increased noise generation during movement. The best way to care for seals is deer fat. It has a pleasant side effect: in winter, it does not allow the sealant to freeze to the body, which eliminates the burdensome heating of it with a hairdryer.
Dismantling the door
1. In order to disconnect the plug connectors of the speakers in the door, the electric drive for adjusting the mirror or the power windows, you need to remove its lining as described in this chapter. The same applies to the wires and hoses of the central lock.
2. Remove the bellows between the door and the door post from the clips and pull the disconnected wires out of the door.
3. Unscrew one TORX bolt in the upper hinge, two such bolts in the lower hinge, remove the door. The hinges remain on the body.
4. After installation, adjust the door (next section).
Tip: The door can be removed with all hinges. In this case, the front door pillar trim must be dismantled and the electrical connector located underneath must be disconnected. This is the only way to get to the lower hinge bolt screwed from the inside.
Correct door adjustment
1. When adjusting the doors, the Audi A4 must be level on the ground with all four wheels. In a raised vehicle, the body may be slightly bent, so the door alignment will not be correct.
2. Adjustment is carried out according to the following criteria:
3. The dimensions of the slots at the front and rear edges of the door should be as follows: fender at the front door 4 mm, front door at the rear door 5 mm, rear door to side piece 3.5 mm. Install doors correctly.
4. The contour of the body must be maintained: the longitudinal bearing is to ensure that the metal edges of the doors do not stand out on the contour of the body with a step or that the door is not installed too high or too deep.
5. Wind noise should be avoided. This can be achieved by properly adjusting the door: for this, first of all, it is necessary that the window frame with its gasket fits snugly against the door opening. This is achieved by adjusting «door mounting brackets».
Door fit
This describes how to adjust the front doors. Of course, this also applies to the rear doors.
Sequence: start by adjusting the back door if both doors are dismantled. If the rear door has not been dismantled and is still correctly adjusted, then you can start with the front door.
1. Longitudinal adjustment to fit the door gap: Slightly loosen the door/door hinge screws so that the door can still be moved.
2. Close the door and level the gap.
3. Carefully open the door and tighten the hinge screws.
4. Height adjustment (circuit): loosen, as already mentioned, the screws between the hinge and the door. Slide the door up or down.
5. Tighten the screws again.
6. Side adjustment, front door edge (wind noise): not adjustable - if necessary, you need to make intermediate plates of metal and insert between the door and the hinge in order to push the door further out.
7. Side adjustment, rear door edge (wind noise):
8. Slightly loosen the plate that holds the door lock.
9. Close the door and press it into the opening according to the outer contour.
10. Open the door, tighten the lock plate.
11. Check up in salon, whether the door evenly adjoins to the rubber sealant.
12. Window frame adjustment: if the door base is adjusted correctly, it is now checked whether the window frame sits cleanly in the doorway. The outer door seal must not protrude above the roof strip.
13. If you need to adjust, remove the door lining and loosen the four fixing screws «door mounting brackets».
14. Close the door.
15. Have your assistant press the frame from the outside into the doorway - it is better to push it a little further, because. the rubber door seal exerts counterpressure.
16. In order for the seals to fit snugly, at the same time you must press the frame up and forward.
17. If the adjustment is correct, both upper bolts and rear lower bolts can be screwed in from the inside. Tightening torque: 30 Nm.
18. Note additionally: the mounting wedge at the lower bolt must always be placed in front. Before tightening the bolt, it must be moved up so that it is slightly wedged.
19. There is an additional possibility of adjusting the rear edge of the door with an adjusting wedge: due to the deeper latch of the wedge, the lower edge of the door goes inward, and the upper one outward. Pulling the wedge more strongly causes the opposite reaction.
