Technical characteristics


Doors are screwed on hinges as a whole by three bolts TORX (arrow).

The adjusting control sizes of "a support of assembly knots of a door (1). The external sealant (3) should adjoin on all length to a forward door pillar and to a decorative lath (2) roofs. The distance between a decorative lath of a roof and a bottom edge of a sealant (3) should make and = 18,3 mm. Glass of a door (4) should plunge into a sealant on in = 5 mm.

At the expense of easing of bolts TORX (1 and 2) it is possible to shift a plate of the lock for lateral adjustment behind on a door.

In Audi doors, two-piece are traditionally put. The internal part of a door – a support of assembly knots of a door – is attached to an external part of a door – a door basis – four bolts. At the expense of it at a small damage it is possible to replace an external part, without dawdling with демонтажем mechanisms Glass lifts and деблокировки.

Care of a sealant of doors

External уплотнители which are in one plane with doors, in Audi A4 require special leaving since cracks in them cause not only thinnesses, but also raised шумообразование during movement. The best conditioning agent behind sealants is олений fat. It has a pleasant by-effect: in the winter it does not suppose примерзания a sealant to a body that relieves of burdensome warming by its hair dryer.

Door dismantle


  1. To disconnect штекерные sockets динамиков at doors, the electric drive of adjustment of a mirror or Glass lifts, it is necessary to remove its facing how it is described in this chapter. The same concerns wires and hoses of the central lock.
  2. Take out from clips сильфон between a door and a door pillar and extend from a door the disconnected wires.
  3. Unscrew in the top loop one bolt TORX, in the bottom loop – such two bolts, remove a door. Loops remain on a body.
  4. After installation adjust a door (the following section).

 Council: the Door can be dismantled together with all loops. In this case it is necessary to dismantle facing of a forward door pillar and to disconnect located under it штекерный a socket. Only so it is possible to reach the bolt of the bottom loop screwed up from within.

Correct adjustment of doors


  1. At adjustment of doors Audi A4 should stand horizontally on the earth all four wheels. In the lifted car the body can be bent a little, therefore юстировка doors will not be correct.
  2. Adjustment is carried out by following criteria:
  3. The sizes of cracks at forward and back edge of a door should be the following: a wing at a forward door of 4 mm, a forward door at a back door of 5 mm, a back door to a lateral detail of 3,5 mm. Establish doors correctly.
  4. The body contour should be sustained: longitudinal пеленг consists in that metal edges of doors were not allocated on a contour of a body with a step or that the door has not been established too highly or too deeply.
  5. It is necessary to avoid wind noise. It can achieve by correct adjustment of a door: for this purpose, first of all, it is necessary, that the frame of a window with the lining densely adjoined to a doorway. It is reached by adjustment of "a support of assembly knots of a door.

Door adjustment

Here adjustment of forward doors is described. To back doors, naturally, it too concerns.

Sequence: begin with adjustment of a back door if both doors are dismantled. If the back door was not dismantled and still correctly adjusted, it is possible to begin with a forward door.


  1. Longitudinal adjustment for installation of a door crack: slightly ослабьте loop screws
    Doors/doors so that still could be shifted a door.
  2. Close a door and level a crack.
  3. Cautiously open a door and tighten screws of hinges.
  4. Adjustment on height (contour): ослабьте as it was already told, screws between a loop and a door. Shift a door upwards or downwards.
  5. Again tighten screws.
  6. Lateral adjustment, door first line (wind noise): it is not regulated – in case of need it is necessary to make intermediate plates of metal and to insert between a door and a loop to put forward a door further outside.
  7. Lateral adjustment, back edge of a door (wind noise):
  8. It is a little ослабьте a plate into which the door lock enters.
  9. Close a door and press it into an aperture according to an external contour.
  10. Open a door, tighten a lock plate.
  11. Check up in salon, whether the door in regular intervals adjoins to the rubber sealant.
  12. Adjustment of a window frame: if the door basis is adjusted correctly now it is checked, whether in a doorway the window frame purely sits. Thus the external sealant of a door not должена to be put out over a roof lath.
  13. If it is necessary to adjust, dismantle facing of a door and ослабьте four fixing screws support of assembly knots of a door.
  14. Close a door.
  15. Let your assistant will press a frame outside
    In a doorway – it is better to press it hardly further since the rubber sealant of a door renders противодавление.
  16. That уплотнители adjoined densely, simultaneously with it you should wring out a frame upwards and forward.
  17. If adjustment correct it is possible to screw up from within both top bolts and back bottom bolts. The inhaling moment: 30 Nanometers.
  18. Consider in addition: the adjusting wedge at the bottom bolt ahead should be put always. Before a tightening of a bolt it needs to be shifted upwards so that it has slightly jammed.
  19. There is an additional possibility of adjustment of back edge of a door an adjusting wedge: at the expense of deeper latch of a wedge the door bottom edge leaves inside, and top – outside. Stronger вытягивание a wedge causes opposite reaction.
