Technical characteristics


The gas-filled shock-absorber (1) cowl of Audi can be dismantled after removal of a lock washer (2) and removals of an eye of the hinge from a finger.

     Council: if the same cowl is established, at a pulling of a wire fix a cord on its end. Stretch a cord with a wire through a cowl. The cord remains in a cowl and will help to involve a wire at installation.

  2. Disconnect a hose of system of washing of glasses.

At the correct installation the cowl has to adjoin to these shock-absorbers (shooter) densely. For adjustment of height the shock-absorber is screwed up or unscrewed.

Figures "1" and "2" designated reverse sides of bolts which have to be weakened for adjustment of the lock of a cowl on height.

If the locking bracket of a cowl enters the lock not precisely, it can be shifted after weakening of bolts with six-sided heads (1–3).

To replace a cowl cable, weaken bolts with six-sided heads (1 and 2). The cable (4) is on sale only together with the handle (3).

Adjustment of a cowl

When the cowl is closed, the distance from it to both wings has to be identical (about 3 mm), and on a first line it has to be in one plane with wings. Besides, adjustment on height too has to be correct.


  1. For adjustment in the longitudinal direction bolts above between the hinge and a cowl are weakened.
  2. For lateral adjustment bolts between the hinge and a body are weakened.
