  2. Dimension B = 4.5 mm +/- 0.5 mm.
  3. Dimension C = 0 mm+ 1 mm flush when running parallel to body.

Adjusting in relation to body contour

  1. Longitudinal adjustment is achieved by loosening hinge bolts arrow -A- on A-pillar on upper and/or lower door hinge and by moving doors -2- (oversized holes in hinge or in A-pillar)
  2. Tightening torque 32 Nm

Adjusting in relation to vehicle center

Note. A collared shoulder bolt is installed into door side of upper and lower door hinges. During repair work, adjustment is therefore generally not required. If adjustment is necessary nevertheless, shoulder bolts can be replaced by bolts of the same size, length and strength (available in Parts List).

  2. Tightening torque 32 Nm NOTE: Adjust rear area of door (in relation to vehicle center) by means of striker plate.
  3. Loosen bolts -2
  4. Use marks arrows -a- or arrows -c- for lateral adjustment.
  5. Move striker plate -1- until door shell is flush with body contour. NOTE: Position may only be adjusted with respect to center of vehicle and not in terms of height.
  6. Use marks arrows -b- or arrows -d- for height adjustment.
  7. When correctly adjusted, striker plate must advance centrally into door lock.
  8. Tighten bolts to 25 Nm.

Making improvised gauge

  1. Make improvised gauge (e.g. plastic or plywood) in line with specified dimensions.
  2. Dimension -a- = 4 mm
  3. Dimension -b- = 30 mm
  4. If door subframe has been properly adjusted, gauge placed approx. 200 mm from B-pillar must make contact with both door window and roof trim strip over a length of approx. 365 mm.
