Installation:

The tightening torque to be set 51 37 2AZ in 51 37 SIDE WINDOWS, ELECTR. ACTUATED (MDE) is reduced when special tool 51 3 240 is used. Depending on the torque wrench used, this must be calculated according to the adjacent equation:

MDE Torque to be set

MDV Prescribed torque (without special tool)

lj = Standard adjustment length with adjusting tool

l1 = Effective length of torque wrench

l2 = Inside dimension of adjusting tool

lw = Inside dimension of insertion tool (here lw = 246 mm+l2)
