Rear Wheel Bearing Housing Torque?

["Fred Munro" <munrof@isys.ca>]

    I just finished replacing the right rear wheel bearing in the S4. The
job went well - the hardest part was removing the ABS sensor without
destroying it in the process.
    Bentley calls for the bolts attaching the wheel bearing housing to the
trapezoidal arm to be torqued to 170 Nm plus 3/4 turn (135 degrees). Either
the 3/4 turn is right or the 135 degrees is right, but obviously not both.
    I assumed Bentley's math whiz figured there were 180 degrees in a circle
and I went with the 3/4 turn.
    Can anyone confirm which is correct?

TIA
