Actually, the torque specified in the factory service manual is 13.0 mkp AND 94 lb-ft ... the 130 Nm is a 'rounded up' translation using a conversion factor of 10, instead of the correct 9.81, so there is your 2% error and 96 lb-ft rating used in some places in Bentley! That Bentley also lists 94 lb-ft is other places is a bit confusing! The spec books note the discrepancy from using the incorrect conversion factor, and basically say that the 2 % error is 'good enough!'
