Central screw 27Nm / Noise detection

Hello, after the replacement (with the appropriate components and Klann), of the two RL on the Alhambra 1.9 / 115 hp, year 2001, 133,000 km, I tightened the driveshaft screw with a torque wrench, and then loosened it again. Then I tightened it to approximately 250 Nm. That was probably intended differently.
What should be the starting torque before I rotate it another 1/4 turn?

The distinct clicking noise from the wheel bearing is gone, but there is a slight, quiet, and rapid increase and decrease in wheel speed that is dependent on the speed, which is noticeable when turning slightly to the left, but not constantly audible while driving. I'm now thinking about the drive/intermediate shaft or gearbox engagement on the right side...
However, this has been occurring sometimes before the noise from the wheel bearing, according to a sensitive woman's statement. The driver hadn't noticed it.
Can someone confirm my suspicion?

Beim Sharan sind es 150Nm und dann 90°.
