Porsche 996 TT Repair Manual page 324

• The steering angle sensor actual value must be checked after a suspension alignment where no
changes were made to the wheel alignment values!
Note
The following values relate to the empty weight, i.e., full fuel tank, vehicle with spare
•
wheel/collapsible wheel (not GT2) and tools, but without driver and without additional weight.
• A caster adjustment is normally not necessary and is therefore not present.
The toe−difference angle value is also influenced by the vehicle height! For this reason the measured
•
result must be evaluated accordingly! No action is necessary in the case of small deviations from the
toe−difference angle required value, as long as the value to the right and the left is almost the same!
