CAYENNE TURBO S) > TECHNICAL VALUES > GENERAL OVERVIEW
Information
The tightening steps in the tightening sequences relate to tightening screws uniformly, i.e. all
affected screws must first be tightened uniformly to the first torque value, then all screws are
tightened one stage further, and so on .
Replace all O-rings following removal!
The torques in the table below generally apply to screws that are not specifically listed =>
The bolt quality is indicated on the screw head at the top as a decimal number, e.g. "8.8" or
"12.9" .
Bolt quality 8.8 Bolt quality 10.9 Bolt quality 12.9
