arrrrr .. getting VRS ready for 10 days away ..

lights & levels checked, cleaned in and out , rear kids DVD's set up

putting genuine skoda roof rails on and forgot that the tool i used to tighten bars up is rounded off so last time i used a normal alan key, causing slight damage/cracks to roof now cant find instructions to see what the torque settings is ... so does anyone out there in friendly skoda land know the torque setting for the roof rails on a h/c octavia VRS

thanks

It says 4Nm on the end of the allen key I got with my Skoda roof bars.
