i havent done it on a mk5 to be honest, but i have with a mk4.
it really is a tough job, becuase you dont want to bend the headlining.
theres a lot of torx screws to remove around rear grab handles, rear lights etc. you will need to remove the C pillar covers too. and possible the B. that will give you enough room to move it outa the way without bending the lining.
then you'll need a 14mm (i think) spanner to take off the bolt, then pull the base out from the outside.
+ BHP for not spamming good sir? haha!
