Haven't updated this for a while.
I noticed that the aerial seal was split and I didn't want to end up with a leak so I had ordered a new one from tps.
For those that would want a quick guide (5door)
Tools used
Trim clip remover
25 torx screwdriver
Torch
22mm spanner
10mm ratchet spanner
Magnet
10mm socket and ratchet
First removed the upper trim by using the trim clip remover and pulling downwards.
Then removed the airbag logos on the c pillar trims and removed the Torx 25 screws ( 1 each side )
Then removed the 2 10mm nuts and pulled the c pillar trims inwards towards the centre of the car
Once this is done used the 10mm ratchet spanner and removed the 2 10mm nuts holding the curtain air bag igniters in place and moved out of the way slightly so I could unplug the aerial. Then removed the 22mm nut on the bottom of the aerial and removed form the roof.
Then i slid the new seal on had to use a bit of wd40 as I didn't want to split the new one. Then refitted it all in the reverse order. Only a 30min job
New fitted
