New Rad.......Bonnet off ?

[Rower]

I have a leak on my rad, one of the seams has split, as some re-soldering work was done on it about 3 years ago I reckon it needs replacing, my question is can I do the job without removing the bonnet, which I really do not want to do!
Any advice gratefully received.The car is an S3.
