Thats pretty much it. I shall monitor the gaffer tape (for survival in rain etc) and renew as needed. At the next service I may go for the uprated ones those who have remaps go for but they cost a lot, or a dogleash fix as described on TDI forums but modified my leak is on the join halfway down and not at the turbo at the back of the engine.
A guy at work who is into boosting his MINI a lot suggests single piece uprated 'chav' (aka 'ricer') style ones but it will need some flex in it as the engine moves but the intercooler stays still.
