The upgrades/updates may have been made in haste due to the queue so it is entirely possible that the hoses may be working around a bit once you have driven it for a while. Get it up on a ramp at a local garage/tyre place and check them? It will be quicker to drop them £40 for 30 mins on their ramp and a spanner check?
You can't even see the hoses with the bodywork on....
And they don't use a jubilee style clip- the hose ends follow BMW practice as did the Aero's with a molded plastic end with an o-ring seal and a sprung retaining clip
