Yes this a serious quality control issue. The Liquorice tube description is very apt. Mine was replaced by myself several years ago with Neoprene model aircraft fuel tubing. Very flexible and will remain so without perishing. If not caught soon enough serious damage occurs to the electrics - I have just had to have the lcd on the speedo replaced by the Carbeont Factory £50.
The dash is only held in place with three woodscrews and simple to remove. (2008 4/4) First remove undertray then adjust steering wheel to lowest position.
