Hello, can anyone help please? I am fitting a towbar to my 2008 A6 C6 Allroad and need to remove the plastic tray in the luggage area, but there is a pressure tank connected via a pneumatic pipe stopping me. Can I just disconnect it? Will it re-pressurise when re-connected and engine is running? Afraid to just disconnect it as I suspect it may be at quite a high pressure and damage something. Thanks for looking.
