I am not a mechanic but learning about my audi has become a hobby since they retired me from work.
I want to disconnect the fuel line that feeds the fuel rail which has the intetesting bolt on it to get better access to the nut holding on the valve cover on the passenger side. Is there a problem with just going ahead and doing it? I am concerned it may lead to problems.
Not well worded, l know. Any help for a newbe do it yourselfer would be greatly appreciated.
