Just got it back and something really wierd happened. Firstly the intercooler fault must have been developing very slowly so I did not notice the power dropping but now its a hell of a lot quicker. The wierd thing is a while back I posted this

I could not fill the fuel tank at all within 2 gallons of the top.
When I picked it up as I drove off I heard a strange bubbling sound so I went back to the garage. THey could hear it but not explain it. I drove away again 5 miles later noise had stopped. I pulled in to refuel and the dam thing came right to the top for the first time in 2 years, confirmed by trip computor reading 505 miles to empty.
The intercooler and fuel system are not directly related so what happened to my fuel tank. Anyone any ideas.
