Hi, so always had this problem of fuel level never reading full. Even filled up to the brim but level never went up to full. So I had recently cleaned out the main tank and the pump and thought it might have improved but this didn't work out.

So used the vcds and did an instrument cluster...

New to the VW world (aircooled Porsches are my normal money pit) but bought this car off a friend who was trading in to buy a new car.

This is a 2011 gti.. dsg.. the fuel gauge works when you start it, but after 5 mins, it goes dead.. If I restart the car, the gauge works again, and then...
