Hello and welcome to justanswer
These are fairly reliable cars and the main issues that seem to come from them is a issue with the fuel gauges over reading how much fuel is in the tank. The fuel range is usually quite accurate so it's worth checking this against how much fuel the gauge says is in the tank, also the needle doesn't always return to the zero mark.
There have been some issues on the DSG gearboxes and there are not many parts available for the gearboxes which makes them expensive to repair or replace. I would make sure that the oil and filter on the gearbox has been changed as these very often get forgotten about along with the oil and filter on the Haldex unit on the rear Diff.
I hope that this helps and if I can help further please feel free to ask
Many Thanks for your help, should I get these looked at immediately?
I would first check your service book to see if any of the oil and filter changes have been done. They are usually due every 40,000miles.
The fuel gauge you can easily check yourself by having a quick look at where it reads with the igniton key removed. If it reads above the zero line then you have a problem with it. If it starts at the lowest point then the odds are that it's working ok.
