Personally I'd fix the know fault ('stat) and then see what results is. Can't make it worse! Then full scan with VCDS or similar to see if any faults showing. And check obvious things like tyre pressures and air filter (recall air filter is every third service which as I'm on variable interval would be every 54k or so, way too long, i'm old enough to remember when air filters were down every few K and paper filter technology hasn't changed that much in the 40 plus Years I've been driving. I change air filter every service (so about every 12 months) as a decent OEM filter e.g. Mann is just over a tenner from Halfords. Ditto fuel filter done every service, small cost but helps keep high mileage motor (175K) ticking over and hopefully helps avoid the big bills)

You also haven't said what sort of journeys the 35mpg was from and what engine you have. Genuine 35mpg (so likely closer to 40mpg indicated) might not be bad for short journeys in town (especially if yours is petrol) I struggle to get above 40mpg indicated on that sort of use.
