Just under 45mpg (indicated) on a return trip to the Metrocentre (31 miles) on uncluttered roads and felt a little low on power, back down to the levels experienced with V-power. It has been poor for a few days now with a regen going on for my last few commutes, but not today. Absolutely sh!te - an easy 53mpg journey in my Scirocco. My tyre pressures are spot on and i've checked the air filter to make sure it hasn't been put in backwards or something daft like that. I have done about 1500 miles now.
Going to book an appointment with the dealership to get them to look at my low mpg and power, sort the dash rattle/buzz @1500rpm and sort my squeaky front drivers side shock out. I'm sure there's something else minor to sort out too, but can't think what it is. When I had my 170TDI PD MK5 Golf, that was plagued with DPF regens and low mpg until they gave it an official service remap that sorted everything, Maybe more of the same is required.
If i'd have known I would be looking at the realms of 40-43mpg (actual) for a GTD, I'd have got a GTI and aimed at a realistic 35mpg. If the situation doesn't improve, this will be the last TDI I buy.
