Fuel economy on my 2016 132tsi Alltrack has been worsening of late and I can’t work out why.

Nothing has really changed in terms of driving habits or fuel, but I’ve gone from averaging around 8-8.5l/100km to 10-10.5l/100km on U98 with mainly urban driving.

Only thing I can think of is perhaps the age of the car? I’ve owned it for 2 years and have just clocked over 100k, averaging about 12k/year.

Other than that, I’m stumped. Any ideas or similar experiences?
