Gas mileage problem

Hi guys,
I have been experiencing pretty weird (mildly speaking) issue with gas mileage for a while. I have Compass Rallye 2007, 2.0 CRD (Volkswagen diesel engine). I know that you are not so familiar with engine, but I hope you can give me some advice.
During my first year with Compass (bought it in April 2011) I used to have average city fuel consumption of 10-11 l/100km (21.3 - 23.5 mpg), except for very hot summer days, when it went up to 12.5-13 l/100km (18.5 mpg) because of mass AC usage. But, in last year (June 2012 - ) I managed only 13.5-14.5 l/100km (16.2-17.4 mpg) during regular days and it`s deteriorating, to above 15 l/100 km (15.7 mpg) in summer. I think that these results are pretty bad, considering that this very same engine in VW Passat/Golf or Audi can return city average of 10 l/100km (23.5 mpg). The results in highway have not changed much, but have changed. They used to be 6.5-7.0 l/100km (33.6-36.1 mpg), and now they are 7-8 l/100km (29.4-33.6 mpg). What can be causing this?
I am not a long distace crosser, drive only about 10-15 K km in a year (6200-9300 miles), most of it in a city. Also, this car produced a lot of mechanical and, especially, electrical issues during these 2 years. Exactly a year ago, I changed TIPM (500=651$) plus some thing, in my domestic language, called "electric installations hub" or "electric installations relay" (located behind left front wheel) which also cost 500, but I bought used one for 10. This may be a misleading clue for you, but I had to mention it. Other mechanical issues were not related to engine (struts, tie rods, silent blocks,...).

Thanks for reading, hope for some help.

Recency of transmission fluid change and tire pressure come to mind first.
