Like Brighton I planned a second had IS 220 D next year - but reading this site makes me think again. Although, as noted you do't get topic noting satisfied owner has nothing to post. The issues related to the 5 th injector, egr value and 1 & 2 gear, as well as the mpg makes me think I should look at Honda's.
My parameter for success is to spend abou £ 15 k cash and keep for 3 years - I expect that my purchase will be trouble free up to at least 50 k miles and I replace the consumables - tyres, exhaust and pads - but not discs. I do 40 miles per day to work, it looks like the mpg of the 220D will be about the same economy as my current pile of French junk. I'm minded of the 220 D Sport as its a better drive acording to this forum.
