As I mentioned last month I went through the recall process. Got the new 5th injector - although I've never had a problem or limp mode, and the consumption was very good.
As first I've noticed change in the idling. I am still not sure how exactly it is now, but my observation is: it still idles at 1100 till the operation temperature is reached, however if I stop the car, for example for 2 hours, the temperature decreases to 1/5, but now it idles all the time at 800 - even when the operation temperature is not reached.
Second observation is the consumption. I know it is too soon to have final verdict after one tank, but I have mention that. This tank I was driving in the city more than ever. Usually I drive (urban-extra urban-higway) 20%-40%-40%, but this time it was 40-50-10. Already the BC indicated optimistic number (6,8l/100km;41,5mpg) - I expected worse numbers after so much of urban driving.
To my surprise, after refuelling and real calculation the consumption is 6,56l/100km (43mpg) - my best consumption since september 2007!
