Hello, the consumption of our Corolla Verso 2.2 D4 D-Cat is currently much too high. Bj2006. He did not pull down anymore. I read a lot in forums and then cleaned the agr (Toyota egr) valve and the cracker. Thanks for the instructions! Now he pulls again, even below 2000 revolutions. The part was totally dirty, the two valve flaps almost 1.5 mm open, and that in supposedly closed condition. I thought that would lower the consumption again, but that was not so We mostly drive short city routes. Here at present over 12L. On weekends but 100km highway at a distance. No matter what speed, also 110km/h constant, I can hardly get below 10.5L. That was earlier different. Remember me about the summer vacation, between 6.6 ind 7.5, around 130km/h. If I drive now 130 to 150, it is not possible at present under 11-12L. Can you give me tips on what I can still do. Except to drive to the factory town. Thanks alex
