Went to the dealer today because I have the CEL on, and the car have problems regulating the boost. The dealer reset the ECU and said that the code was there because some inappropriate acceleration (all my cars suffer from these type of acceleration) and the computer just protect itself. But when I take my car I go WOT on 2nd gear and it start spinning the tires (my complete stock Elantra never do that), but then the computer pull the boost and the fun was over. The car feels great for a moment. Tomorrow I will go again to the dealer for a real diagnostic. Can this problem be a faulty boost control solenoid?
