Been dealing with the p2261 ECU code for a few weeks now and about at my whits end. Car is a 2011 stock 2.0T . Ive check the bypass valve vacuum hoses and hoses leading to the turbo for leaks and all came back clean. The bypass valve diaphragm is in perfect shape and doesn't seem to have any oil in the chamber. I eventually took my car into the shop to have it diagnosed and they comeback with the wastegate solenoid is throwing up the code. Bought a new one and put that in which got rid of the light however I'm still getting terrible acceleration and the awful whining from the intake. Any thoughts???
