Hello everyone!
I bought second A2 for me as a project. It is with FSI engine and it had some coolant leaks and manifold flaps were cooked from carbon debris.
Coolant leaks are now sorted and manifold flaps cleaned. Problem with manifold flaps are still on going. When I did clean the flaps, they were moving nicely and free. After putting everything back together, starting car and successfully done adaptation via VCDS from group 142 everything seems to OK but not really. Couple throttle revs and I found out that flaps are stuck again. I did undo vacuum hose from actuator and actuator arm is completely stuck.
Any ideas what could be the reason before I will dismantle again?
