Problem Turbine problems


Hi all. This is the first message I am writing, although I have been reading for over 2 years.

I have an A4 1.9 TDI 101 2003. When the water didn't even reach 90 degrees, I stepped on it and after 2700 revolutions it doesn't pull anymore... it doesn't want to at all. After several attempts, I noticed that the only way to pull after these rotations is to stop the engine (does something reset?).

Another problem: this morning when I turned it on, it made a loud ffff noise, which lost its intensity over time. Now it can only be heard when I turn.

Thank you.
