Bad performance in slope

Hi

I have a passat 2000 1.9 tdi 115hp

I replaced my radiator one day. And after i changed it feels like my car has no power.

Sometimes my car drives normally, and suddendly if i drive up a slope it looses all power. I get big torque but no power. If i stop the car and start it again, often the problem is gone, and i can drive normally until i drive up a new slope.

I havn't scanned it for error code. But i will if i cant fix it.

Here is a picture of a look alike engine:

limp mode.. check for boost leaks

hmm ok.
So the car goes into limp mode when i drive in slopes.
But its normal when i drive on flat.

Thanks for the tip.

Took the test.

Code "boost pressure" came up. The mechanic said it was some cables or electric, and he fixed it.
Works fine now
