They are not expert in German. That's the reason I am asking here. Does compression test tells exact issue?
Expert:  Steve replied 1 month ago.

a leakdown test is a leakdown test on any engine. it doesn't matter if its german or not.

no a compression test does not tell the exact issue, a leakdown test will.

I'm sorry is that a question?

Expert:  Steve replied 1 month ago.

You have a blown head gasket, cracked head, or cracked block. If the shop you are at cannot diagnose the issue, you need to take the car somewhere that can.
