Hi there,
Want to dig out this thread a bit.

Setup:
1.8L transverse engine
with longtitudal engine ECU 8E0 909 518aq
K04-064 turbo from s3 8P with cold side from k03 from AXX 2.0L tfsi engine. eDV built in.

Thing is:

When stationary, reving to arround 3200rpm causes turbo surge noise. Same thing when driving. Only above certain rpms (3200) or? certain boost eDV drops pressure as it should.
Readed whole thread and didn't know how from what i should start testing,  I will try golfputtputt solution and post some results (if i gather some).

Is there anyone who succesfully made fully correct working sollution for this?
