Hello, everyone.

I have problem with my 2.7T, my workshop can't help with this problem. I resolve better issue with power and EGT.
Replacing sensor, new turbos installed, new DV's. Now car have power, but another problem before was really underboosted but now i have 500mbar over... So car is not using now.
And think wastegate in turbos don't work (actuator is new and pipes), car have very strong vaccum so possible some problem with steering valves.

Where i find vaccum valves steering wastegate actuator ? What's number they have, and what's for look behind it, maybe there is problem..
No experience in 2.7T mechanic don't help me, to much valves anywhere :-)

I make one test, disconnect N75... and then boost = 1010mbar, nothing more
connecting.. and always get 1400, 1600. In high rpm even peak to 2430mbar !

Vaccum should be allright, so probably my N75 valve is broken ?

Post a log (ME7Logger).

Please post the original .csv, not an xls or something equally stupid.
