Re: audi a4 whooshing noise
1.8Ts do not have a BOV. Instead they have a 710x recirculator valve that does
not vent to the atmosphere.

Re: audi a4 whooshing noise
Check around the drivers seat. Right side, or left side, I forget. It is
used to pull cash out of your pocket. Keeps you broke.
Sorry, could not pass it up.

Re: audi a4 whooshing noise
Well, I had a similar experience: hissing/vacuum-like noise, and some
loss of power. If you're in the same boat, then if you read out your ECU
codes, you will see:
17965 - Charge Pressure Control: Positive Deviation
P1557 - 35-00 - -
(note, this does not set the CEL)
Cause for me was a split "vacuum" hose (but sometimes vacuum hoses are
under pressure in these cars. The leak was near where the vacuum lines T
off that feed the N75 boost regulation valve. This causes the boost
pressure to spike. Once that happens, the ECU limits max boost to ~4psi
to ensure no overboost is generated. That results in the crappy power
output.
For my split hose, at idle (when the "vacuum" system really is under
vacuum), just look around a bit. My hose was split so badly it had
collapsed, and hissing noises were pretty evident.
Good luck,
Arthur
