Hey guys, im sure this a common one, but any help will be appreciated, AMK engine:
For the past few days now my car is suffering from loss of power, in low gears at full throttle there is a loud hissing noise, in high gears at low revs, there is hissing then when i let go of accelerator there is a dumping noise.
I checked vag com and no DTC's, and physically inspected for any split hoses, im thinking if the BOV is letting off steam too early?
only tiny split i found was on the breather pipe under inlet manifold shown in pic, could this be the cause?
Is this a good time to do the bypass?
Any ideas or clues with details will be much appreciated
