I Changed all my boost hoses to samcos last week and checked the hole system for leakages but coudn't find any. The boost peaks at 1.5 bar and then drops fast to 1bar and starts jumping up and down between 1 and 1.2bar. Does anyone have any suggestions what could be wrong? I looked at s2forum and they said that the wastegate could be leaking. I will check that but is there any other things that could take look at at the same time?

Thanks

Wastegates get blamed when pressure testing but rarely fail. Check the more likely i.e. DV WGFV. Boost peak sounds OK. It usually hits peak 1.4 on overboost WOT dropping to 0.8 at peak revs. My bet is the DV needs renewing.

Changed my DV to a forge one today. The old one had a small hole in the side and now the pressure is stable, dropping when it gets higher revs but doesn't start jumping.
