Can turbos give trouble in the Opel Insignia?

Hi Carmel,

Yes, it appears there is. The problem seems to occur with the hose that connects the throttle body to the intercooler. If a split or crack develops in that, it leads to a loss of turbo efficiency and a drop in engine power. The problem can be intermittent or sometimes more pronounced. There also seems to be a more complicated problem with the solenoid that controls the turbo.
