A couple of times over the last year I've had the turbo suddenly die on me, no error codes or lights and turning the engine off and back on brought it back to life normally so I've not worried about it.
Tonight, it did it twice within 20 mins or so and the second time brought the spanner light on. Again cycling the ignition brought the turbo straight back again however, it noticeably boosted higher than I've seen it boost before hitting 1.2 bar, it usually maxes out at just under 1.1 and doesn't often hit that especially with the air temps we've had today, which also got my panic sensors "twitching" as something was causing it to over-boost.
When we got home, I checked for error codes and pulled off a P0244 code which seems to refer to the wastegate actuator. However a quick search around both on here and on Google seems to suggest it's the charge air bypass valve on the turbo and the boost solenoid on the inlet manifold that cause this problem.
I found a thread by Jezzy (I think) on a Saab forum and one by Dez on here that discussed this, but both threads had several people discussing different things in them so just wanted to double check what other people's experiences are with this and if I'm likely hitting the right parts with those two solenoids.
