I had solenoid issues with the MEG until I became absolutely fastidious about keeping water away from the QD. When I hose it down I do so before I disconnect the O2. I also periodically disassemble the whole thing and clean it with alcohol.
Since I have been doing that I have had no issues with the solenoid sticking and I run my unit manually all the time.......

I can say I have herd about solenoids stuck open on Megs rather a lot. We had two incidents on brand new Megs in our group.
I had always wondered if it had something to do with running the unit manually and not keeping the solenoid active? But thats just a personal theory not a fact.
The units in our group had Shearwater heads on. These have both been replaced with Apex2.
