I've been trying to diagnose my compressor surge and sporadic BOV solenoid working for a few months now and am completely stumped. I have a thread on the non-turbo page since quite frankly I didn't even realize there was a turbo specific page.. if you want to see me slowly pulling my hair out and spending unnecessary money trying to diagnose it see below.

Long story short I have an authentic HKS SSQV BOV (only a month or two old), correctly installed, and am on my second MAC BOV solenoid, with new vacuum lines and the lines are new, not cracked, and are correctly run.
The latest and greatest is it sometimes actuates and sometimes doesn't. For example on my drive home from work today it was working normally (love the PSSSSSSH sound) when I first started driving, then seemingly randomly decided to not work and it's clearly compressor surge, and then about a mile or two it started working again. I absolutely have no clue at this point what the issue is. I'm thinking it may be something electrical in the harness since it is able to work again but I have no clue since it's a new solenoid with a new connection. I'm just at a loss as to what it can be.

I'm legitimately pissed - this one is doing the same thing and I'm back to the code so I either have the worst luck or it's something I'm doing wrong. Do you need to put any sort of lubricant into it or maybe because I have it laid horizontally? I am all out of ideas at this point other than...
