Who knows 5.7 fault code diagnostics?

Well that's a good point, because I had the repair done at the dealer the repair has a 24 month parts and labour warranty, IF I could confirm it was a solenoid i could get it covered but short of removing the intake for inspection I can't varify and if I take to the dealer to check and they don't find a bad vvt solenoid I'm on the hook for the labour. A catch 22 for sure damn it.
