Any Update on this?

took it to one shop last week and they couldn't figure it out. I have an appointment tomorrow at a different shop a euro specialist and they will do some diagnostics will update whenever they find something most likely they will tell me next week since they close on weekends

I'm wondering if resetting it would of "solved" the problem. It sounds like it could of been an electrical gremlin. And it wouldn't have come back

forgot to mention I've taken it to a total of 3 different shops including the one it's at now
1st shop they were able to reset it however it came back on on the way home about 10 miles
2nd shop couldn't figure it out they mentioned it might be electrical but didn't have the right tools to further diagnose the problem
3rd shop where is currently at waiting until Monday for diagnostic
