Freightliner Cascadia 2023 SCR Issue

My friend..Is there any chance i can text you so i can tell you more about what's going on ?

 

Seems like i can't text you..
Anyway, situation turned pretty F up..
Tech wrote in one of the estimates ( I received 8 estimates in 5 days, and seems they are robbing me legally ), how harness of rear injector was loose and it's been shaking components around and eventually they struggled to remove bolt which holds Jake Brake Solenoid and O-Ring snapped..So i tried to follow diagram and injector and jake share the same power. So afterwards, they said truck is not ready because whenever they try to run SCR Test and Forced Regen, Jake Brake activates and interrupt the process.. So per estimate, harness and new O-Ring are $186 and diagnostics is 6K ??? WHAT ???
They just keep charging me for diag and unnsucessful attempts to perform the regen..
I was keep asking them how is that even possible, any of this ? Even if it's possible, than it's their mistake if they screwed new harness because Jakes used to work perfectly until i drove unit to the dealership..
