I gave fully repaired 2 ADA 4x4's now. Watered and fueled, fitted with pristine parts. And each time, after 5 to 10 minutes, as i'm driving the engine expires with the red icon. All parts remain pristine.
The engine cannot be fixed with a wrench, there's no option. So, unless an Admin is constantly f*cking with me and blowing up my cars, then I come to the conclusion that something about the ADA 4x4 in 1.10 is not right.
