The 'No Clues' Diagnostic Nightmare — Car Mechanic Simulator 2021 Walkthrough

Sometimes, clients bring in cars with vague descriptions like 'it just doesn't feel right' or 'weird noise'. These 'no clues' jobs are diagnostic bosses. You'll need to systematically use every diagnostic tool at your disposal: OBD Scanner, Test Path, Compression Tester, Fuel Pressure Tester, and visual inspection. Start with the easiest and most common issues, then move to more complex systems. Listen for sounds, look for leaks, and check all fluid levels. This challenge hones your detective skills and understanding of car systems. Don't be afraid to remove parts to inspect them closely.
