It can be a sign yes. I'd only say it is once you've exhausted all other options like turbo Solenoids or a leaky intake manifold, or a vac line or two that is old and cracked, or really bad wastegate that hasn't been attempted to be fixed via washers, & turning the actuator screw on the rear turbo. There is a laundry list one should go through before one says the turbos are toast when discussing a 30ff code. |
No, it's a common code that usually accompanies another code. Usually in cases of misfires, boost leaks, etc. or anything that causes the car to go into limp mode.
