The "Flash Codes" that you can get from watching the check engine light flash only go up to 99, they are 2 digit codes. Not sure where you got those numbers, because they don't match anything in my CAT programs or books. Try again!

I have the exact same code, but it didn't show up from reading the flashing check engine light. I got it from going through the engine diagnostics system.

I have a C15 at first fault code 92 so I replaced the actuators 1 and 2 and harness. Went for a ride then code 95 and derated. I went back they blew out the ports under the actuators put it back together same code 95. The spill plugs are in place but still same problem. Any ideas
