My 2003 started making a loud hard high pitched sound. It changes with rpm and sounds like bearings or metal to metal under pressure. After driving 5 miles it went into Limp Home Mode and started smoking. Restart was still in LHM and smoking, but without noise. Several on/off key cycles got it started with turbo power and smoke, and the harsh noise.
It sounds to me like the turbo is going out. I have searched and found the many LHM articles, with advice to check for air leaks, egr, etc. but none mentioning the noise.
Any advice?
