Before this I had no power loss. Today, after accelerating in 3rd gear to ~3300 revs I heard something and lost almost all power. No smoke coming out the exhaust, no smells, just a loss of power. Turbo noise decreased drastically (maybe even disappeared). On Idle can't rev past 4.2-4.3k, the revs bounce. Has no problem idiling. I have cleaned out the EGR valve 2000 km ago. Could this be a turbo bearing problem?
