So, it’s not a hose leaking, now I got the tip to change the oil, because the turbo is running with fresh oil lubrication and it comes to the drop-outs because the viscosity and the abrasion could cause these drop-outs? Besides, if it’s cold no turbo works, as soon as it has the 12° C it is almost problem-free?!?! I really don’t know anymore Sorry, wanted to answer my started topic Turbo drop-outs actually, should not be – now h old again as a new topic Thanks for numerous answers. Greetings Geri
