  | OM 602 turbo, loss of power
  Hi all,  
my G wagen engined by an OM 602 turbo has a strange habit lately     
Whenever the engine reaches the normal temp (82 C) cannot rev more than 2000 - 2200 prm. If I switch off the engine for couple of minutes and switch on the engine runs for sometime normal and after a while starts to rev like to be in an "emergency mode". If the temp of the engine go below 80 C runs normally       
In the beginning I have changed the temp sensors on the engine to eliminate the possibility of a wrong signal either to ECU or to pump.      
I don't know what to do next.  
If anyone could help is very welcomed.  
           
Regards Angelos
