check with :

- all rubber hoses with hose bands to have no leaks;

- be assured that all turbo variable vanes drives smooth to rotate by finger;

- be assured the actuator has good vacuum signal from intake manifold;

- be assured the VSV works properly;

- check with condition of an air filter;

- check with intercooler condition to coo enough of an air;

- be assured after changing fuel filter you have bleeded system;

I have a 2008 Toyota Rav 4 that has only done 42,000 miles. I have recently noticed an unfamiliar hot smell emanating from the rear of the engine and I am concerned that this could be a turbo problem. I have owned the car for over 4 years and have never experienced this smell before. In all other respects the engine appears to be running normally. Any advice on this would be much appreciated
