Ganyan din unit ko wayback in ’01 kabago-bago amoy pawis ang singaw ng vent! Asked myself, ganito ba talaga pag diesel? Because it was my first diesel ride. What I did is I make it a point to turn off the a/c thermostat on-off switch first for a few minutes before shutting down the fan and engine. Eventually nawala ang amoy panis na pawis na akala ko yung mga mech sa casa hehehe.
