I have a BMW 2002 330 XI and it overheated after I took it to the dealer I change the thermostat and put water in it but it's still overheated when I drove it for 15 minutes it makes a little quickisound and it throws white smoke I wonder if the engine or the head gasket is blown
The sound increases And the light
went all the way to read I couldn't
stop so I drove from another five
minutes or so
