e46 gets hotter the faster you drive
new to the site and looking for some advice.
i drive a 2000 320d the 136bhp model. it is not an se and therefore doesnt have a/c.
i previously had problems with the cooling system after i changed the coolant but resolved that problem by eventually bleeding the system properly, however for the past couple of weeks the operating temperature seems to sitting slightly higher than it should. also when driving the car slightly more agresivly (revving up to 3000rpm) the temperature gauge steadily increases as i increase my speed. it does not go into the red but does go very high. if you slow back down to normal cruising speed it will drop back down, after a short period of time, to it being what i think is slightly higher than it should be.
the heater is not blowing any hot air. i was advised to change the heater valve which is done but has not resolved the problem. both hoses leadind to and from the valve are hot. could it be the auxillery heater?? could this have anything to do with my high temperature problem????
