My rad fan has recently been kicking in when the engine is cold as some of you have described. It also continues to run for about 30secs after ignition off even if the engine is only started briefly. I suspected a faulty temp sensor but my temp guage functions normally and anyway i thought the fan operation was determined by the sensor in the middle of the upper rad hose, rather than the one by the engine block/thermostat housing. Marty16610, which sensor did you change to fix your fan problem? Was it tricky/messy to do? How much was the new sensor? Cold-starting has been a big problem for my gal recently. First i changed the battery - no improvement :huh: . Then i changed all the glow plugs (one was open-circuit) but still no improvement! :huh: I now suspect a temp sensor problem because if the ECU thinks the engine is always warm due to a faulty sensor it might command an insufficient fuel volume for cold starting conditions? Anyone knowledgeable about such things care to comment? Anyway, I'm taking it to a local garage later tomorrow for a fault code read-out so hopefully the fault will show up... HH
