A 3 yr old Xtype 2.0d Classic. ( 27K miles) Great motor, but it takes about 4 miles before the temp gauge registers anything, and even on the motorway the needle moves around in the lower half of the dial. I reason that the sensor might be located in the rad header tank,( unusual) my gauge might be faulty, or more likely my engine coolant thermostat could be stuck half open. Two garages have shrugged it off, saying that diesels always warm up slowly, so it is not unusual. Any words of wisdom from those who should know?
Thanks P
