SOURCE: coolant in coolant reservoir did not fill low level in radiator

you must drain air out of system
so when engine is warmed up, just unscrew slightly the thermo time switch which is the highest sensor and unit in cooling system besides the reservoir, until alittle air releases then when antifreeze starts coming out then retighten to specs. BE VERY CAREFUL !!!! LOOSEN VERY SLOWLY AND NOT COMPLETELY REMOVE FOR THIS CAN CAUSE BURNS. MIGHT WANT TO USE A RAG AROUND SENSOR. If this doesnt solve it then make sure you have the correct rad. cap. Also that the filling hose is not clogged as well as the little port on radiator.

SOURCE: Misreading outside temperature sensor on 2001 Audi A4

Ford has the same problem with their sensor, internally short out or come lose check to make sure it is plugged tightly, if it do a quick visual of the wires and make sure no nicks,cuts in the wire, if nothing can be seen to fix replace the sensor.

SOURCE: replacement of coolant temperature sensor

located under intake in water crossover pipe,you can access the sensor by removing intake chamber box,then pcv hose connected to the block,the connector is orangeish 2pin,use a 19mmdeep socket on a 3/8 ratchet to get it loose,make sure engine is cool,also make sure there is a new brass washer with your new sensor,sometimes the old washer comes off when removing the sensor,sometimes it sticks to the pipe,some coolant will escape so make sure to top it off

Where is the engine coolant temperature switch located


Look in area around the top radiator hose on the head/block and the sensor will be square in shape , probably red in colour and have a connection with 2 wires in it.. failing that see the service dealer or a shop that specialises in repairs your vehicle..

try flushing out radiator and then re-fill fresh coolant. If this does not work then there is a possibilty there is a problem with the cylinder head gasket.

1998 Audi a4 quattro 2,8 , is there a fuse for oil gage,my oil temperature allways at 350 deg.


No, there is no fuse.

If the temp is always showing max on the gauge there is a problem in the sensor circuit. This could mean the wiring or the temperature sensor itself.
