Question about 1998 Audi A4

1 Answer

1998 Audi A4 1.8 On the back of the head there is a sensor which I take to be the temperature sensor. It has a white male multipin plug with a horseshoe clip. There are no wires or female connection for this sensor. Is this sensor needed on all models or is it just an extra? The car is idling badly and stalls when it is warm and sometimes will not start.

If you haven't done any tune-up for a while I would start with new set of plugs after that maybe even new spark plug wire set. It could be sensor for a gauge you may not even have. But you can always call the dealer ask for the service department and describe the part and the location.
Maybe a new fuel filter if you haven't replaced it for thirty thousand miles. Good luck.

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..

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.

1998 audi a4 quatro - where is the coolant part in


CTS is at the back of the engine, behind and below the passenger side cylinder head, beneath the intake pipe going from the mass airflow sensor to the throttle body. It's either black or blue in your car, has four wires coming off the connector plugged into the top of it, and has a retaining clip that holds it as well. Get a new clip when you buy the sensor - they're plastic and break easily.

1998 Audi A4 1.8 - Engine is idling badly and stalls when warm.


Is this sensor at the back of the bulk head under the inlet trucking. Are there two of them next to each other that look the same. If so that could be engine/coolant temperture sensor which would cause all sorts of engine running problems If not pluged into the wiring loom. Need more info for a better diagnoses.
