Question about 1996 Audi A4

1 Answer

Check engine light goes on even after changing out temp. sensor.

My Audi A4 continually turns the check engine light on. It gives the indication of temp. control sensor. We have replaced this repeatedly. Within a few days, it comes back on. Is this a syndrome with this 1996 vehicle? Any ideas? Thanks.- Mary

    The computer says code 16500-PO116 Engine Coolant Temp Sensor implausible Signal. It always does no matter how many times we change the sensor. Thank you so much. - Mary

    Thanks for trying was because I had not given you enough info. You did the best you could with my vague request. Thank you. I so appreciate your answer! Thanks a million! So grateful, and I will suggest this to my mechanic who is at a total loss of what to do. Being a woman, mechanics is not my thing! Happy Holidays!!!

    Kudos to them! Awesome. Actually I am fairly mechanical which explains why I am on the site. I understand what you are saying, it is logical. I will relay the info. to someone who does the physicallity of it. No title 9 yet, so despite my request for auto shop,and my Dad's cherry picker on the ranch,I was denied. So I build with textiles. It serves me well. I so appreciate your brillance in your field. Thank you for being there with an assist.

The light is comming back on because you have a problem in the emission control system, without the code I can't help you any further, one note it takes the system a couple of days to go through self test before it decides there is a problem, that is why the delay.

    Then code is not the sensor, there are other issues that cause this, like bad pins in the connector, defective connectors at the computer, I did this for 20 years day in and day out, when it comes to these kinds of problems I know my stuff. The THANKS FOR TRYING rating was not very appropriate since I gave you the correct info based on years of experience. Check the above items, that is where the problem lies.

Audi a4 1.9 tdi thermostat diagramm


First time you might check the thermostat operating.

Heed of antifreeze coolant temperature!!!


The thermostat location for a 2000 Audi A4 1.9 TDI is on back of the alternator at the bottom side of the bracket.

IMPORTANT NOTE: It is NOT necessary to replace the alternator if you want to change the thermostat !!!

Thermostat checking:
1. Cold engine. Start up the engine and watch of the water temp indicator. After first value 60 Celsius Degree you still warm up the engine until the lifter (pointer) reach 80 C deg. (second mark after 60 C deg.). At this time you let engine running at idle speed and check with your hand the thermostat plastic housing and hose temperature in bottom left side of the engine. Heed of alternator driving belt and ventilator fan !!!
2. If the thermostat is good the hose must be cold until the water temp indicator reach almost 90 C deg.
3. The thermostat opening temperature is 87 C deg.
4. If the hose is already warm the thermostat is out of order.

Thermostat location, Part number: 044121113, in german - "Kuehlregle" (Price around $25):

Important note: Always replace the thermostat round seal, position 7 in the above picture.

Code P0118 on Audi A4 - Related to Ignition Coil Problem?


Hi, the sensor on the engine (right at the rear end of the cylinder head) has two separate outputs. One drives the temperature gauge and the other provides data for the engine control unit. The output for the engine control unit is almost certainly faulty and the sensor will need to be replaced. It isn't an expensive item and's not time consuming to replace (1/2 hr) - so you could ask Audi to do it for you when they replace the ignition coils.
Hope that helps Matt..

OIL SENSOR LIGHT ON 2001 Audi 2.8liter


It could simply be maybe the person changing your oil never reset the light? or you have a oil pressure sensor leaking or not working.
most of the time its someone never reset the oil change light. even before it goes on it goes by mileage, so maybe it didnt go off yet cause you cnahged it a tad early.so noone even tried to reset it.

I guess you could have an oil pressure problem, but thats going the extreme route.. but if nothing else shows that could be a problem.

Audi A3 2001 radiator fan ruuning all of the time


yeah try to change the sensor.maybe it is busted. normally, most of the late-model cars comes with a fan feature that turns of after 5 or 10 mins even after switching off the engine. this helps to cool down first the engine to reach its desirable temperature before it is totally shut down. its good that your radiator fan has a feature like that. aftermarket perfomance fans do come with that feature because it takes care of the engine state.just try to change the sensor for engine temp

95 grand am radiator fan only runs with AC on


Cooling Fan Temp Sensor is the First thing You Check (with what you have described) Cooling Fan Should ALways come On When The A/C is turned On as A/C Adds A Load to Engine, If Temp Sensor is Faulty it Will Not Give GROUND Signal to ECM >For COOLING FAN >RELAY to Give ground and turn ON The Fan.
There ARE 2 temp Sensors that Serve Different Purposes 1 is for Dash READING GAGE & Or TEMP LIGHT the Other is For ECM or Fan Relay (SAME Thing) you Said>""can disconnect the sensor and fan continues to run" < This Leads me to think you Changed the Wrong One. Not Questioning your Skills Just Here to Help.
TEMP SENSOR FOR 3.1L V6 is Located upper RH rear of engine compartment, near exhaust system. Temp SENSOR for 2.3L Engine is Located in LH rear of engine compartment.
I Hope this Helps Lead you to a NON-OVERHEATING Pontiac.
Good Luck and Have A Great Evening. rejakwilson
