Question about 1999 Audi A4

My '99 Audi A4 exterior temperature gauge is malfunctioning. It will read fine for the first 5 minutest the car is on, then it start decreasing very quickly. For instance, it's about 85 Degrees in Chicago right now, and it will start off reading that fine, then it will start declining till it gets all the way to NEGATIVE 50 degrees. This wouldn't bother me other than the fact that after it does that my air conditioning doesn't work.... help...

My 99 Audi A4 resevoir is bubbling, had the water pump and timing replaced a month ago anything????


1. Possible air lock in the cooling system, does the internal fan blow hot air? You can blead the system through small bleeding points on the water hoses.

2. Head gasket gone, do the water pipes to the rad expand under pressure?

3. Faulty thermostat. Thermostat controls the amount of water directed to the rad.

4. Not enough anti freeze.

5. Rad cooling fan not starting when supposed to causing overheating. Does the tempture gauge in the dash read normal.
Let me know how it goes.

Troubleshooting a/c


Checking the pressure with the system not working won't tell you anything. A system with just a half pound of freon will read outside air temp on both gauges with the compressor off.
I guess my first few questions would be - - is the compressor running at idle, what are the gauge readings at idle, and is the cooling fan running at idle ?
The two gauge readings at idle with the compressor running should be 30-45 low and 200-250 high.

Audi a4 1.9 tdi 2006 coolant error


You need to diagnose to find out what is CAUSING the coolant error. I cannot tell you what is causing it without diagnosis being performed and although many uneducated peope may try to "guess", neither can they tell you for with any certainty. Diagnosis begins with many questions that must be answered:

> Is the engine running too hot?
> Is the engine running too cold?
> Is there a malfunction in the engine coolant temperature sensor circuits?
> Is the data from the sensor within its designed parameters?
> Is the sensor providing the correct temperature reading to the computer? Or if not, is the reading too high or too low?
> Is the thermostat opening at the correct temperature?
> Etc. Etc..

These gauges have switches that work by earthing, ie, if you take wire off at sensor end & touch any metal surface on your engine with the wire end the gauge will rise to maximum, it may be the wires are earthing out someplace. There is a voltage stabilizer on back of your dash that maty be going faulty?
Hope this helps.

My temperature gauge warning light is coming on periodically...oil level is fine. What should the temperature be at? Is it possibly a sensor problem?


The temperature guage measures the coolant temperature, not the oil temperature -- the normal range is indicated on the guage.

Check your coolant.

Heater does not produce hot air even on high only warm air


My 2002 Audi A4 doesn't produce the hot air, It's an Auto computer control temperature system. I took my car to the local mechanic (gas station), he said that the water pump and the timing belt need to be replaced.

The heating system normally produces by the engine, then normally the "thermostat' is causing the issue, but the temperature gauge doesn't indicate the overheat.

Any idea what's cause this problem?

How do I locate the sensor on a 2003 A4 1.8L? I see a blue sensor on the right by the firewall, and a green sensor on the left nearer to the battery on the left. Is it possible that I already have a green sensor in my car?

I just had the same problem and read on another post how to fix it. Unlock your car, open and close all the doors, and lock it manually with your key. It worked.
