Try clearing all the fault codes and see if it comes back. What bentley says:
Audi > B5 Platform > 1996 - 2002
1.8 Liter 4-Cyl. 5V Turbo Generic Scan Tool Engine Code(s): AEB, ATW, AWM
24 - Multiport Fuel Injection (MFI)Intake Air Temperature (IAT) sensor, checking Recommended special tools and equipment
VAG 1526 multimeter or VAG 1715 multimeter
VAG 1594 connector test kit
Wiring diagram
Chilling spray (commercially available)
Test requirements
The respective fuses of Motronic Engine Control Module (ECM) -J220- must be OK:
=> Electrical Wiring Diagrams, Troubleshooting & Component Locations
Parking brake must be engaged or else daylight driving lights will be switched on.
Function test
Connect diagnostic tester => page AUDI-B5-FU11-ST-001-03ST-5.
Switch ignition on.
Under address word 33, select "Diagnostic mode 1: Checking measuring values."
Select the measuring value "PID 15: Intake air temperature".
Check specified value of intake air temperature:
PID
Diagnostic text
Specified value:
15:
Intake Air Temperature (IAT)
approx. ambient temperature
If specified value is not obtained:
Continue test according to the following table:
Indicated1)
Cause
Continue testing
approx. -40 ° C
Open circuit or short circuit to B+
=> page AUDI-B5-FU11-24-002-0624-75
approx. 143 ° C
Short circuit to Ground (GND)
=> page AUDI-B5-FU11-24-002-0624-76
1) If a temperature is indicated which is below the ambient temperature of sensor, first check sensor wires for contact resistance. Note that while the vehicle is standing still the sensor might warm up due to radiant heat.
If specified value is obtained:
Remove Intake Air Temperature (IAT) Sensor -G42-. Plug connector back in.
Remember the intake air temperature value.
Spray the sensor with commercially available chilling spray while observing the temperature value. The temperature should decrease.
End diagnosis and switch ignition off.
If the intake air temperature does not drop:
Replace Intake Air Temperature (IAT) sensor -G42-.
Erase DTC memory of Engine Control Module (ECM) => page AUDI-B5-FU11-ST-002-06ST-27.
Generate readiness code => page AUDI-B5-FU11-ST-003-03ST-54.
Continuation of test if indication is approx. -40 ° C:
Disconnect connector -1- from Intake Air Temperature (IAT) Sensor -G42- -2-.
Bridge terminals 1 & 2 of connector using the respective adapter cables while observing the indication on display.
If indication jumps to approx. 143 ° C:
End diagnosis and switch ignition off.
Replace Intake Air Temperature (IAT) sensor -G42-.
Erase DTC memory of Engine Control Module (ECM) => page AUDI-B5-FU11-ST-002-06ST-27.
Generate readiness code => page AUDI-B5-FU11-ST-003-03ST-54.
If indication remains at approx. -40 ° C:
End diagnosis and switch ignition off.
Check wires according to wiring diagram => page AUDI-B5-FU11-24-002-0624-77.

Checking wiring
Connect test box to control module wiring harness => page AUDI-B5-FU11-ST-001-04ST-7
Vehicles with engine code AEB
Check wires between test box and 2-pin connector for open circuit according to wiring diagram.
Terminal 1 & socket 54
Terminal 2 & socket 67
Wire resistance: max: 1.5 ?
Vehicles with engine code ATW, AWM
Check wires between test box and 2-pin connector for open circuit according to wiring diagram.
Terminal 1 & socket 85
Terminal 2 & socket 108
Wire resistance: max: 1.5 ?
Continue for all vehicles
Also check wires for short circuits to each other, to vehicle Ground (GND) and to B+.
Specified value: ? ?
If no wiring faults are found:
Measure resistance at Intake Air Temperature (IAT) Sensor -G42-.
Range A displays resistance values for the temperature range of 0 to 50 ° C, range B displays resistance values for the temperature range of 50 to 100 ° C.
Read-out examples:
30 ° C is in range A and corresponds to a resistance of 1.5 to 2.0 k ?
80 ° C is in range B and corresponds to a resistance of 275 to 375 ?
If specified value is not obtained:
Replace Intake Air Temperature (IAT) sensor (G42).

Generate readiness code => page AUDI-B5-FU11-ST-003-03ST-54.
If no malfunctions are detected in the wires and the resistance values are OK:
Replace Motronic Engine Control Module (ECM) -J220- => page AUDI-B5-FU11-24-004-0324-129.

do you guys think that my car will pass smog check.. I only have the P0112 error left and I need..
it smogged this week.
I cleaned my Oxygen sensor and that seems to have be fine now.. Thanks again everyone for all your help

no but only because i dont think the cel works.. The mechanic down the road has no idea what the..
CEL looks like on these cars he didn't even know what a wastegate was and he told me that my front engine mount the one on my front support was broken. (the one right at the front).
I'm not worried about him, I'm more worried about the smog machine.
I know that I do have to fix the error and the CEL but would really like to get the smog out of the way I had to have it smogged over a month ago

Ok. It will not pass!! so I bought a used instrument panel, installed it and now my car wont start..
I didn't realize that it has an immobilizer built into it. Is there a way around it or do I have to now take it to an audi dealer to get them to code the key with the car with the instrument panel?

THANKS FOR ALL YOUR HELP EVERYONE I REALLY MEAN IT...
Ok finally finished the car today I couldn't do the last error so I took it to a friend of a friend who helped me in 5 minutes. the wire for the thermostat and the AIT were switched anyway all done instrument cluster changed all thats left is the smog tomorrow and then I will enjoy driving the car for a bit.
If there is anything I can do for either of you both Scratchrob and Myers let me know. I fix computers for a living so if there is anything you guys need there I would be more than happy toi help. THANKS a Million
