OMG. Good luck with all that bro.

 

Have you cleared them to see if they come back?

 

yeah, cleared them yesterday and they came back today.. while searching around AW, a guy had all of the exact same codes as me (except the coolant temp) but he never got any answers.. so it makes me think it could be 1 small problem causing all these codes

 

Well ya might want to start with the Coolant temp sensor, they can cause some crazy problems.

 

yeah, but i dont think that it would cause emissions problems, unless im missing something

 

Those are a lot of codes lets see if I can help give me your car info please.

 

you ar a 97 a4 1.8 or 2.8

Compare display with specified value for engine coolant temperature sensor (display field 2):
Display Group 1








Start engine and let run at idle.
Temperature value must increase evenly
NOTE:


Temperature is displayed in increments of 1.5 °C.
If engine performance problems occur within certain temperature ranges, and if the temperature values do not increase without interruption, the temperature signal is intermittently interrupted and the sensor must be replaced.
If NOT:


Replace Engine Coolant Temperature (ECT) sensor -G62-.
Press -> button to advance program sequence.
Press buttons -0- and -6- to select "End Output" function 06, and press -Q- button to confirm input.
Switch ignition off.

Checking wiring


Connect VAG 1598/22 test box to ECM harness connector. See: Scan Tool Testing\Scan Tool Connecting and Initial Checks\Connecting VAG 1598/22 Test Box
Disconnect 4-pin connector from ECT sensor -G62-.








Check wiring resistance for open circuit between ECM/test box and 4-pin ECT sensor connector.
Connector terminal 1 to ECM/test box socket 53
Connector terminal 3 to ECM/test box socket 67
Specified value: max. 1.5 Ohms








Check wiring for short circuit between ECM/test box and 4-pin harness connector according to wiring diagram.
Connector terminal 1 to vehicle Ground
Connector terminal 1 to ECM/test box socket 67
Connector terminal 1 to terminal 3
Connector terminal 3 to vehicle Ground
Specified value: Infinity Ohms
Check wiring between ECM and 4-pin harness connector for short circuit to battery B+. Specified value: 0 volts
Connector terminal 1 to vehicle Ground
Connector terminal 3 to vehicle Ground
If wiring is OK:









Check ECT sensor resistance across terminal 1 (signal) and terminal 3 (ground).
Check measured resistance value for appropriate temperature range using graph below (N24-0157).
Range A: 0 to 50 °C
Range B: 50 to 100 °C






Examples:


At 30 °C , ECT sensor resistance should be 1500-2000 Ohms
At 80 °C , ECT sensor resistance should be 275-375 Ohms
If resistance is NOT OK:


Replace Engine Coolant Temperature (ECT) sensor -G62-.
Check readiness code. If Diagnostic Trouble Code (DTC) memory has been erased, or ECM was disconnected, generate new readiness code.
See: Monitors, Trips and/or Drive Cycle (Readiness Codes)\Readiness Code Reading
See: Monitors, Trips and/or Drive Cycle (Readiness Codes)\Readiness Code Generating

 

It actually does a lot.
