Pull the cluster and try disconnecting/reconnecting the connectors.

Also scan the car with VAGCOM (assuming CAN connects to the instrument cluster)....

Ill have to give that a try thanks! Its also weird none of my windows will work either

Have you looked at the fuses?

[1sicb6s4]

I checked all the fuses in the fuse box and ecu box and tested them all no luck

[BenSti]

Sounds like CAN is down...

How do you fix CAN

[1sicb6s4]

Do you need VAGCOM to fix it

[cali kid]

The same thing is happening to my s4 right now (flashing brake light/abs driving different). You said you checked your wheel speed sensor? Does that normally fix the problem or should I use this as an example to not do this?

How do you fix CAN

Canbus is a communications network within the car. Most data in the car is communicated over CAN, and most modules will not work if they cannot talk to the rest of the car. If there is a short in the CAN system of the car or if there is the wrong termination at one module, it could cause the entire system to go down. You should have a shop diagnose the Canbus system to identify where the problem is originating.

I checked the wheel speed sensor and it was disconnected I reconnected it and reset the battery and it seemed to cause me all these problems i can't figure it out

[1sicb6s4]

I think that gonna be my next step to bring it to a shop can't understand why plugging in the sensor and resetting the battery caused all these problems maybe something shorted out possibly I appreciate all the help

Do you know if the 04 s4 uses CAN
