I have a 1997 Audi A4 1.8T
And I have these lights on at the dashboard:
Brake
Airbag
ABS
Check Engine

Turn signals dont work even as i changed the flasher relay (emergency lights do work)
also my heater does not work....

I need guidance

Thanks!!!

 

You need to buy a VAGCOM to have an idea really. Brake and ABS is prolly ABS module, airbag is prolly wires under the seat (but even if you fix it you need a VAGCOM). Check engine could be anything, you need a VAGCOM to find out. If you did the relay for the blinkers, I would say check fuses and wiring, otherwise check the turn signal lever at the column. So to sum it up, buy a VAGCOM to start with. If you dont know where search VAGCOM on the forums.

 

I had the same thing happen, heater, turn signals wouldn't work but the flashers did. It's a relay on the firewall. I think I have the paper work at home on which one i replaced. It took about a week to figure out which one. On my 1.8t I had to remove the lower panel and toward the upper left was a row of black relays. try and pull each one and test with a voltmeter. One of those is bad! the other stuff ABS and Check engine use a vag com.

 

if you get 3 beeps when starting the car its a bad abs module for sure im going to redo someones abs this friday

 

Great guys!!!
I appreciate all your input....
I will purchase the Vagcom
