Replaced new steering wheel. Throwing code: Steering angle sensor. NO horn! VIDEO!

[Audi S4 Turbo]

I made a video, it's easier to see the problem. The horn stopped working also... The bolts are not too tight either, I can still press the horn in, just no more sound.

Thanks in advanced.

Will driving it eventually reset it? Or, do I need to recalibrate it?

[Evilevo]

Are you sure you lined the steering wheel up correctly? Did you unplug the battery before swapping? I replaced mine and didnt have any problems

[Audi S4 Turbo]

Yes. That wasn't the problem. The problem is I turned that piece and it's off calibration or something. The wheel is perfectly straight when I'm driving straight.

[The_Jerbel]

That sucks. Try and put that piece back to where it was before you moved it....

steering angle sensor doesnt need to be calibrated in a b5. as soon as you plug it in it should work fine. sensor is either not plugged in, wrong part or damaged. try swapping sensors with the other one.

Really! I'll remove the air bag and steering wheel and make sure it's plugged in correctly. If I remember correctly, I removed the two bolts behind the steering wheel, then disconnect the plug for the air bag. Then I removed the huge center bolt and off comes the steering wheel. Is there supposed to be 2 plugs?

the plug you should worry about plugs into the back of the SAS. if the SAS Is installed and you are looking at it from the driver seat, It will be in the lower left hand corner BEHIND the SAS. black connector, 6 or 8 pins, unplug/replug, test. with JUST that connector plugged in you shouldn't have an issue. I drove a car yesterday that has the SAS plugged in and zip-tied under the dash with zero issue.. if that doesn't work it's probably a bad sensor.

[damnthemansam]

wow, I just reread your post. how far have you dove into this thing? if all you did was remove the steering wheel and spun the sensor a bunch you probably just ruinEd the sensor. it's pretty involved to get to the connector so I doubt you disconnected that unless you are tearing into the steering column. if it's all out of whack from spinning it someone may come up with some magical way of setting zero position, which I highly doubt, or you broke something in the sensor by pretend driving with no steering wheel..

[Audi S4 Turbo]

I pretty much removed the wheel (which was sideways) and remembered the position. The sensor got knocked and landed at "6 o'clock". So without thinking about it, I spun it back to the correct position so it would fit back into the steering wheel (possibly in the other position?). Hooked everything back up, tightened all the bolts, and turned the car on. Immediately the horn turned on every-time I turned the wheel in either direction. Then after a while the horn shut off leaving the lights on.

Anything else?

did you clear the codes for the abs module? i think that is where they are stored for the car. there is a procedure the recalibrate the system, i had to do it when i replaced my esp controller under the rear seat. The clock spring which your turned has no position, i think it may have stored the new zero value to whatever you may have turned it to in the computer, so you are getting the cel and codes. Do this recalibration:


There are certain test conditions that must be met before doing this procedure:

Start the vehicle.

Turn the steering wheel one turn to the right and one turn to the left.

Drive in a short distance straight line on a level surface at a speed not higher than 20 km/h.

If the steering wheel is straight during the test drive then stop the vehicle with the wheels pointed straight

Ensure that the steering wheel is not moved again.

Keep the engine running and do not switch off the ignition.

This will store the zero (centered) position of the steering wheel. There should be a displayed message that reads: "Steer. angle sender compens OK". If you get an error, it may mean the Login was not successfully performed.

[Audi S4 Turbo]

Thanks! I tried that, and for some reason I can't log into the "basic settings'' entering that code. It was originally coded for "00000" and I typed in "40168" and "go!" and it wont let me log in.

Also, my horn stopped working.

any more input on this? Same issue for me after new steering wheel installation...

[DolphinV8]

PM'd you Justin.

I think this is our problem Justin. We need to recode the ABS, THEN, recalibrate the Angle Sensor. DolphinV8, feel free to jump in because i know you have experience with this.

Turn the steering wheel +/- 10 degrees and then return to the zero (straight) position. Verify results from the screen.
Clear all DTC codes.

That is all I had to do. For me, the ABS light stayed on for a while until I had driven a round for about a mile. Then it was gone. I went back in and cleared any remaining codes. Try this before the steering calibration.

I have done this on both a Tip (L-box) and 6spd (H-box). The codes are based on ESP, not model year.

Here is the procedure for zeroing the steering wheel. Please do not do it unless you are certain it is needed. I imagine that a DTC code will keep popping up of it. You will keep getting the DTC unless you initiate the sensor by turning the wheel back and forth at least 10 degrees. I did not have to do this with my car, so I am going from the Audi instructions, there may be some difference. I don't have my VAG in front of me while writing this.

There should be an "OK" in a block for Calibrating Steer Sens.
Group 005 should display the zero position.
Switch ignition off
Switch ignition on
Repeat.
Clear any DTC's

Remember...I had to go for a drive (a very slow, safe drive for the light to go out). Come back and clear all the DTC's in the ABS module.

[witwer4444]

Tried the directions above again and still no dice. Any ideas?

[Peterjk4]

Looking forward to give this a shot, I was given the task of debugging a family members B5S4 after a steering wheel replacement...so I'll join the conversation.

Witwer, so far it seems like what you provided should work for me. Worst case I have to take everything back apart to make sure everything in connected and working. Will reply by 7pm EST

[PovGRide742]

Honestly... sounds like you broke your clock spring, also referred to as the spiral cable, which is in the assembly of the steering angle spring (the square-ish looking assembly behind the steering wheel). That, or you unplugged it and didn't plug it back in.
