Steering angle sensor reset

Right guys..

I've had this problem for nearly a year now and I want it gone!
Everytime I start the car I get a gazillion beeps, a big flashing red circle in the DIS, ABS/ESP lights on the dash too.

I've tried this from Rosstech Wiki with my downloaded version and eBay cable. Didn't do anything, so Tried my mates version at work. (real, paid for) Still nothing!

ESP Steering Angle Sensor Calibration
Updated  5 Aug. 2011

Ross-Tech is not responsible for any damage or problems that may result from following these instructions. They are to be used at your own risk. As always, you should refer to a Factory Repair Manual for your vehicle!

This procedure details how to perform the zero position calibration for the Steering Angle Sensor (G85) in many VW/Audi vehicles equipped with ESP (Electronic Stability Program). This procedure should be performed when vehicle alignment is performed or if any of the following components have been removed or replaced:

ABS/EDL/ASR/ESP control unit (J104)

Steering Angle Sensor (G85)

Steering Column

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.


Procedure for performing  the zero position calibration for the Steering Angle Sensor (G85) on VW Passat and Audi A4/S4, A6/S6, and A8/S8:

[03 - ABS Brakes]
[Login - 11]
Enter 40168
[Do It!]
[Basic Settings - 04]
Group 001

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.

Click the [Done, Go Back] button and you're all set.

What should I do guys..?

I'm fed up of the beeping and not being able to see anything on the DIS while driving..

Are there any faults stored??

Only the ones relating to the steering angle sensor..

I'll give it a read tomorrow and see if there's anything else, but also to list what they are..


This is all I get..

Anyone..? Anything else gone..? I have no more codes refering to anything like this..

i had this problem once, it was when my rack was changed and while it was out the wheel had been rotated 360 degrees.

go into vagcom and look see what angle your seeing on the laptop when the wheel is straight

Hav you had work done on the steering etc.?

Cheers guys i'll have a look next time i'm on VAGCOM..

It all started when I fitted the cruise control.. I 'may' have dropped the slip-ring!

The fault codes say your module isnt coded to the car, you need to go thru the whole coding procedure before you can calibrate the sensor.

Theres a login code and coding value which needs input before you do those calibration steps:

Full instructions are there.

Doing the angle sensor calibration usually erases that 'incorrectly coded' fault. Strange but true.

Not having much luck with this.

Been through the coding steps, but not sure I've used the correct one. What type are our brakes??

Using my eBay cable I was struggling to get Block 001 to show anything:

Eventually managed to get this, but the GO button wasn't highlighted and I couldn't recalibrate.

Measuring angle, it's something daft like -700!!

Any ideas?

You need to disconnect the column under the dash then Spin the wheel to get it to 0 degrees then reconnect the column

When you see minus 700 degrees turn it left or right to see which way you need to go.

This will cure it

Just for reference I haven't read anything apart from the first and last post so sorry of its a duplicate post

this gets confusing when its split over multiple different posts!

Not better to keep it all in one place?

disconnect column from rack under the dash and rotate the wheel two times clockwise (since you're at -720deg) , reconnect and see what it shows for "straight on".

When you were screwing around with slip ring, you "rotated" is two times off the 0deg position.

The title of the other post was "name the mystery connector". Thought this one would be easier for future reference given it's more relevant to the issue I'm facing now!

Not sure I'm comfortable disconnecting the rack. Not a bolt I want slipping out again!

Will take the wheel off and just spin the sensor round twice before refitting.

Pull the angle sensor off, and very gently turn it all the way counter clockwise until it stops or starts to get slightly tighter - be very gentle with it, the ribbon cable breaks easily.   Then counting the turns,  turn it all the way clockwise until it stops - again be gentle with it.  Half way between these points is the 'straight ahead position'....    Fit the sensor but make sure the road wheels are facing straight ahead.

After this the calibration can be carried out with VCDS.

That's exactly what I did Mike. It was getting tight after about 2 anti-clockwise turns (and about the same with clockwise), so I was fairly sure it was going to be right. The ribbon cable was slightly misshapen though, so replacing it is the ultimate answer. Just want to have working ABS for the xmas drive up to Scotland.

Do it with VCDS connected and the live readout on display, to ensure you actually get it to 0 and save you the hassle of taking it apart again!

The hole in the steering wheel means you don't have a choice where the sensor is (aside from full 360 rotations).

Surely the steps on the Ross-tech site should be setting whatever position the wheel is at to 0?

yeh but the calibration only works when the wheel is streight ahead, and your sensor is telling it its turned two revoutions in some direction.

The sensor only has limited travel so it wont let you calibrate -700 to be zero.

Take the wheel off, use VCDS to make it read as close to 0 as possible, then refit everything and calibrate it and see what happens.

As Julex says, it will be around -720 degrees. 2 rotations should do it. Not sure the ribbon has enough space though!  

two rotations in which direction?

Read my post?

Fiddlesticks... it's fooked!

To make things more difficult, the 0 button doesn't work on my prehistoric laptop. Giving up. Will have to put up with no ABS and take it easy on my favourite driving roads
