Help!, replaced a front bearing and steering column, FAULTS
Hi, I replaced the front drivers side wheel bearing today and replaced the lower steering column.
I now have two issues. The first being when I turn the steering wheel it comes up with HDC fault. The second being that when driving down my track for a test drive, the front drivers side caliper seems to be coming on and the ABS seems to be going haywire.
ANy ideas? I tried to make sure that I did not turn the steering wheel when replacing the lower column, however once disconnected from the shaft, the weight of the wheel re-centered itself... so Im wondering if Im half a turn out.
Is there a way I can check without screwing the clocksprings etc?
I'm wondering if the brake thing could be to do with the wheel speed sensor as I've just remembered I did not remove it when replacing the bearing.
Thanks for your help!

Sounds like the steering out, the steering angle sensor thinks you are already steering so when you turn the brain thinks something is wrong as it has turned too farIID PRO

Steering angle sensor was my first thought too. You will need access to some diagnostic equipment to recalibrate.

Can I not just re adjust the steering wheel?

I have seen the column fitted incorrectly in the past. May be worth checking before delving deeperMy D3 Build Thread

Thanks guys,
Mickey, what would I be looking for?.. how do I tell?
If I turn the wheel from lock to lock and count the turns would that help? would I rick wrecking the clock springs (not exactly sure what they are).

Recent post where the guy used the 4x4 info screen to centre the steering wheel after doing some work
Not sure how much your dealer charges but the I930 tool shows steering wheel sensor angle.

Need to check where the centre point of the rack is, what position the steering wheel is, and how the column has been ffittedMy D3 Build Thread

I'm pretty its the steering wheel being out by 180 degrees.
I turned the wheel about 180 degrees from straight ahead to access one of the bolts, however when I withdrew the upper joint of the steering column, the weight of the steering wheel r-centred itself.... I'm just not sure which way it went.
Can you fubar the wheel speed sensor if you don't remove it when changing a wheel bearing? Im pretty I didn't hit it inadvertently with a hammer when drifting off the old hub?

Can the lower shaft be fit incorrectly?
It seemed to have a notch in it somewhere for the bolt... or it felt like it did when I was trying to re-align it.

This will more than likely be your issue.
In fact, you even answered your own question

OK,
So I think the lower bit is OK, as from memory, the bolt is in the same position as it was before I started the procedure, (and why I needed to turn the wheel in the first place in order to get to it).
My main question is:
If I start messing with the top joint, which means turning the steering wheel by 180 degrees one way and retrying and then trying the other way.... will I risk breaking something in the clock spring mechanism if I'm turning it effectively 180 degrees past its intended limits?
Secondary question, would this be enough to mess with the ABS system, or could this be an issue with the wheel speed sensor.
Im just summoning up the motivation to go back out in the cold, wind and darkness.

You can see which way it needs to go with a diagnostic tool, which is capable of reading the live data of the steering angle

Is the groove in the shaft where the bolt locates continuous around the circumference of the shaft or just a notch out of one side?

SUCCESS!!
Firstly, thanks guys for your help!
The steering wheel was 360 degres out. I suspected it was turning to the right due to it trying to brake that calliper whine going in a straight line, so I undid the bolt, turned it to the left and hey presto... no errors!
The steering feels a lot better and a lot less 'feedback' from bumps through the wheel.
Annoyingly what I thought was a wheel bearing noise, is still there. So Im assuming its either diff, driveshaft or the GG AT's.
Im going with the latter.
...now just to sort out the brake judder and sticking rear brake calliper??...
