Steering Issues - 2013

[rs4dreams]

Background:

They replaced the steering rack with 8K1-423-055-AC steering module along with 18 various nuts and bolts. I'm probably one of few first batch *Canadian* spec cars to have the updated rack as Audi Canada did not automatically authorize steering rack replacement to correct the notichiness issue.

After the steering rack was replaced, I noticed the steering became lighter and the dreaded slipping kicked in.
I unchecked the DSR as per dollardoctor recommended fix, and the steering firmed up a bit but at the expense of the ABS fault code.

Well today, I got the software update and I am happy to report the steering has firmed up, no slipping, and best of all no ABS fault code. Note that fix keeps the DSR checked and activated.

Just want to clarify: are you saying that you were experiencing slipping even with the DSR fix and now it's firmed up? How would you describe the difference between DSR off pre-update and post-update?

to clarify:
1. old rack, steering was fine, no slipping, no notchines.
2. got error message in driver info display that steering was defective.
3. due to error message, audi replaced a new rack, in my experience, steering felt lighter than before, and slipping gradually got more noticeable and worsened.
4. to correct for slipping, I unchecked DSR using vagcom (VCDS), slipping not as noticeable, but steering still felt lighter than the first day I got the car. Got the ABS fault code with DSR checked off which I wasn't happy about.
5. got the official audi steering software update (RVU 48K8) on august 24. noticeable increase in the weight of the steering both in comfort and dynamic mode. DSR is left checked on with this update, which eliminates the ABS fault code.

the new software update from audi appears to have eliminated the slipping while adding a bit of weight in both comfort and dynamic mode. I have tested on both city and highways the last few days for extended drives and confirm it's not just the placebo effect from the first day I got the software update.

Great, thanks for the detailed response. I don't have a new rack yet so my experience may be slightly different.
