If you use one of the Audi forums the codes are almost always the same. I can look tonight when i get home. one word of MAJOR caution here. I reset adaptions on the suspension and I cannot reset the ride height - going to take a trip to the dealer to correct. I don't know if the same will happen in steering, but be cautious.

Ok, I know an Audi R8 code will work as a shop had tried in the past. I just can not seem to find it. Currently steering assist is not working, and I have an error code.

from memory I think 20108 was a common code. It's the same as most of the Audi and Volkswagon models

Just tried it. No luck yet.

Try 20103

This security code worked. 20103. Still trying to figure out why it has a check sum error.

Try 20103

I did some reading on this & I suspect you have a bad module in the steering rack. Some audi's apparently have had challenges, especially if they get water in them or water gets higher up under the car. What I read suggests that you cannot buy the control module separately from the steering rack, however don't trust that, better to check. From what i've read most have had to replace their steering rack and recode the new control module to get it sorted. Any chance you've had something like that occur (either an accident or a high water situation)?

I appreciate you looking into it. The car had some minor damage and I had the bumper and hood replaced. Also the right side control arm ball joint was broken. Not sure if this happened on the tow truck. Everything else on the car works perfectly, just can not get steering assist to turn on. Seems like the module powers up but continues with this error.

 

[rotaryrocket7]

Just based on the lower control arm being broken i'd say there's a chance the steering rack could have been damaged as well. While I can't be sure, i'm going to guess you may need a new steering rack.

Do you know if I can code a used rack with VCDS or would it need to be dealer ODIS system? I can swap out the rack no problem.

 

[rotaryrocket7]

What I've read is that you can recode a used rack yourself with VCDS.

So the car currently has the 4s1423050F steering rack. Seems to be similar to Audi R8 part number.
There are some 4S1423072F, 4S1423072G, N, M available on eBay when searching Huracan. Also some 4S1423050H, D when searching for the R8.
Anyone know if these are interchangeable? They all look the same.

Steering fixed and working perfectly. If anyone comes across this issue in the future. My car had 4s1423050F non-dynamic steering rack. Found a used 4s1423050D just made sure it had the same motor and control module bolted to it which is 4S0909144H. No programming was needed and all warnings and check codes cleared.
