So folks, I’ve done it! I’ve retrofitted the progressive MQB steering rack into the SuperB and it’s awesome!

Original rack: 5Q0 909 144 R

Progressive rack: 3Q0 909 144 L

My 2017 206 came with dynamic steering 2.8 turns to lock and I’ve never loved it. Feels vague on centre and then is not particularly quick to lock. Never felt sporty, even after my coder helped me make the weight heavier using Audi coding/setting.

The new rack was from a 2017 RS3 with the progressive ratio and 2.1 turns to lock. In reality it’s more like 2.0 once installed in the SuperB.

Install:
The mechanic installed it for me today because $@&# that for a joke and also I have no annual leave left. After the physical install by dropping the sub frame, the most painful part was having to drop the glovebox to access the fuse box because the wires lead through the firewall.

Rod ends and boots were all re used from my previous rack.

Coding:
Mechanic ran out of day so I did the VCDS coding tonight in module 44. Old rack coding was 9307. New rack was 91170000. 9307 didn’t work but 93070000 did so I ran with it.

After that I did the G85 steering angle calibration. Took a few goes as I wasn’t holding it still long enough. That cleared the 7 million error lights on the dash except for ACC. A restart cleared ACC error.

The result:
On center it feels much the same as I expected it to but once you get to turns of about 20-30 degrees it’s way sharper/quicker. Feels much sportier now carving corners. The weighting has reverted to the previous stock light weight, even in sport so I will have to go back to my coding wizard for a fresh update to firm it up a little.

Overall very happy and I would recommend it. Cost for the rack was AUD $330 used from a wrecker. Mechanic labour will be maybe 3-4hr.

Good work; nice to see stuff like this bear decent fruit!

I'm considering doing this but wanted to ask were you able to drive the car without it being coded first? Im planning for a mechanic to do the install and could code via obd11 when I got home
