When I bought my car this was my steering original configuration

Address 44: Steering Assist Labels: 5N1-909-144.clb
Part No SW: 5N1 909 144 F HW: 5N1 909 148 D
Component: J500__APA-BS KL.029 0302
Revision: 1AH03223 Serial number: 00071780073601
Coding: 0000258

Being 029 Steering Behavior (Curve) and 0302 the SW version.

I always had this error
1 Fault Found:
01299 - Diagnostic Interface for Data Bus (J533)
008 - Implausible Signal - MIL ON
Freeze Frame:
Fault Status: 11101000
Fault Priority: 4
Fault Frequency: 1
Reset counter: 64
Time Indication: 0

So when I got ODIS the first update I did was the SW, it was in October 2014
Address 44: Steering Assist Labels: 5N1-909-144.clb
Part No SW: 5N1 909 144 F HW: 5N1 909 148 D
Component: J500__APA-BS KL.0 1101
Revision: 1AH03223 Serial number: 00071780073601

The error just disappeared and was so happy. At that time I didn't know it existed Steering Behavior (Curve), so I drove the car for one year like this.

In this link you can see all steering racks, model, curve, Sw, etc

For this exercise we need to know that Tiguan uses APA-BS (not ZF, don't mix) and that my original Curve was 029, checking in the site we will find Tiguan 2008

The curve for Q3 RS is 375, so the target was to put this on Tiguan.

What you need:
  • Tool for flashing, ODIS or VCP
  • Steering SW (from erwin VW) (5N1909144N_1101_BP.sgo and 5N1909144N_1401_BP.sgo)
  • Steering Curve (from erwin AUDI) (v074B3755N1___Lenkung.sgo)

1 - Upgrade to 1101_BP version (if you don't have yet, I had 1101 without BP, so I did this step but don't see any change)

2 - Upgrade to 1401_BP version

3 - I installed Tiguan 2012 Curve because I didn't had AUDI files, why would I have it

4 - I downloaded AUDI files and changed curve to Q3 RS

Done!

PS: I read from Russian foruns that "375" is Q3 RS but I can't confirm that!
