Retrofit Cruise Control on 2008 A5 - which stalk part number?

[lincoln_dj]

Hopefully just a quick one peeps - which part number do I need to look out for to retrofit cruise to my 2008 A5 3.0 tdi coupe?

Using this site (https://audi.7zap.com/en/rdw/audi+a5+s5+coupe+sportback/a5co/2008-620/9/953-953050/) I've determined it should be a 8R0953502D, but the RossTech wiki has me confused, as it lists completely different part numbers...

Cruise Control Retrofitting (8T) - Ross-Tech Wiki

wiki.ross-tech.com

It has the following (relevant) options:
1N3 = Speed-related variable steering assist (Servotronic)
8T0 = Without cruise control system (CCS)
9Q4 = Multi-function display/on-board computer with check control

There are no PR codes beginning 7Y but would assume this also applies:
7Y0 = Without lane change assistant

The article lists the clock spring part numbers. (Module 16 in VCDS) not all springs support cruise so you may have to change your stalks and clock spring.
You can’t mix stalks and clock spring from different manufacturers, they don’t fit. If you have valeo stalks/spring fitted you can replace both with kostal.
