Can Steering ECU & Slip Rings be Mixed?

Bummer..

Well as we discussed via PM Mike Im not sure if my cruise retrofit will work with what I have so if it doesnt work then it looks like I'll have to replace the Slipring as well as the ECU, which is gonna be £££ lol.

I've just fitted my cruise this morning with my ECU 1K0 953-549 A and slip ring 1K0-959-653 but I'm yet to program it as I'm waiting for my brothers laptop.. so we'll see if it works or not later tonight... I'm pretty sure it wont though.
 
Sorry mate - senior moment (again!) forgot we have discussed your dilemma before !

Have found a slip ring on ebay if you need one, but post again with your result so far, for the benefit of others.
 
Scrap that, just got it all working :D

Had to scan the car which threw up a few errors in the Steering Wheel Module (16), cleared all errors and double checked the coding and wola.

To confirm:

ECU Module 1K0 953-549 A and slip ring 1K0-959-653 DO accept the Cruise Control Retrofit.
