Cruise control retrofit...

I have a 2019 Startline Caddy and want to retrofit cruise control.
Would I just need to buy the correct indicator stalks and code via VCDS?
I have an MFSW, but without the cruise buttons.
Does the startline model support this? Or is another module required?
Thanks!

Do you have full access to the forum?

In case you don't:
Step 1 - Work out what you need to buy
First of all you will need a compatible Steering Control Module. This is a circuit board in a black casing that sits under your steering column and is what the indicator / wiper stalks, ignition barrel, slip ring and steering angle sensor plug into. Take off the steering column plastic casing (see below on how to do this) and then look under the column and you will see a slim black rectangular part about 12cm x 9cm. Mine had a yellow warning sticker on it (as its all to do with the airbag so dont mees with it unless the battery is disconnected). Write down the part number of the steering control module.
For cruise control you will need a steering control module that is midline or highline. Lots of caddys however were fitted with lowline modules which will need upgrading. To check which version you have refer to this handy table... you will note they are all the same part number... just with a different letter or two letters at the end. The letters tell you which version you have.
http://wiki.ross-tech.com/wiki/index.ph ... l_Versions
My van had 1K0-953-549-AE which is a lowline so I needed a new module.
If you have a midline or highline module already fitted happy days move onto the next bit. If you have lowlline get on ebay and search for the correct part. I was lucky and found a CN module for £13

but you will have to keep your eyes peeled. There are a few versions that will work.
Second if you need to change the steering control module, double check which slip ring you have fitted as it will need to be compatible with the module.
You will see from the link above there are 4 modle numbers for slip rings and these fall into 2 types..
Type 1: 1K0-959-653 and 1K0-959-653-A
Type 2: 1K0-959-653-C and 1K0-959-653-D
Again I was lucky and had a 'C' slip ring which was compatible with the 'CN' module i purchased. If you buy a module that supports midline / highline but supports a type 2 slipring and you have a type one slip ring... obviously you will also need to buy a different slipring. Might seem obvious but thought I'd mention it as its something to check.
Third you will need to find out if you have the diagnostics wire fitted from the steering control module to the ecu. From what I can tell pre 2006 does not have this automatically installed and post 2006 does. The easiest was to check is to look at the plug on the back of the steering control module. Unfortunately this is a bit tricky to see without taking it all apart. See the pictures and guide below for taking it apart but once apart you are looking at pin 13 and whether it has a wire / pin there or not..
If you have a vacant hole then you will need to install this wire (more on this soon). If you are again lucky like me

and the wire is almost there it makes things ALOT easier!
!!warning!! make sure the battery is disconnected BEFORE unplugging the steering control module. Also unplugging this and re fitting it caused a steering fault on my van. I didn't know at the time but I believe this will be cured by a simple reset procedure (not needing vagcom yet) but I didnt actually try this so it MIGHT be that you need a fault cleared by vagcom.
Fourth you need a cruise control stalk. Now depending on if you also need to instal the diagnostic wire or not you can get away with getting just a stalk on its own which can be anything form £25+ or if you need the wire you will have to buy a kit which is about £60 ish. As far as i can tell you cannot buy the diagnostic wire on its own
I actually bought the kit as at the time I thought i needed the diagnostic wire (which is why i now recommend checking if you need the wire first

)
The stalk part number I got is 1K0-054-690-A. I understand this was superseded from 1KO-953-513-A so this may also work if you find one.
As far as I am aware those are all the parts you will need / possibly need in order to retro fit cruise.

I don't have access to the whole forum, so your reply is massively appreciated!
Thanks a lot for writing that up!
Time to do a bit more research and purchases! Guessing most of these parts can be got 2nd hand from eBay?

Yeah you should be able to get it all 2nd hand.
I can send you the full how to if you give me an email address.

On the mk4, the important bit is the correct slip ring, you need the correct steering wheel or stalks, either that or an emulator for the steering controls and some programming, the slip ring is the most important part tho

Hi I have a 2010 pre facelift ex bg caddy maxi and the window wiper stalk is knackered took the wheel off and someone's already damaged the sensor so if I buy a whole unit with Cruise control and the stalks in it will it work before I code the cc in or do I need to code id in straight away

you can buy a MK7 , or Caddy /Sharan/T6 MFSW with CCS , even ACC , and with my module you can make it running with your car ,

Hi guys, i know its been a while since this post was put up but i have a question. Does the mk4 have a seperate steering control module or is it part of the slip ring?? As i cant seem to find it on my mk4. I have a highline slip ring fitted to my van so i bought the stacks with cc on them and tried coding but cant get it to work. Any help would be great guys.

@Scotscad, I'm pretty sure you still need the module and the right steering wheel or slip ring, to match CC versions. Have you read Javitos post at the top and followed the link he posted?

Hi mate yes i did read the post up above. But tbh its all foreign to me. Im just wondering if the mk4 has a seperate scm as i cant seem to see it when i take off the cowling round the column. According to the rosstech guide i have a highline slip ring fitted already. Have tried coding with obdeleven but cant get it to activate and have the exclamation mark next to the cc symbol on the dash.

Sounds like the module is not there, have you done a full scan with vcds to see what modules are fitted, that will show you what's what. If the module doesn't appear then it's missing or was never fitted. If it appears then it could be somewhere else from where you are looking.
Also the stored codes now will tell you what the BCM or ECU thinks is wrong.
If you don't have vcds then you may be peeing in the wind without it mate.
