Hi, my name is Alonso, I'm a car enthusiast, I've had some VAG in my life and have done some retrofits to my cars and my friends car.
Some months ago I've bought a 2018 Golf Rline Diesel. this unit didn't come with CC, so I decide to buy the MFSW to do the retrofit, have read the instructions in the Wiki Ross Tech page and the following step it couldn't be done by me, so I'm asking for some help with these. I'm attaching the autoscan. Maybe you can tell me what is not working.
The car originally had a MFSW but without the CC buttons.

In your case, the cruise control upgrade (as others upgrade) is only possible with a code provided (and purchased) from Seat dealer

VW group made the retrofit of cruise control on MQB platform cars not as easy as on previous platforms. You will need to pay them for it - essentially buy the official retrofit kit with the stalk-mounted cruise controls and have a dealership activate cruise control with ODIS and a connection to the VW group mothership server.

It has been repeatedly discussed before over the years.

Hi, Well, after taking the car to the dealer, they told me that it was activated but it didn't work. So I started checking everything in the car and have the crazy idea to check how the buttons were working, there is one that says Malfunction (maybe I had bad luck with the buttons and they came broken), so I have the following question, it is possible that coding is giving the malfunction error or I can really have that bad luck. Tomorrow I'll be posting some pictures of the VCDS Screen.

Thanks,

@LONZO :Hi. From your auto-scan, I note that the long-code string for the ECU is like this:

BYTEHEXBINARY
00100000001
11D00011101
20000000000
31200010010
40300000011
50400000100
60100000001
70800001000
83000110000
90000000000

So, I've highlighted Byte 5 because the software switches in Bit 5-6 on this byte tells the ECU to operate Cruise Control - I think (see my caveat below). As you can see, currently Byte 5 =hex04, which means that Bits 5-6 = hex00

Given that you don't have access to the "yellow" long-code helper screens (because you don't have a HEX-NET dongle), I've provided the traditional helper screen for Byte 5 below:
eqVdLGI.png


Note: the picture above is from the ECU on a petrol engine, but I'm assuming that the CC descriptors also apply to your TDI. If I'm correct, then perhaps you might try setting Bit 5 so that Byte 5 =hex24 after the change. It's an easy try - so worth a shot IMO

Thanks, DV52, I'll give it a try and will post results, hope I'll have a green light,

Many thanks,

Partslink24 says:
cruise control system8T0Without cruise control system (CCS)
So You don't have cruise.
YOU CAN'T ADD CRUISE JUST BY BUYING PARTS.
It needs to be activted by dealer. And They need to be sure it got activated. By VW means You need to buy whole VW retrofit kit.

I THINK!!! it is this code for You: 5G1 054 691 A

And once again, licence needs to be transfered to car.


Read here my strory of adding cruise to car with stalk cruise:
