8L MFSW Conversion

What connections did you have the CANBUS decoder join to on the MFSW Module? I have mine coming soon...

I never used a Canbus decoder mate sorry, I’ve got an RNSE so wasn’t necessary.

It’s all in the guide mate, safer you get it from there than me try to explain it and it comes across wrong.
 
on the headunit i have the canbus adapter plugs directly into the main harness of the radio which runs to the iso/din connector of the car, on that harness.

there are a few individual wires that had to be wired up seperately eg for ignition, illumination etc and 2 wires named key 1 and key 2 those connect to the can hi and Can lo of the steering controller, those wires can be connected either way afaik as long as the buttons starts registering on the headunit when u start pressing the keys.

also found this thread if im too vague in my logic

Hmm

I don’t think my steering wheel icons light up...

*thinking face *

Try swapping the data and live cables around, so the pinouts between the steering wheel and slip ring mate. Either that or the module hasn’t got power, which is what Tuffty found.

Had to re thread my mounting holes. One was cross threaded.

And my strange steering lights behaviour

 
Not sure - maybe they're not working because i don't have any RNSE and i have an aftermarket radio?

because in what module is the re-coding done? i can't access radio module anymore.

maybe i need the canbus decoder....
 
just wiring the ground/earth and the live from the 3 pin connector on the wheel will give you button illumination

With an aftermarket head unit I’d say it’s a given that you’re going to need the Canbus emulator.....

Buttons should still light up if it’s wired right though regardless.

- yeah that's what i am thinking too... hmm....

This is the flat one right??? (mine had 6 pins but only has 3 wires in it)

red/purple/brown?

i "re-earthed" the brown wire to join up with the other brown wiring that went to the prongs on the airbags/steering wheel....

Are you on about the 5 pin plug that goes into the slip ring? If so should only have 2 cables in it.....live and data.

Should be terminals 1 and 2 from the connector attached to the wiring for the buttons (terminal 3 is your earth that you’ve spliced into the other earth on the airbag). This goes to the 5 pin slip ring plug, then from the back of the slip ring these 2 connections go to the module as per the photo in the guide.

Yeah that’s what I’m talking about too.

So from the controls there’s that flat plug that houses that 3 aforementioned wires.

Flat plug to the 5 pin housing (which I’ve got two lines), then to the module.

Might have a go at switching the line and data pins at the module ...

Strange that they flicker on at the last second when turning off hahaha

Tease.
 
Either switch them or just bell them out with a multimeter.

Have you put an ignition live to the module?

Check your Canbus connections into the module as well, it’s the Can that controls illumination.
 
Yep.

Fused 10a ignition live to the 75x yellow nut at the relay bus.

12v to one of the red ones. Maybe that’s where I’ve got it wrong
 
I did a bit of a bodge here because I didn’t have rig terminals. Just squashed the wiring in with the other terminals there.

Going to have to get in there to fix it so can have a re visit when I do ring terminals.
 
Just check for voltage on ignition and permanent live cables, check earth is seated properly, check Canbus and check live and data are in the right pins.

If everything’s wired right could be a dodgy module.

Still can’t get mine to work :(

Had a look again this morning and there is continuity and voltage going to all the right places.

Have tried swapping 12v and GND - nothing.
Have tried swapping the LIN and data - I don’t get the flash phenomenon when I do that. Hmmm

This is all still sans canbus translator for an aftermarket radio setup.

And I’m going to change the 10A fuse as ignition wire to a 5A

Other than that I’m stumped lol
 
Did you all join that 3rd brown wire from the steering wheels controls flat black plug to a ground wire at the airbag harness ???
 
Crisis averted. I had a grounding issue.

I had spliced ground from the 3 wires that went from the controls into one of the browns that plug into the airbag.

After some poking around and troubleshooting (mainly noticing that when I had 12v directly hooked up the backlighting worked but once I turned to ignition they turned off - pointing me to thinking “short”) I got it working. How?

Take that ground from the steering wheel flat plug, put a ring terminal on it and attach it direct to the “base” of the steering wheel and not have it associated with the airbag grounds.

While I was searching for a solution I found this.

DSG 8L anyone???

More progress on the bench harness...

CAN gateway module and a wheel module...
Bench lead 001


Using a HEX-CAN lead I can now connect to the wheel module
Bench lead 002


...and code the module should it need it...
Bench lead 003


Harness needs a bit of tidying and all the CAN lines adding where needed... will also wire in the bluetooth module and RNS-E harnesses too... means I can now code all the retro fit modules on the bench :)

It may be possible to retrofit this little lot into the 8L and be able to actually code the RNS-E as an S3 with the correct start up logo..

It is even plausible that it would allow the use of the Mk2 RNS-E without having to downgrade the firmware...

Nice work mate! Look forward to your findings with coding the RNS-E to possible 8L configurations.... the S3 start up logo would be a huge bonus be it a small thing. That and who knows, you might solve this time sync nonsense out this way too

I thought that recoding the rns-e as a6 is so it uses the same speed signal from the 8L as it would in an a6, The newer cars have a different speed signal and it’s not compatible with the 8L, the newer revision led ones don’t even have the pins in the plug anymore.

Did you just need to add the can hi Lo to the obd2 port?

Is that for GALA? as I don't actually use it... its coded out on mine as I find it annoying... especially as I have amps

IanPG said:

Essentially yes... I bought an 8P obd port from ebay knowing the CAN would be pre-pinned... then connected it to the diagnostics of the CAN Gateway module... the CAN convenience of the wheel module is then connected to the gateway...

Not tried it directly yet though... may do that today just to see if it will work...

Sadly though I cannot use my KII-USB lead... seems that the k-line pin is more to allow k-line modules to talk via CAN rather than k-line diagnostics to talk to CAN modules over CAN Gateway

Out of interest... is there a way of getting the 'Nav i' button working as intended and the volume muting as intended?

Not sure if its a wheel module thing or not as the coding list doesn't elude to anything specific...

Currently clicking the volume does the last navigation command as per the early wheels without the separate Nav info button... not sure if it needs a module from a later car or if its a Mk2 RNSE thing

Does anyone know if i would be able to a dual stage airbag to a 8P flat bottom steering wheel?, the steering wheel is supplied with a single stage steering wheel airbag .

The 8P flat bottom steering wheels come with a dual stage airbag as standard. So naturally not a problem, it’s the single stage conversion which is the difficult bit.... what airbag is it that’s been supplied?

Principles will be the same...

Its an 8P wheel module so should be ok... the biggest pinch point on these is the airbag... as you have a single stage then all should be good

<tuffty/>
 
Just done a quick test connecting the wheel module directly to the diagnostic port and there were no comms... tried both power and convenience CAN lines and nada...

Connect convenience back to the gateway and connects straight away...

So... moral of the story is... you will need a hex-can (or equiv CAN) lead and a CAN Gateway module connected to CAN specific modules either on the bench or potentially wired into the car

One issue with the CAN gateway modules seems to be battery drain... the module I have is one thats alleged to do this but as I am using it on the bench then its not an issue...

Part numbers for the later modules that don't have power drain issues appear to be 1K0907530AD or 7N0907530AR... I cannot confirm either way on this of course as I have no experience of them but potentially its possible to wire this little lot in to over come most of the compatibility issues...

At the very least I can now recode relevant modules for retro fitting

Food for thought :)

When did you order urs @IanPG because the gb on fb his where posted from Russia last Friday. So he said he's just waiting on them being delivered. No idea though how long the Russians will take sending them out of customs.
 
yeah it always takes a while from confirmation of tracking to receiving.. for me anyway

My bad, what i meant to say was i have a dual stage 8P steering wheel fitted is there a single stage airbag that would fit this steering wheel, i have everything else working on the steering wheel but as i have a dual stage airbag i get a airbag warning light ( normally only when the outside temprature is below 10c).
