Tom, I have a heated steering wheel in my Macan, so I have some experience of this. I can tell you that having the steering wheel connected to the heated seats is not a good idea. I often turn the wheel heating off after a short time as it gets too hot and makes your hands sweaty, but I would be pretty fed up if I had to turn the seat heating off to do so. Sometimes the wheel heating will only be on for the first 5 minutes on a cold morning, but the seat heating may stay on all day.
On the Macan there is a button on the steering wheel to control the heating, is this not possible in your case?

Ian

I would agree owl heartedly
It’s a bad idea having the wheel and seat heating on a single control
In the winter on the tdi I tend to have the seat on no2 all the time but would not want the wheel on all the time
Either a physical switch the panel next the the asr switch being an obvious choice or a times set to around 5 to 8 mins for the wheel

Evening Ian and Paul,

Thank you for this information, very helpful although it has made it a little more difficult to install. It was never going to be easy though but I think this might just need a bit more knowledge that I have right now. Some more research required I think before I continue the trials.

As you may well know, the A2s Slip Ring only has 7 available pins to utilise.

There is a 5 pin connector and a 2 pin connector.

The 5 pin connect already has 4 pins taken, 2 for the airbag and 2 for the horn.

Both pins in the 2 pin connector are taken for the MFSW buttons.

Therefore only 1 pin available for use. I have pushed 12v through this spare pin and used the already available earth pin and had the cheap aftermarket heat pad working but I do want this to be as close to OEM as possible. Mainly due to wanting to use parts that have been tested by our german friends and not something off the shelf from Amazon/eBay which may fail quickly, cause a serious problem or interfere with radio reception.

During my investigation it seems that the earlier generation A5 MFSW with the Mode button didn't come with a heated option like the latest MFSWs do.

Earlier Buttons never came with heated option for this particular steering wheel/airbag combination:
E2C00530-B290-4191-B56E-F05E69649C93.jpeg

Latest style buttons which do come with an independent heating button:
s-l1600.jpg

s-l1600-2.jpg

Also these later style buttons with the dedicated heated wheel button have ad additional harness which I'm yet to understand what the wires provide, I could probably guess though from the colours but I take nothing for granted:
s-l1600-1.jpg

Above is a slightly different steering wheel but it clearly shows the extra 2 wires in the additional harness. The green sleeved harness with the black connector plugs into the airbag harness and is for the MFSW Infotainment buttons. The red and black connector with yellow and brown wires is the additional harness found in a heated steering wheel which goes directly to the heated wheel button shown in the above pictures. what I don't know yet is where this additional connector plugs into, either the slip ring or integrates into the yellow airbag connector then into the slip ring. If the yellow wire is a switched live and the brown is earth then I could simply use the existing earth within the steering wheel and the yellow wire through the spare pin. Sounds all so easy...

The other issue as already mentioned, these later style buttons aren't compatible with what I have fitted so I cannot simply swap the button arrangement from the right hand side of the wheel with those of the more recent generation. The next avenue to investigate is to possibly solder the heated button switch to the PCB below (where the iNAV button is as its not functional anyway) but that's definitely going beyond my capability of understanding and soldering ability.

As I said, there is not rush for this so more than happy to take my time in getting this right and most importantly; safe.

Kind regards,

Tom
 
Could you link the heated wheel into the rear window heater timer? That switches off after several minutes and would be independent of seat heating. You could manually override the timer by switching it off if too hot to handle.
Graham,

You sir are an absolute legend. Just when I thought it was all getting far to difficult. I think this is the simple answer that has been staring me in the face!

I truly believe this is the best option to investigate; a timed 12v source, brilliant.

As ever you're timing is spot on (as I try to explain to Ian and Paul the hurdles I struggle to get over). This is the vital building block I was after, thank you very much. I knew there was a reason that I should share what I'm trying to accomplish!

Kind regards,

Tom
 
Hi Tom, why don't you repkace your slipring with the part of an Audi A6 of our era. See pictures below for the difference.
There are more connections to be made.

Afternoon Duncan

I’ve never before considered swapping the Slip Ring. Thank you very much for bringing this to light.

There is a similar era A6 in the breakers yard near my work and will see if I can get it cheap and see how many extra pins might be available.

This might just be an answer that Tom @timmus is looking for to see what’s possible for Cruise Control on the later style MFSW with the unused buttons.

Tom have you looked at the A6 Slip Ring yet, if not I’m quite happy to get one to see how many additional pins are available and if it can be accepted into the A2.

Kind regards,

Tom
 
Yeah, I’ve had them in my stocks for some years now. I think I have 5 or 6 in the workshop. ??

Cheers,

Tom
Afternoon Tom and thank you for the information,

I didn’t know you used these for certain retrofits, great to know that the A6 Slip Ring works within an A2 though so thank you again.

Are you able to say how many pins are available for use (total as I know how many are used in a standard set up) as this will assist with my investigation of a heated MFSW. I’m not far off but progress is slow as it’s only the odd 20-30 minutes here and there.

Kind regards,

Other Tom
 
Hi Tom,
Maybe you are already aware of this, but here's i stallation guide of the original A6 MFSW with heating. Most of it similar to our A2, so you can have an insight on how it is connected to the car. Hope this helps.
Morning Duncan,

That is an awesome find from 2006 and an amazing share.

This will help many members in the years to come, this is the sort of generosity/helpfulness that makes this club so so great.

Kind regards,

Tom
 
Afternoon all,

It’s been a while since I added anything to this thread.

Behind the scene Stuart has been working on a slightly different Arduino set up, basically making it smaller by using the Arduino Pro Micro opposed to the Arduino UNO.

I’ll add more pictures in time. It for now here’s a quick image of what will soon be available:

BD1D7336-2D1C-4E66-8782-5925C3F42863.jpeg

It’s much smaller compared to what I currently have.

To make this Pro Micro work the Sketch (text file to make it function) had to be adapted. Whilst Stuart was there making the necessary adjustments he also added the Setting Options to the OPS Display.

Note the Settings option bottom left:
6AB5E0C7-7050-4C42-9B6B-54869137B939.jpeg


Once selected you now get the 2 options below:
3193210B-9114-480D-A472-CA4F3FF73F69.jpeg


The rear volume has 9 options where the actual 8Z0 PDC Control Module only has 5 settings so some volumes are the duplicated:
CB6450D8-95A1-4470-BA24-D3C9BFA492A4.jpeg


Same again with the frequency options, 9 available on the RNS-E but only 5 available via VCDS but it’s still a nice to have feature opposed to it being locked from use:
2BC4FAAD-5DE8-46D0-BF43-954C6311F8FD.jpeg


I may not use it too often but I’m really getting the absolute most out of this RNS-E PU.

There are a few extra little tweaks on the way and I will update you all when the time is right.

I must say that the latest RNS-E custom firmware is just superb, it really has updated our ageing head units.

Kind regards,

Tom

Morning all,

Thought I’d give you an update on the Audi QI Wireless Charger. All good news though.

It’s has been is use for some weeks now and performs perfectly, although only in small journeys.

I’ve recently visited family down in Leighton Buzzard where this latest addition to OEM was used for the whole 90 minute journey there and back. Ive checked underneath and all is good.

It seems that this installation is now proven to work over time which I’m very happy with. Here’s my phone sat on the charger with the ignition on:

Handbrake raised:

iPhone clearly charging:
7E6BD35D-7264-4F6B-B423-DB5F04773E01.jpeg

Cable free iPhone integration is complete!

The interior requires a little cleaning so please do excuse the visible debris. I’ll also repaint the handbrake tray now this is complete as it is really in need of some Volico Twist attention.

Kind regards,

Tom

That is fantastic isn’t it? Like it was designed for that very purpose!!!!

Can’t wait to hear about the next upgrade!

Afternoon Erling,

The next upgrade I’m working on is the Heated MFSW. It’s almost complete and just need to perfect my sewing/stitching skills to get the leather wheel covering back on.

I’ve not been working on this much recently as I’ve got so much on, plus it’s the wrong time of year to worry about it.

In the coming weeks I’ll have all sorted. Testing is complete though and I’m happy to report that I have a timed 12v feed through the Slip Ring to the MFSW. Thank you Graham @audifan.

Another first in an A2 I think which just needs a bit of tidying up and finishing off to look like a factory installation.

There is also another venture/addition that I promised to investigate last year which is well under way. More to follow on a separate thread when the time is right!

Kind regards,

Tom
 
Afternoon all,

Had a rather nice surprise today upgrading the Custom Firmware in OEM from FW290v2 to FW290v3:
Screen Shot 2021-07-21 at 18.23.25.png


The differences the latest Beta FW brings is the option of changing the UK Motorway colours from factory yellow to blue, which is more in keeping with what we’re used to from other satnav platforms. Below is what the Blue Motorway looks like verses the factory Yellow Motorway:

Original
1E00C645-A0C5-4458-AAAA-8CE595F2825A.jpeg


New (custom)
DAF0121A-64CF-4894-9CB2-A945FE44748A.jpeg


You can also use the spreadsheet (also available from rnse.pcbbc.co.uk) to amend any road type to the colour of your choosing. Not tried this yet as I’m happy with just updating the motorways to blue for now.

You can also enable a digital Speedometer within your Full (red) DIS Navigation Compass Display. Picture further down.

If you have Colour DID you can also have this enabled but this feature is already present whilst in navigation mode. The below picture shows both digital speedometers, Yellow is what CDIS comes with, Blue is the new addition (which can be deactivated):

2BDDBE58-7379-44CE-AFFC-82EE2A5E54CC.jpeg


To enable it you simply highlight this new option within the Engineering pages:

68680921-F21F-4353-80BD-F65B788B2F6D.jpeg


Here is the Digital Speedometer enabled on Full (Red) DIS:
BFDE6DAF-AF15-4E7D-B146-AE264A7B4884.jpeg


You’ll notice 0 mph below south facing compass indication. This of course shows the increasing and decreasing speed as you drive.

Yet again Stuart over at the Custom Firmware website has really done some amazing work here in the background.

Kind regards,

Tom
 
Morning all,

Another project has just started here. I’ve recently acquired 2 FBMFSWs with correct buttons and single stage airbag. One will be transplanted into my daily but hopefully with a couple of additions. The other will be kept for spares for a future project.

Also purchased an A6 slip ring (thank you Duncan @DuncanA2 for the advice) for additional pin connectivity.

So what am I hoping to achieve?

Firstly adding the heat pad, connected to the timed rear screen 12v feed (thank you again Graham @audifan) ready for the colder mornings which will be upon us soon enough.

Secondly, as one of the FBMFSW has the paddles, I am hoping to add a pseudo style Cruise Control using said paddles. Similar to what other Tom has accomplished with the Tiptronic Sport Steering Wheel that he recently revealed.

Tom @timmus let me know if you’re already on this type of project and I’ll just wait for you to offer it as it’ll save me hours of tinkering.

Just need to source a few specific connectors and I’ll start to share some pictures. For now here is what should be in OEM in the coming weeks with heating added along with Cruise Control; if time permits:

9B496EA3-546F-406A-8A78-784E908F2ACF.jpeg


I’ll keep you updated as and when I really get into this but excitedly liking the idea of a heated FBMFSW with Cruise at the finger.

Kind regards,

Tom

Yes, I have achieved this. Either paddle sets cruise. Once on cruise, the left-hand paddle slows the car and the right-hand paddle increases speed. Pulling both at the same time cancels cruise.
It is a fun way to operate cruise, but it was done as an experiment for others, not for me. As such, there are currently no A2s on the road with this cruise setup.

Whether or not it can be achieved in tandem with steering wheel heating depends on how you intend to implement the steering wheel heating.
The heated steering wheel arrangements that I’ve done are variable in temperature and thermostatic, but this occupies more contacts through the slip ring.

Cheers,

Tom
 
Evening Tom,

Very happy to hear more about this along with the costs involved. What you achieved as an experiment would work for me. Whilst I’m very happy to take my time and be pioneering (in my own little way), it would be much easier to get someone to do it who actually knows what they’re doing.

Whether or not it can be achieved in tandem with steering wheel heating depends on how you intend to implement the steering wheel heating.
The heated steering wheel arrangements that I’ve done are variable in temperature and thermostatic, but this occupies more contacts through the slip ring.

I have had the heating element working as mentioned earlier in this thread. Used the existing Earth and just a 12v feed. As such, no variable temperature or thermistor cut out. I simply stop the 12v feed once the steering wheel is warmed a couple of minutes after starting the engine. In short I only use 1 additional Pin on top of a MFSW retrofit as per the way I do it.

As such, there are currently no A2s on the road with this cruise setup.

I’m more than happy to be the Guinea Pig here and would be flattered to be the first to have heated flappy paddle CC FBMFSW.

Let me know what sort of funds would be involved as this would be a great addition for winter cruising along the A46.

Kind regards,

Tom
 
Evening all,

Just found a spare 30 minutes so got the solder iron out to fit something i e had on the shelf for a while…

Remember this from an earlier picture:
8F0FEC09-7D61-4904-AE55-1191BA073E3C.jpg


To fit it I had to removed this:
7EA3C5C1-A7B5-4B3E-97F7-8D69595942E9.jpg


And now OEM is a little flatter:
172AE02E-6FCF-4EA7-B572-E35B7D4FF0FC.jpeg


I actually hadn’t realised but this FBMFSW feels a lot thicker than the A1 round MFSW.

Very happy with the results.

Kind regards,

Tom
