Hi Tom and hello A2OC thank you for the warm welcome.

Thank you for your help so far, you seem like a top bloke!

I am happy to share any knowledge I will acquire while modding my RNSE. So far I did not really take any pictures or shared any information as in what I am modding in my car, but this I think needs to change as I have added quite a bit to my car already over past 2 years I have it, and like you this is a daily so its all on a budget so it will be in reach for most of the people out there who are looking to do the same, well except this bumper thats nowhere to be found that I plan on installing soon.

I am not by any means good at coding or electronics but I am quick to figuring out how to do anything so I am sure I will be sending you a pm with a questions, so I thank you in advance for this.

Coming back to the OPC retrofit as the Camera with OPC is out of the question for the minute as its out of my budget range, but what interested me actually was the OPC and the Camera view simultaneously on the screen form the link I have shared.

I have the 3R0 035 192 and I have currently got just the rear sensors, however as I mentioned will be upgrading the front bumper to the rare one I was thinking maybe retrofitting the front sensors and upgrading the PDC module would be wiser. However for now the rear one will do.

I just went to purchase the Adruino Uno CAN BUS shield with MCP2515 EF2037 with a DB9 connection and also the STMicroelectronics E-L9637D IC, so for now I will probably change over to the RNSE to the custom firmware and wait for the other parts to arrive which will take eternity I am sure. I will keep in touch and as soon as I will have all the required ingredients I will most likely check in with you!

Regards
Bart
Evening Bart,

Please do get in touch once you have everything ready to go. It’s certainly worth also getting in touch with Stuart who runs the rnse.pcbbc website. He may be able to adjust the Arduino Sketch to suite your PDC/OPS Control Module.

The faded OPS Display within the Rear View Camera Display does look rather nice. If this was achievable in the A2 then I wouldn’t be bothered about cost of the Video Control Module, I love it. I’m not sure our generation of Audi Navigation Plus is actually capable of this though. I’d be very happy to be proved wrong though as I see this as something that I MUST have.

I’ll have a chat with some contacts I’ve made regards this later style display when reverse is selected.

Good luck with all that you’re trying to achieve, more than happy to help out where I can.

Kind regards,

Tom

Afternoon all,

I have been in touch with Stuart again to see if I can take, yet again, the RNS-E to the next level. Some of you will have see the links that Bart @bartoo123 has added to this thread recently about his own RNS-E ventures. Amazing what people can retrofit these days.

After a few messages it looks like the set up (Arduino UNO) I already have might just be possible to display the faded OPS image (look at the RHS of the below picture) at the same time as a reverse camera display when reverse is selected. Something like this:
4033E1C6-1AB9-4D55-8308-318C8BD09FFD.jpg

The real test will be to see if the A2 communicates the turning o the wheels over CAN to have something like this:
F366AEAF-42DE-4DE6-BF36-1D9E1D6D8164.jpg

Not convinced that the above curved lines will be something the A2 is capable of but it’s worth seeing what information is sent around the A2s CAN during there type of manoeuvres. This won’t be a cheap feature as the OEM video modules are quite expensive, the things we do (and spend) in the name of innovation!

Heated MFSW?

I’ve also had a breakthrough this morning on getting an additional 12v feed through the slip ring to power a heat pad:
5D31E37C-36CB-43BB-AB0D-DFEFBF590DEC.jpeg


Earth is already present in the steering wheel. It shouldn’t be too long before I attack a spare MFSW and fit a heating pad either side of it. Then of course test my sewing skills trying to get the leather back on just as nicely as Audi intended. I am yet to get an OEM heated wheel element as this is what I’ll end up fitting. Currently only used a cheap carbon heat pad. Just need to figure out which feed to take the power from in the drivers heated seat switch as Ive been using the 12v handbrake socket as the power supply.

I’ll not be installing a separate heated steering wheel button on the MFSW, too difficult for me as it involves playing with PCBs. I’m hoping that the steering wheel can be heated when the drivers seat heating in switched on. It might not work out as I intend and could be a waste of time; but worth a try!

Sorry no pictures as had to pack up tools earlier but all fairly straightforward so far. Hopefully I’ll get time over the weekend to test what signals/voltages are sent from the heated seat switch to the heated seats elements.

From initial (quick) investigation I have found that there is power to the seat at all times (constant live) and that a signal is sent from the heated seat switch to trigger the element to heat up, this might mean that an OEM heating element has 3 feeds:

1. Constant live
2. Earth
3. Trigger from heated seat switch (switched live?).

If this is the case then I may not be able to go any further with an OEM heat pad or the factory heated seat switch as there just isn’t the capacity within the A2s slip ring when a MFSW is fitted.

More to follow in the coming weeks as this isn’t a necessity, thus will take my time over this retrofit. There has to be a way, worst case could be the heated steering wheel element is always on with a switched live feed, not my preferred option though. A bit more testing but I’m close!

Kind regards,

Tom

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?

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

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.

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

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. 👍🏻

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,

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,

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:

Handbrake lowered:

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

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 road colours on the Map display, below is an idea of 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.

You can also enable a digital Speedometer within your Full (red) DIS Navigation Compass Display. Ive not tried this yet due to already having this feature automatically enabled with Colour DIS, hopefully I can get you a picture of it later on as I have upgraded someones RNS-E to this same FW earlier this afternoon. To enable it you simply highlight this new option within the Engineering pages:

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


As promised, 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
