They don't make it easy do they :) The cooling fins also present an issue as presumably a large amount of the underside wants to be in free air for them to be able to work?
Morning Ian,

I’m going to test how hot the fins get during the week. I’ll run my phone down and leave it on charge for a couple of hours (with the battery charger connected)

I’m really hoping that it doesn’t get too warm. This factory QI Wireless Charging Module would never be running at full capacity in an A2 as the Module also enables wireless connectivity to the later style MMI for music streaming and screen mirroring/sharing on recent models along with a couple of other functions. I’ll only be demanding the charging function.

To try and replicate a car interior on the hottest day I’ll wait for a sunny day and set up the test rig again. This will be set up on the kitchen floor next to the bifolds which get hot all day (south facing).

I’ll move to the installation stage once I’m happy that the temperature doesn’t get dangerously warm. I am very confident it shouldn’t as Audi must already looked into this and it’s the main reason why I wanted to get for a factory item.

The potential problems are not worth considering should I have taken the aftermarket approach. One of the reasons I have keep everything as OEM+ as possible is knowing that an amount of testing has happened in the background. This should also not have any interference with radio reception which usually happens with aftermarket items.

Waffled on long enough for now. I should have a couple of Twist items delivered this coming week to play with and will keep everyone updated with the progress.

Kind regards,

Tom

Afternoon all,

Well I have completed the testing today of seeing how hot the Audi QI Wireless Charger gets whilst its in action. Its looking very good indeed!

This morning I set up my rudimentary test rig again, this time on the floor next to the biflods that are south facing and have had sun on them for the last 4 hours. My iPhone was run down to 10% battery life and placed on charge. Its taken all 4 hours to fully charge so no where near as fast as having a cable coming from it. I'm happy with this though as I really want a cable free environment.

Test rig set up as explained:

6F9DD39D-34F4-4534-BC84-BA407379480B.jpeg


The temperature of the cooling fins on the bottom never got above 38 degrees celsius. Some of this heat could well have been from the battery itself as I had it connected to an Oxford Battery Optimiser throughout along with it also being sat in the sun. This 38 degrees is no worse that a RNS-E on a hot day (or cold day with the heater on) with all the harnesses stuffed in behind it.

Temperature settled below 38 and didn’t rise any more:

2972FC88-5626-4F1D-9EA1-C09C8A93294E.jpeg


As primitive as this test was, Im happy with the results and prepared to take it to the next level and get ready to site the module for constant use.

I have measured the gap below the transmission tunnel trim and there is actually plenty of room above the Airbag Control Module. The QI Wireless Charger is only 28mm deep/thick so I have no issue as it leave some 30/40mm free air.

The Wireless Charger will sit nicely inside the 4 recesses where the retaining clips go, winner!:

E916CF8E-8874-4945-82E6-BF12040C7241.jpeg


The depth to the Airbag Control Module is over 60mm:

C7EF6616-B4B9-4DB6-8F8C-425C3AAB4EBA.jpeg


I guess the Dremel will be employed in the next few days to have this handy little upgrade fully installed where I first wanted it.

It'll be daunting attacking the Twist Centre Stowage Tray but needs must and I really want my phone on charge down there out of view whilst driving.

Looks like what I first set out to do will be in place by the weekend, work permitting of course. Quite happy with the outcome of this.

Kind regards,

Tom

Thank you for the encouragement and kind words Sir.

I’m absolutely over the moon the way this is looking to turn out. Just got to find my packet of brave pills before I proceed, think they’re in the Dremel satchel!

The old rule of thumb. Measure at least twice & cut once, best of luck, looks spot on.

Thank you Stan,

This is exactly the flow I’ll follow. Pictures hopefully at the weekend once I’ve had time to complete the work. I still need to do the front bumper swap also.

There is always something on the list of things to do here.

Evening all,

Working from home again today so in between meetings I managed to have time to get the Torx Bits out.

Most of you may have noticed the passenger centre tunnel panels had holes in from a bracket that a previous owner fitted:

A86368C6-0E74-4EBA-8E38-B32B9322FB3B.jpeg


I’ve been waiting to replace them since last March. Luckily @A2Steve finally had a breaker in with Twist interior. Of course I jumped at the opportunity to swap over the above panels for something a little better (thank you Steve):

7E5C6542-20B4-4E90-8F8E-A1637D59E6A3.jpeg


Much better I’m sure you’ll agree.

Whilst I was in the A2 I thought I’d fit the Centre Stowage Tray after attacking it with the Dremel over the weekend. Before I could fit said tray I have to remove some of the transmission tunnel trim below the handbrake:

4596CB8D-D154-4FF1-82EA-8A3F2ECBF2C0.jpeg


After removing the Twist trim inside the red rectangular shape above; the tray with the integrated QI Charger dropped in and fitted perfectly, plenty of clearance above the Airbag Control Module:

FBCFD577-6844-473F-9ECF-057852E0836A.jpeg


The charging module sits flush and works perfectly. Very happy with the resolute.

Kind regards,

Tom, does the phone fit in the tray whilst allowing the handbrake to release?

Ian
Evening Ian,

Yes it does Sir, the charger is flush with the original bottom of the handbrake tray; which has been removed.

Specifics: I have an iPhone XR with a (rubber/soft plastic bumper with clear plastic rear) case along with a glass screen protector and there is no interference of the handbrake lever being lowered.

I couldn't get a picture of it to show this earlier as its my iPhone that i use as the camera. I'll get the wife's phone in the morning to show the clearance with the iPhone on the tray and handbrake lever lowered.

Kind regards,

Tom

Thanks for the info. Adams Pixel 3 XL interferes with the handbrake, so the base of the tray would need to be lowered to make this work. I believe the iPhone XR is a fair bit smaller.

Hi Ian,

Lowering the QI Module should be easy enough.

There is quite a bit of room below the trim that I cut away. Some 68mm when I measured it (as shown in an earlier picture), then there is the height of the tray above that tunnel trim which is roughly 15mm making a void of 83mm above the Airbag Module. The QI Module is only 28mm deep so you have a 'spare' 55mm to play with for a phone of larger dimensions to that of my iPhone.

Its a fairly quick thing to install and I really am happy with the results.

I no longer have any cables for Handsfree calling, streaming to the AMI and now charging!
Kind regards,

Tom

Well done for having the bravery to persevere with this one Tom :) I did wonder if it was going to work, but there was more room under the tunnel than I gave it credit for. That's a really good looking modification that integrates the A2 interior even more nicely with the modern age 👍

Evening Ian,

When both you and Tom said there could be issues with Airbag Module clearance I was nervous and did wander if this would actually work out. You know me though, a stubborn meddler who will just keep trying.

Before I got the measurements involved, I did consider raising the height of the trays floor but noticed this would cause the issue that Ian @Kleynie mentions above.

All has worked out very nicely and I really am thrilled the way it fits, looks and most importantly - functions.

Kind regards,

Tom

Hey Tom! First of all what a great project! I also love to modify my car ( Seat Exeo ) but only with retrofits mostly of the items that were available in the higher specs A4's. Recently I have retrofitted latest Seat RNS-E in my car and I was able to get pretty much everything going including SDS, Bluetooth, USB interface ( not AMI ) and I accidentally bumped to your image with the OPC being displayed on the RNSE. I really like the idea and I would want to implement this in my car as I have rear parking sensors. I have seen the page with the custom firmware, however I am a bit lost when to comes to gathering the bits and pieces to have this installed.

Following this https://rnse.pcbbc.co.uk/arduino.php I believe I will be going with RFSL/V-Signal Injector with Rear OPS Support (8Z0) which I believe was in your case.

I have currently got:
- Exeo RNSE ( like you )
- I have parking
module that is currently installed 3r0-919-475 however I have seen that the recommended is 8P0-919-475 which I believe is the same but I am not 100% sure
- I have Arduino UNO

I can see that the only thing I am missing is STMicroelectronics E-L9637D IC

Now I am wondering how did you connect this lot. Would you happen to have a picture of your Arduino board ?

Do I also require MCP2515 EF02037 shield?

Any help greatly appreciated!

On a side note I have also bumped into the R8 RNSE retrofit can be fitted with a reversing cam and also OPC

They do not say what module is going to be needed but I know the guiding lines would require the CAN to work but I would not be interested in that, just the OPC and the Camera would be just the world.

Afternoon and welcome to the A2OC,

Thank you for your kind words regards Project OEM. It is my daily commuter, come obsession to retrofit as much OEM+ items as possible whilst on a budget.

I can answer all your questions and can go into more detail later on as I’m busy right now with Top Dad duties.

The Arduino UNO, CANBUS Shield and K-Line injector are required even if you only require the K-Lone Diagnostics for the OPS display on your RNS-E PU. I’ll get pictures of it added later on. If you have the 3R0 035 192 RNE-E then you won’t require RVSL and V-Signal injects from the Arduino UNO as your head unit already does this, there may be a need to play with the coding though but more than happy to work with you on this.

I’ll have to do some investigation regards you PDC Control Module to see what’s possible, Stuart on the PCBBC RNSE website will be the person I get these answers from as this really is his area of expertise. Can I ask though, are you wanting both front and rear sensors or just rear. I might already have an Arduino Sketch that will work.

From the top of my head there is a requirement for a a separate module to get the Rear View Camera display on the RNS-E and I haven’t dont any research on this so far. What I do known is that you’ll only be able to get 1 feed on the RNS-E when you select reverse, you’ll have either the OPS Sensor page or the Rev Camera displayed.

It might be worth starting your own thread about your on going RNS-E project as I’m sure it will be of use to us ‘A2ers’. If that’s not something you’d like to do I’m more than holy to assist over PM.

Kind regards,

Tom

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
