I’m with you John,

It will be a much easier option but I rarely take the easy option. I’d like to see what’s possible with being inventive first with what Audi provided us.

There is also the trim panel below the asthtray to consider but I do think the charging module is a bit big to fit within this area. That said, as it slopes downwards I wander if this could be raised to accommodate it, it’s where most manufacturers have placed their wireless chargers after all.

Decisions decisions.

Kind regards,

Tom
Tom,

It might be a non starter but what about the area on top of the dash you currently have the Audi mat? We know that a void exists there already?

Just a thought.

If you can get a slim QI then perhaps a cup holder could be modified? Keeping within the profile of the cup holder fascia.

Morning Erling,

As Graham has already been said, it’s a bit tight up there but certainly possible.

John point is also valid about the temperature of the phone whilst sat in direct sunlight.

As happy as I am about removing a dashboard it’s not something I was considering for this addition.

Keep the ideas coming though as the more collaboration the better.

Kind regards

Tom
 
Afternoon all,

You’ll remember that I recently fitted a Bovee WMA100 for cable free (Bluetooth) connectivity to the AMI.

Already having installed a Bluetooth Telephone module I really wanted to take the ‘no cable’ theme to charging my iPhone XR. I’ve had this XR over a year and before that I had an iPhone 6S, so not one for changing phones every year, which should see me with this actual phone for a few more years yet. If my next phone isn’t QI Wireless Charging able then I’ll make alterations when the need arises.

Whilst out today (at WOM swapping some seats over for Project 250) my recent ebay purchase arrived:

C461E0A0-14FA-48A7-831F-9D1AB28D4D6E.jpeg


This was from a breakers and I asked them for 2m of loom that I could use to play with whilst I decided on how I’m going to install it. They replied stating that it might not 2m but they see what they can do:

C51C3A46-F174-47FB-A4ED-F02E0C98F35B.jpeg


That should keep me going with more than enough to fit the Auto Dimming Mirror in 250.

The Wireless Charging Module came with the connector and a couple of inches of loom, I quickly set it my test bench (whilst the wife is out) to see if it works:

D262C1E1-662F-4239-8052-169C89BE716E.jpeg


The connector supplied with the module had 5 wires, 2 of which I didn’t need. These are for features that aren’t available in the A2. To get this to work as a wireless charger only was a 3 wire operation:

Pin 1. Terminal 30 - Constant live
Pin 2. Terminal 15 - Switched live
Pin 4 Terminal 31 - Earth

For testing I simply twisted the 2 live wires together and connected it to the positive terminal on the battery.

My iPhone was charging instantly which certainly put a smile on my face.

After recently seeking advice on here, where to place the module it was apparent that the Centre Stowage Tray may not be the best place. Also placing it within a cup holder was mentioned by Graham @audifan which is something I’ll investigate further. I also mentioned the possibility of placing it under the ashtray, which will require a redesign of the trim panel forward roof the gear knob.

Here it is for size.

Centre Stowage Tray:

5CC1EF0D-6123-4FD5-A198-3D5AE331AA14.jpeg


Snug fit which is great but the handbrake doesn’t go down so will need sinking into place.

Under the ashtray:

This looks like a good place to install it but it will require modifying the curved trip panel with a follow up of Twist Volico Paint.

The sensible option will be to pull my finger out and get the A6 (C5) Armrest venture up and running. Another Team work event with Paul @depronman. More to follow on the armrest in the next week or 2.

Whatever option I end up going for, I will (soon) have a completely cable free environment for seamless iPhone integration to the Telephone and AMI Modules all at the same time as keeping the iPhone battery topped up.

Kind regards,

Tom
 
Hi Tom ,having seen the size of the unit in the hand brake tray, I think the cupholder / coin tray would unfortunately be too narrow. How does it compare size wise with the ashtray? If redesigning the trim in front of the gear stick you could build in extra USB, Aux and 12v sockets.
 
Afternoon Graham,

I agree that the charging module would struggle to fit. The module itself is incased within a plastic item and it maybe possible to take to out, this it will be smaller. I will investigate as it is a good idea and its something I'm going to consider.

Yes If I end up going for a redesign of the trim underneath the ashtray I may well add some peripheral connections. The cable free idea might stop me though.

I wouldn't want try to fit it inside the ashtray as I do use it to store small items, mainly a £1 coin so Im not left wanting for a trolley whilst out shopping.

Keep the ideas coming.

Kind regards,

Tom

That fits so well in the handbrake tray, it looks the absolute perfect place, it's such a pity the available depth is lacking there. I wonder if the combination of a few mm gained by cutting out the handbrake tray floor, and a few mm cut from the bottom of the lever shroud, would allow the handbrake to go fully down? Could the wireless unit even live without some of its own underside outer plastic to help it sit over the curved console underneath the handbrake tray?

Have to say it's a lot cheaper and easier to cut the gearknob storage floor though. Modifying a Twist handbrake tray really would be brave-trousers time.

Ian,

I too am a little reluctant to attack the Twist handbrake tray with the Dremel, although it fits brilliantly as looks great. I know there is a bit of room underneath and think it would clear the ABS Control Module. Further investigation required.

I’ll investigate the ‘below the ashtray’ option first (if I can locate the spares at a reasonable cost) but may well come back to the handbrake tray. It would be a shame to damage it and it not really workout in that location. I do think it’s the best looking place though and I actually really want it in there.

Nothing gained by removing any underside plastic. The metal cooling fins drop to the same depth as the exterior trim.:

Decisions decisions!

Kind regards,

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 some 2 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

Keeping pushing those boundaries Tom. Looks great! ??
