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:

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:

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!:

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

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

Afternoon Erling,

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!

Kind regards,

Tom

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

Thank you Stan,

This is the 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.

Kind regards,

Tom

Yep, that’s the worst bit but at least you’ve now got a spare on route!
