New more powerful wireless charger 15W OEM.

Previously, I had retrofitted 5w OEM wireless charger. Not that it was bad, but awfully slow at charging.
viewtopic.php?p=606234#p606234

New updated OEM wireless chargers have arrived with different ratings maximum upto 40W. With arrival of new platforms such as MQBevo, MQB2020, MLB, MEB etc.. VW has correspondingly changed the wireless chargers for these new platforms, ranging from 15W to 40W.
Luckily, few of these updated wireless chargers(15W) still work on MQB platform eg; 5CG 980 611 A and 6VA 035 502. Both of these have air vents with cooling fan, directly controlled by 5F unit, but without mobile signal booster. These are direct swap for 3CG 980 611 unit with same black connector and wiring scheme.
Few newer wireless chargers eg; 3P0 035 502(15w), 57T 980 611(40w), etc are controlled by CAN via GW. These may still work with MQB, but there won't be wireless charging flash message or icon on MIB.

I bought the cheaper chinese 15W 5CG 980 611A from AliExpress. https://a.aliexpress.com/_c4l6fJZb

The more expensive EU version 15W 6VA 035 502, is hard to find used as new is very expensive.
The charging mat for these 15W wireless chargers with active cooling are also different with precut holes in mat for air circulation via vents in charger. The stock mat can also be modified by making holes though. Without corresponding holes in mat, charging doesn't work properly and throws error message on MIB.
I couldn't find the RHD T-roc charging mat for new 15w wireless charger. But I could find LHD T-roc charging mat with precut holes for chinese domestic market.The difference is not noticible and fits ok in RHD storage compartment with little modification.

This error appears when using stock mat without holes with new charger.


To summarise,
- The New 15W wireless charger charges phone significantly faster( 2-3 times) than old 5W charger. During my tests, with 1hr of drive, my OnePlus 12 with 5400mA battery, goes consistently from 20% to 75% charge. So approximately 1% increment every minute with Bluetooth connected and without Android auto.With AA also connected, it's slightly slower to charge. With previous 5W charger, it was very very slow, with 1r drive, charge used to bump from 20% to 40% max.
- The cooling fan starts working when charging starts and goes off when charging stops. It's not loud, barely audible. I am not sure if the cooling fan helps, phone does get moderately warm similar to 5W charger without fan.
- As I said, charging mat is designed slightly different with precut holes for new 15w charger. The air circulation holes are must for proper charging. I tried stock mat without holes with new charger. I constantly got error message on MIB.
I am very much satisfied with the new 15W wireless charger, and I highly recommend it.

PS: If anyone noticed in above pictures, there is another related upgrade done. A >C details will be on another dedicated post.

Another tiny upgrade: New switch for electric tail in driver door.
Even though just for asthetic purposes, the switch now accurately describes it's function.
This switch comes from VW Phideon for chinese market. PN: 3ED 959 835.

Edit: Corrected the new tail switch button part number.

Thanks again for such detailed information about these improvements. Great job!
It's a shame there isn't one of these new chargers for standard MQB with a mobile signal amplifier, well, I'm not an addicted consumer of mobile phone applications, so I'll continue to make do with my current wireless charger.

I love the new button for opening and closing the tailgate. Also, the new USB-C ports.

Maintenance report: Water condensation in my right side headlight.

Rainy season time here. Few weeks back, I noticed a small strip of condensation at the bottom of my right headlight. I thought it was normal and would resolve by itself. Condensation used to reduce during sunny day only to come back again. As time passed, things started getting worse!  now the condensation increased so much so that it almost covered entire headlight dome, severely affecting light throw.
I blame none but myself for not intervening early and letting things worsen due to severe time constraints.



Finally decided to pull out the right headlight and do thorough inspection. Never removed the headlights before nor there was any kind of accident or damage. Pulled out the service manual to see the steps to remove headlights. There are 3 bolts on top which are easily accessible to unscrew, but there is 4th one, under the headlight, securing the headlight to bumper guide ! Sigh ! To access the 4th bolt is a real pain. Radiator grill, wheel arch cover, wheel arch trim and that side bumper has to be dismantled.





Removed the headlight and did the checks. I was horrified by the amount of water condensed and stagnated at the bottom of the headlight housing inside.
Couldn't get the best shot of water inside as I was working at night time.



I removed the water from housing using facial tissues and microfiber cloth. I also had to remove dipped beam led housing to gain access to dome area to wipe off water on it. Unfortunately I forgot to take pictures of the cleaning process.
After thorough cleaning and inspection, I found out the cause. It was the headlight covers rubber seals which were melted significantly.





I was wondering why these seals melted.
May be due to heat generated inside. But my night drives are only quarter of my total drive time. I don't use high beam regularly. Also the drl's are separately located on bumper. Left side headlight is fine, so far not noticed any condensation in it. I was getting the impulse to check the status of cover seals of left headlight, but then, if it's ain't broken, don't fix it !
I temporarily fixed the the covers using 3M double sided tape, filling it in the areas where it was melted. Installed headlight back to factory alignment which I had marked previously using masking tape before removing.



So far the temporary fix is holding well. Condensation hasn't recurred even after driving in rain and few car wash sessions.



I will replace the headlight covers with new ones when I receive them. I will update this post when it's done.

Here is the technical information by VW I found regarding headlight condensation.
