Wireless Charger Toster

I have a G30 M550i 2018 ordered with a wireless charger. Since I took possession of this car it has overheated my iPhone X, Samsung S8, Samsung S10 and more importantly the display key fob that came with the car.

I went to my dealer who replaced the unit, didn't help much. The field engineer took a look said that that's how they work and that that's all that could be done.

I call BS, so I did my own research and after 5 months of looking in my spare time, considering outside consultants even considered replacing the unit with an after market unit. I found that an LTE compensator was a part of the OEM installation so I looked at just replacing the battery charger. What I found was no less than 5 hardware updates for the charger so they knew that there was an issue.

When I had the charger replaced with the latest version my problem resolved.

Everyone makes mistakes but how those mistakes are resolved speaks to character and ethics of a person a corporation. BMW dropped the ball on this problem. I was very fortunate to have help from forums like this one and the internet, what if I had a big problem?

So sorry you had to endure this, should have been fixed early by the dealer. I have had no problems with mine, although the phone gets warm, it has never overheated. I was informed of the LTE compensator by BMW, with the paperwork I got with the car. This included the requirement to register it with the FCC, which I did.

Same in the G11 7er, mine sometimes just heats the phone and doesn't charge it other times it's fine.

I had mine replaced in January this year. But I had a similar experience to you where they tried to tell me it's normal, etc despite me sending them a video showing wireless charger acting up. Fortunately for me, I had used the display key in the video. So I insisted that they either fix the wireless charger or replace the key as one has to be faulty. Case ended up at the service manager who apologised for how it's been looked at. It was resolved within few days after they wrote to BMW technical team who advised them to replace the whole unit.

Even if it's fixed, my recommendation would be to not keep your phone in a case when using it. The phone won't dissipate any heat if you do. The case will insulate the phone and make it even hotter.

It's sort of a pain for me, because I have a leather wallet type case, which is worse than the traditional cases people use. There is no way for the heat to escape with the case I have.

Mine is similarly overheating my iPhone X. What exactly should I tell the dealer so that I don't have to go through the same runaround they gave you? That they need to replace the battery charger with the latest version? Do you have a version number or will they automatically replace it with the latest? Thanks for the update on your journey.
