my 335i on fire (blower motor wiring recall?)

backstory: my 335i caught on fire about a week ago most likely (imo) due to the blower motor wiring recall; what's weird is that I had the recall done on this car before, but based on how/where the fire started (with some small differences) it seems that that is still a possibility. from the pictures, you can see that the fire started from the passenger side near the windshield (the firefighters confirmed this), which is where the blower motor is located too; I've contacted bmw and for now they've requested additional photos. I don't want to point any fingers because I'm not 100% certain this is due to the recall, but just wanted to share in case this might help anyone. I'll keep this thread updated, cheers!

( I had this cool video of my car on fire too but I don't think I can attach videos here )

Yikes. Major bummer but like you say, coulda been worse.

Just the other day someone rolled off I-5 in Seattle, on fire, and parked in the first parking lot they could find. A gas station. Then set the gas station on fire. Burnt it to the ground. Yes, people are that stupid.

IIRC there was also a "battery cable" recall years ago where the main + goes into the back of the fuse panel, which is only inches away from the blower motor. I also believe that neither recall properly addressed the cause of the issues:

The blower motor wiring recall replaces the blower speed controller and its input connector and wiring with a waterproof version instead of fixing the persistent water ingress issues. My blower motor wiring melted down a couple weeks ago so I haven't had heat. I pulled the fuse since it kept sparking. I haven't had the recall done yet. My bad. Honestly, I have a job that I need to get to. How am I supposed to get the recall done when they won't give a loaner?

The old battery cable recall had the tech examine, IIRC, the cable and termination and replace if they were brown/burnt. Doesn't fix the issue of poor/corroded interconnection causing a slow overheat and meltdown. Either need more secure connections, stop making things out of flammable plastic, and/or temp sensors on high-current interconnects (this could also help with the blower motor issue)

And before you say "who honestly thinks they would put temp sensors inside high-current interconnects just to monitor for corrosion": Ryobi, known in the USA for cheap DIY-quality cordless drills available only from The Home Desperate, uses a temp sensor in the stem of the battery to monitor the temp of the terminals (in addition to the typical cell temp sensor). Yes, a cheap drill battery has interconnection temp sensing. No reason $50k cars that catch fire shouldn't, especially with its smart, PCB integrated fuse panel.

Also, I can't resist. For Sale: E92, low miles, tasteful performance mods, always garaged, cracked windshield and paint needs some TLC with a clay bar. Tires have tons of life left. Serious offers only; please no low-ball.

Sorry for your loss, it looks like a heavily modded car. I hope that your insurance offers you a decent payout. It may be to your advantage to buy it back and part it out.

That sucks! I'd be interested to see your video though because... I'm a rubber-necker at heart. You can post your video on YouTube and then link it here.
