I'd say it's the torch!



(I kid, I kid... us Yanks call it a flashlight.)



Sure it wasn't a brake pad/caliper stuck? You can usually walk around the car and get an idea- or the wheel/hub will get warm

I had simiar problem, with an electrical burning smell and it was the radiator cooling fan, apparently it's quite common according to mechanic. took 3 weeks to get part in as it was on back order or something.

Dirty caliper pin, calipers not releasing.

How hot did it get?

Personally I would now replace the caliper, both front pads, rotor on siezed side, probably the pair. Flush brake fluid.

Take me 2 hrs.

You could just take you caliper off, clean up all the crud, lubricate everything... check pads and rotors for wear. Bleed.

Once the rotor/caliper overheats I get concerned with the seals...

Burning plastic smell

Guys, I had the same problem. It was just last week when I started smelling plastic burning after driving my X3 around. First I thought it was the disc brakes (brake pads) but normally you would hear the grinding sound when you brake. Second theory was I thought it was something to do with the heater or internal engine issue.

Well, yesterday I googled what other things that could have caused this smell..."PLASTIC BAG". How ridiculous does it sound. Surprisingly enough, I went to check under my car and saw a black hardened plastic stuck on the exhaust pipe.

I pulled most of it off, but there are still bits and pieces stuck on the actually piping itself. So yep, just FYI...and yes it surely can happen. Everytime you see a plastic bag (that's been littered by a fool) on the road while you're driving...make sure to look in your rear view mirror to see that it is still wondering in the air. If you don't see it in your rear view mirror...damn it, pull over and check under car, pull off the bag...before you really do get some plastic toxin in your lungs!
