Guys, I'm a little anxious about what might be something wrong. Yesterday while driving the 300SE home I smelled what I thought might be a forest fire—or maybe an overheated clutch...like you might smell from a big, loaded bus with a manual transmission traversing a mountain. Not quite a burning wood smell, but definitely not oil, either. Thought it was outside the car.
Thought nothing of it until I realized, when I got home, that it’s my car. I popped the hood and looked around but can’t see anything. No evidence of a burn. I looked at all the fuses—nothing. However, when I stick my nose into the space between the fuse box and wiring harness, there was a reasonably strong something-burned smell. There was no evidence of smoke. Smells eletrical-ish, but I’m no expert. This morning the smell was mostly gone—but certainly not entirely.
So it’s a mystery. Anyone have any ideas what it could be? The only other visible anomaly I noticed while driving was that the temp gauge was about 10ļC warmer than usual (around 90ļC), and it wasn’t an overly hot day—80ļF.
I had driven the car only a couple of miles to Best Buy and then back.
On a potentially related note (but not likely), in poking around I discovered a weird wire splice coming off the harness; it’s attached to a blue-and-green wire and seems to extend in front of the brake booster and then into another group of wires. However, when I tugged on it a bit, it pulled righto out—and is evidently attached to nothing. I have zero idea whether it’s related to the smell. I assume this has been there for a long time.
I’m afraid to drive the car now because (a) I don’t know what’s causing the burn smell; and (b) this funky wire thing has me concerned as the splice evidently went to another, uh, splice that, as you can see, goes to nothing.
I’m not even remotely qualified as an electrician, so anyone who has a clue and has an opinion or answer is really appreciated. It smells
electrical, but then what do I know.
Any help is much appreciated!
Oh, and happy Father's Day to the dads out there.
