Something on my car is rattling. I can only hear it when I'm next to something for the sound to reflect off, and it doesn't rattle at idle. This might be difficult to find...

Then again, it's probably just that damn wideband plug bolt that fell out over the weekend. I'm gonna thread lock the shit out of it

Most common cause of rattles on cars now is heat shields, check them first.

Once I had a rattle I couldn't find. It was a wrench that someone lost in the engine bay and I only found it by chance.

My first thought ... especially buzzing sounds.

could be a heatshieldnto

if its auto just power brake it and see if you can isolate it to somewhere in the exhaust

Yep, they slowly work themselves loose or get bent/ cracked all the time.

Tack welding is the cure.

I just add bigger washers and loctite when I refit them, since I don't have any welding gear.

Or, if you let them go for long enough, they eventually fall off. No more rattles!

I kid, I kid. Apparently the heat shield on my Volvo is crucial, in order to prevent heat soak from the turbocharger from cooking the brake fluid in the lines that run just above it on the firewall. Wonder which genius thought of that one...

I recently cut one off my stepdads beater micra because I couldnt be bothered to fix it. That was only for one small bit of the exhaust nowhere near anything else like brake lines and stuff. Strange having the turbo near the brake lines though, mine are attached to the bulkhead and the turbo is between the engine and radiator.

Yeah, Volvo's transverse layout has the exhaust side of the engine facing the rear of the car, so the turbo is low down, close to the firewall. Definitely gets toasty back there. The ABS computer lives in the vicinity, too, and they don't take too kindly to the heat, either.

I notice that renault do the same thing, my mams renault laguna gets a very spongy brake pedal after a long run becausr of the heat. Becomes quite sketchy when towing actually, people reccomend putting in better brake fluid and that somewhat cures it.
