SOURCE: noise under hood like rattling sound

Try checking the heat shields on the exhaust pipe up front under the car. Alot of times they will loosen up, and begin to rattle. You can ither remove them, or try to clamp them.
Hope this helps!

SOURCE: rattling noise when cold start. noise dissapear

You problem is most likely just lifter noise. This is common with a lot of Ford engines with self adjusting lifters. Although lifter noise is bothersome it doesn't pose a serious problem. Unless your engine starts to miss or your gas mileage drops way off lifter noise is just an annoying problem.
I would recommend that you add some Sea Foam Engine Treatment($6-$8) to your oil. This is not an oil treatment it's more of an engine cleaner. If this works you'll need to add it every 2nd or 3rd oil change.
If this doesn't take care of the problem then depending on your engine you may have adjustable rockers that would allow you to remedy the problem. If not, your options are limited to living with it or replacing the lifters and possibly other valve train parts.

SOURCE: loud rattle noise started on

Sounds like the Cat could be bad. Get under the vehicle and hit the cat with your hand. If it rattles then you know what your problem is, if it doesnt rattle then start check the belts and tensioners

What is the cause of rattling noise in the engine compartment? Nothing shows on the dashboard.


Maybe a Tool that was left in the Engine Compartment? A Heat Shield that has come loose?

What were you doing JUST BEFORE the noise started? Did someone work on the car? Have you checked the Oil Level?

Rattle noice engine around the calelitic converter. rattle noice when starting car up when cold. poor gas mileage.


Sounds like you may have a exhaust loose or either the cat converter is stopping up. Some of these have baffles inside which will break loose and cause a rattling noise. When the engine is cold, start the vehicle and crawl under and hold the converter with your hand and even the exhaust to see if any pressure will stop the or alter the noise. Careful it don't take long for the exhaust to heat up. If these baffles are broke inside, it can cause the converter to become stopped up and rattle, this will also give an engine false info when it comes to the fuel and air ratio mixture. Not going to far into it, so i don't confuse you. Good Luck

My Audi A4 2009 makes a rattling noise on cold starts which resolves in less than 30 seconds. Dealer says its an air pump. This doesn't seem correct. The noise comes from the front of the care. Does not...


READ THIS (happy ending so far...):
audi a4 2L turbo quattro, manual transmission with 98,000 KM. Perfect conditions, no oil leaks whatsoever.

Left the car off for two weeks in very cold weather (-10C down to -25C). When I restarted, it started immediately but with heavy rattling noise due to camshaft adjuster not getting enough oil pressure. After 3 minutes of warming up (outside temp.: -12C) at very low rpm (below 2,000rpm), I start moving the car. Still hearing heavy rattle noise. As soon as I pass 2,000 rpm, I get a scary red warning, low oil pressure. Turn off the engine immediately. In 1 minute, I re-start the car and the engine lights check ok, so I drive in first gear super slow (1,200rpm) hearing the same rattling noise. After another minute, finally the noise all the sudden disappears and the car starts running just fine.

Called Audi dealer and they told me that in extreme weather conditions, I should warm the engine for 10-15 minutes if necessary before start moving.
Take away: luckily, I didn't screw up the engine since I was using it at extremely low rpm (easy to do with clutch and manual transmission) until the oil reached full pressure. I am pretty sure now that the problem was leaving the car off for such a long time in freezing weather. All the oil flows back to the bottom, and when I restarted it, the cold oil with high viscosity took a long time to reach all the parts of the engine, specially the camshaft adjusters that are actuated by using oil pressure. Next day, the car started at -9C perfectly without making any noise (as usual). Basically, the longer you leave your audi in cold weather, the longer you might hear the rattling noise until the oil reach full pressure inside the engine. My car took 6 minutes to fix it after couple of weeks in cold weather. This makes sense to me; in fact, in the past I only heard the rattling noise after leaving the car off for a couple of days in the winter.
So far, this has had an happy ending....

Rattle noise when I let go of the accelerator. The faster I go and then slow down, the louder the rattle noise


Have a look at the shrouds around your exhaust system, they are prone to shaking loose and rattle on over run.
Try giving your exhaust a bang ( with your hand when it is cold) and see if it causes the noise . Follow the noise.
Sometimes the baffles fall off inside the muffler and rattle around inside too.
Happy hunting!!

I hear a rattling noise from the engine every time I start my 2006 Murano. The noise will disappear after a couple of minutes.


Quite often after a car has a couple of years on it, a piece sheet-metal, like a cowling, will work loose. The reason it quits is because your car warms up and starts to run smooth. To see what it is, you need to open the hood and then start the car and look and listen under the hood for what is rattling. Carefully push on each thing that you suspect is causing the noise. It will quit or change the noise when you find it. Remember your car is RUNNING and has spinning parts like the Fan Blade and Pulleys and Belts. Its starting to get cold outside so watch any loose clothing you are wearing when you
lean across the engine. If you find what is, shut the engine OFF, and see if it is something you can tighten or maybe replace. It is sometimes a very tedious task finding what's making the noise. Some times it is the engine itself that is the culprit. If you deduce that it is the engine it surely wouldn't hurt to have it looked at by a Pro.

A rattling noise from the engine bay


Check the heat shields on the exhaust system. They get loose from the extreme heat fluctuations work loose and rattle. Especially the one between the engine and firewall where the 02 sensor screws in. It probably rattles less after warm up because heat causes expansion which makes it tighter. Hope this helps.
