Rattling noise when accelerating

[Audi3.0btdi]

Hello! I got some strange rattling noise when accelerating. It happens the most between 1200 - 1800 rpms. Anyone have clue what it can be? Thank you!

Hi check the exhaust heat shields and the mountings for the exhaust they are rubber and often fail.

Thank you! I take a video but you must listen closely to hear it: https://youtube.com/shorts/dMms6d1rm...IYxqJgLxzxW6D4

Is it outside or inside of the vehicle?

[Audi3.0btdi]

This is inside the vehicle.

Front, rear or side?

Could it be chain noise?

Hello! 215000km. Also i think i hear the chain on warm engine after 30-40 minutes like small rattling for 1.1-2 seconds. My question is if its chain can i drive more km or it is immediately important to change it? Thank you!

If it is the chain rattling you can continue to drive it if necessary. Of course it will be doing more expensive damage to the engine if you do so, but it will not result in a complete and sudden failure of the engine.

It would help if you answered Steve's question: how many miles or kilometres has the car done.

Odd. I see nothing except a full stop. Can anybody see a response or is there something peculiar about my computer?

Now that I can see thank you. That equates to 133000 miles, so to return to your previous question, yes it could be timing chain. The only way to be certain is to open the chain cover and inspect the chain tension and the condition of the chain tensioner.

Hello again! I go to 2 different mechanics and they told me that this is normal.

[cliffcoggin]

Niso.

Your mechanics can hear the noise; I can not so I really can not help any further.

Note that people often post recordings of what they believe are strange noises, but which are rarely audible to us here. The human ear close to the car can become attuned to such noises and mentally filter out the background engine and road noise. We do not have that advantage so unless you can get a better recording it is doubtful we can do more.

[Audi3.0btdi]

Yes they hear it while driving, they drive it too and said everything is okay. I want to thank you all for helping me and answering my questions. Thank you again!

Hi as Cliff stated we can't hear it, it probably is normal they do rattle but you definitely have only two choices, live with it until it gets louder or go through the expensive process of having it changed now, your choice.
