I have a 2011 Smart W451, and there's a buzzing noise after starting the engine. Here's what's happening: when I start the engine, everything is normal for the first 2 seconds, but after that, a low-frequency buzzing sound begins. The noise seems to come from the rear of the engine, near the inside of the passenger side. There are no fault codes, and everything else like acceleration and speed is smooth with no issues. I recently changed the fuel pump and haven't finished a full tank yet. The noise inside the car seems to be coming from below the passenger seat but slightly forward. I've changed the engine mounts, and the alternator belt looks fine. Has anyone experienced the same issue? Any help would be appreciated.

Do you also hear noise from the engine while inside the car?

Hi everyone, I have a 2016 3.6 Grand Cherokee. Recently, after switching to 0-20 oil, I've noticed a "doo-doo" sound coming from the exhaust area inside the car. It's not very noticeable when I get out of the car, seems like some kind of resonance. Also, after the oil change, the engine sounds louder. I've driven 400 km since then and there's no improvement. Any ideas?

There are knocking noises coming from the chassis, like "gudong gudong" and "gadeng gedeng". I replaced all 4 shock absorbers, but the noise persists. I checked the ball joints and the steering rack, but everything seems fine. Not sure where the noise is coming from in the Peugeot 301.

Chery Arrizo 3, sometimes there's a noise above the glove box. When driving, it usually stops, but after turning off the engine, closing the car door might cause the noise again. There's also a similar sound inside the passenger side B-pillar seatbelt. I want to take apart the dashboard to see if something is loose inside, but I'm not sure where to start. I've previously removed the bumper to install a loudspeaker and added a central control screen with a rearview camera. But I'm not sure how to start with the area above the glove box.

Has anyone else experienced this?
