2007 E350 Engine Noise
Hi Everyone,
My E350 has about 5k miles and I've recently noticed the engine has gotten louder at idle, regardless of engine temp.
Dealer says it is normal. Has anyone else experienced this?
Thanks in advance.

Might be normal.
Needs more miles in any event.
Many engines are quieter with brand new oil than with older oil, but you should still go 13K miles. The sound at 13K miles--if this is source of the sound--will be by definition, normal.

As the motor wears in, by definition, tolerances are increased. This will usually help improve mileage/power and will often result in a little more sound. I have also noticed that often the exhaust seems to get a little louder.
As an aside, have you made sure the oil level is right? Low oil will certainly cause noise...

In addition, if your VIN is within A708977 – A876088 have the dealer check VMI to see if your vehicle is included in Service Campaign 2006110002 whereas the engine control module software will be updated.

There's a "known" problem with the oil pumps in the 350 and 550 engines. I have a 550 with the problem: noise arises shortly after start-up gets worse over the next 3-4 minutes, gradually resolving as the engine warms. Sounds almost like a dieseling or "marbles in a coffee can" noise. If you think this might fit, let me know and I'll give you more info.

The noise you've described is what I am also hearing, with the only caveat being that, for me, the noise does not subside as the engine warms (i.e., same intensity whether motor is cold or after a 3-hr drive).
I'd really appreciate any info you could provide.
