SL55/63/65/R230 AMG: New gas tank
"found noise coming from fuel tank. attempted to remove per WIS instructions, found fuel lines leaking to fuel press. regulator mounted on underside of fuel tank inaccessible. necesarry to lower diff. to access and remove fuel lines at regulator. drained and refilled fuel tank to complete repairs. replaced fule tank MI OUT 1942.
quantity- 1
FP number- 230-470-31-01
Description- strap"




My symptoms:
With the top up, radio and ventilation off or turned down, I heard a consistent noise when standing (when driving, the engine/exhaust covered any noise anyway). It wasn't loud and didn't really bother me as I always listen to music and have the top down.
It was a gargling noise (sorry, I can't think of a better description
) that came from the rear, trunk area and thought it was more prevalent on the passenger side. Reading the posts I assumed that it was the much discussed fuel pump/gas tank issue and brought it in for service.
They came back and said it was the amplifier for the stereo, which made absolutely no sense to me as the noise did not resemble anything like a humming sound or white noise. They asked if it's Ok to replace it and I agreed even though I wasn't crazy about the thought of them taking the car apart for what I believed to be a futile effort.
BUT, I just picked up the car yesterday and the noise is gone. Not just less but the total absense of any noise

Hope this helps, at least it might be another source to investigate fi you experience any noise issues...

I also have the sound behind the seat, I wonder if the amp might be the problem
My neighbors audio cuts out the same way in his SL55.
I do think the gas tank is part of the problem because it does not make the sound when the car is on empty only half to full tank.
Who knows?

[B]My audio cuts out once in a while for 10 to 30 seconds and comes back, and this happens with cd or radio.

What you are describing is typical of what happens if I have a message waiting on the cell phone in my SL55. I think what is going on is that the sound from the car stereo system is muted during the time the message "beep" from the phone is being processed. Problem is, the Command system doesn't reproduce the beep; all you get is silence during the "beep" period. If I pick up my cell phone messages, the problem goes away. A friend with a CL600 had the same problem; same fix worked.

I too thought it was the phone with a voicemail but the cutting out happens even when I dont have my phone connected.
Its very odd and happens at various times with no real reason.
Are others having this problem as well?
