Thankyou for your response. We don't think the ticking is at idle and is only when we accelerate. It is much louder after we have been driving for a while.
The service advisor did say something about them putting silencers(?) on a purging something or other by the frame, etc. We know nothing about cars but it was probably the purge valve like you said. I don't see anything on the work order that says purge valve, he told me this on the phone.
If it is the purge valve, would it get louder after driving for some time? Like you mentioned, it is really annoying especially for a Mercedes that sounds like a diesel when accelerating. Any Suggestions?
Thanks again for your time.

I had the purge valve issue and it was noticeable at almost all times. Sometimes not at all but usually as things warmed up it got more noticeable.
It's a simple fix.

The purge valve is relatively easy to fix and the actual part is cheap (40$). Sound does get louder after driving. It may be more noticable at colder temperatures. It is also posible that the PCV valve (positive crankcase Valve) is at fault. Some people call it also purge control valve, but that is not accurate terminology. Also an easy fix. (in theory you can replase them both yourself). Other things that can make flatter type noise under acceleration, may be loose belts and fans, or leaves or other things that are stuck somewhere. More serious engine things could be maladjusted valves. That is difficult to happen because in these cars valves are auto adjusting. Also do try to use for couple of tanks, gasoline form another Brand name gas-station to make sure they are not selling things they should not. I usually find that AMoco(BP) Ultimate is the smoothest running gasoline, next to Mobil, Hess and Shell.

The outside temperature information actually does interface with the inside temperature control! It uses outside temperature information to decide how much power it should use and if it is going to go into recirculation mode to concerve energy and cool faster!

Which is why the AC used to kick in even when it was cold outside if the sensor was reading 145 degrees f. My sensor is fixed so hopefully that shouldn't happen anymore.

Thankyou for the prompt response. I will give this info to my service advisor and see where we go from here. I will keep everyone in the loop for future inquires.

In addition I forgot to mention that exhaust system problems can give you these fluttering noiss. Loose attachments, pierced,broken exhaust pipes.that sort of thing
Hope good luck

Thanks again. It sounds like the purge valve because it does get louder after driving and it just started doing it the last month or so when it got colder.(Especially at night)
We'll let you know. Sincerely.

#495 of 886 All my speakers blew out at once!
Dec 30, 2005 (4:20 pm)
Hi, hoping someone can help.... I have a 2005 C55 AMG and today started up the car and noticed all my speakers are completely distorted, all sound like when you "blow them" like when you turn them up too high. Checked the fader and balance and all of them are distorted -
About 2 months ago I noticed the left front base - door - speaker was blown and was just going to go to an audio shop to get that pair replaced when this happened.
I never turn the radio up beyond normal "speech" levels and no other problems except a SRS airbag sensor warning that I am getting fixed in a week.
Any ideas? Is this a warrenty issue? Do you think they will try to weasel out of this and say I turned up the radio too high? I have the nav system with the upgrade audo by the way.
Thanks for any advice!
