#58 of 61 Cricket Sound only when cold by y2kimmel Oct 16, 2009 (5:27 am)
Weather in DC has turned cold again, and my noise from the early spring has returned in my 2008 FEH FWD. It sounds like a loud, overcaffeinated cricket in the passenger side footwell. The noise begins immediately on starting the engine, and continues regardless of vehicle speed, engine speed, gas or electric mode, a/c fan on or off - basically it's just continuous regardless of what the car is doing. It only occurs when the temperature gets below 55 degrees outside. It's annoying as can be, and so loud that it makes listening to the radio or talking on the phone hard. The sound reminds me of a failing motor bearing. Is there some sort of small cooling fan in this area that is constantly on? Perhaps an electronics cooling fan? Please help - going nuts. I plan on taking the car to the dealer next week, but it's very inconvenient for me, and would like to troubleshoot to prevent a multi-day stay at the dealer.

Is there some sort of small cooling fan in this area that is constantly on?"   I hear this sound periodically, but it is most noticed when the windows are open. Try it, and I think you may find that the sound is really LOUD outside the vehicle. To me is sounds like something in the suspension, but I have not had it checked out. It is very sporadic on my 2008 AWD. Replies to this message: y2kimmel (Oct 16, 2009 9:15 am) whitey9 (Nov 21, 2009 7:57 am)

Thanks for taking a stab at it though. Replies to this message: whitey9 (Nov 21, 2009 7:57 am)

Replying to: y2kimmel (Oct 16, 2009 9:15 am) Blower motor bearing noise. Mercedes-Benz has a blower motor to cool the electronic control units IN the giant fuse box in the engine compartment. It draws air from the passenger compartment to cool the components. The blower motor that does this makes a "cricket" sound right behind instrument cluster, especially when started in the morning during cool/cold weather. The sound goes away after 2-3mins.
