I have started to get a ticking noise from behind my instrument cluster that goes away momentarily when the brake pedal is pressed. This happens both whilst stopped and on the move. Anyone else experienced this?

ive experience a ticking noise also... mines only on the move.... steering column.. cluster area... somewhere behind the steering wheel... had the car in the dealer the other day, but as youd expect.... sounds was not reproducable......

Thanks. If you make any headway, I'd be grateful if you could update this thread.

i've also noticed this and have no idea what it is, it sounds like something may be loose and may be hitting against something else as it wiggles around or something, who knows, keep me updated and i'll let you guys know as well if i figure something out

There is no ticking noise at all coming out of my instrument cluster, but if I did have noise and was curious to see/hear what was living back there I would remove the instrument cluster and see for myself. You'll need to buy a the instrument cluster removal tools at the MB dealer (about $15) and pull it out. My neighbor had a mouse living in his, chewed through the cruise control wiring while driving. Finally trapped it with a lot of traps.

Got my 240 2 weeks ago, feel as if the ticking is coming from the glass covering the instrument cluster...maybe a little loose...going over bumps in the road it is slight, when I crank the bass on the stereo it really starts ticking...

The noise I had is at a steady rhythm. At first I thought it was a label on a CD hitting off of something as it spun round. I eventually eliminated that togethr with heater fan. It got really strange when I found out it went off when I pressed the brake pedal. I have even managed to replicate in with the key in POS 2 with the engine off.

I also have hear the same that you are teling twice. "I thought it was a label on a CD hitting"

Have you solved it?

Best Regards.

I found this answer on the net:

What It Is, Is A Electric Stepper Motor That Is Going Past It's Stop, Because Linkage That Connects It To The Hvac Flap Is Broken. The Most Common One To Fail Is The Footwell Flap Motor/linkage. This Is In Ignition Switch Area. Mercedes Offers Newly Updated Linkage Not So Prone To Breakage. Other Stepper Motor Positions Fail As Well, But It Is The Footwell Flap Motor/linkage 80% Of The Time.

Does it also happens when you have the air off?

Best Regards.

Moviela

Yes, even with the air off. Seems that when starting the car a computer moves the flap to find where is, then it moves it where the front panel switches tell it to go.

Got the same problem with mine and it's an '06 C230. It's been bugging the heck out of me whenever I drive it.

rubensans

Then I have the same problem and it's doing it anytime. When I start the car, after 45 seconds, after 30 seconds, after 2 minutes, after 15 seconds, etc....

Hi, I'm new to this forum. Just got my '05 C230 a few days ago. I just noticed there's an itty bitty piece of wood ( ) inside the instrument cluster which really annoys me and I need to get it out. How do you actually open the cluster? Is it hard, should I have the dealer do it? Thanks for your help.
