Ticking sound under the center console? The faster I drive the more it ticks
Sounds like a baseball card in bicyle spokes flapping around.
Thanks

Crawling around the car I noticed that MB doesn't cut off the tails on their zip ties. WTF is that about?
The noise could be a zip tie tail touching a part of the driveshaft or U-joint.

If that doesn't work, search for "Drivetrain whine" - it was where we were all discussing differential problems.
It got so loud the other day we could not hold a conversation in the car. We are calling the dealer tomorrow first thing.
Raise up the center console, and it sounds horrific.

I know a few other memebers were having the same problem. I have contacted one and the others I don't have contact info from.
It did take 3 trips to the dealer and my wife driving around for 1 hour every day at lunch until the insulation would start hitting hte driveshaft making the sound so she could wheel in our MB dealer and let them listen. They finally heard it and finally took a good long look under the car. I guess they figured they didn't want to swap trannies.

Hope this helps. The sound was best heard with the center console open.

I'm having the exact same problem. The ticking comes only when the car is hot and it varies with road speed. It seems like it's coming from beneath the centre arm rest between the front seats.
Are you referring to heat shield touching the propeller shaft along the tranny tunnel or the rear wheel drive shaft? Thanks in advance

This guy is absolutely right. I had the exact same problem. No body could figure it out for the longest time. Then I read a thread on this problem and told the service advisor about it. They looked into it and fixed the problem. The older C-models have this problem. If your car was built in 2001 or early 2002, this is a potential problem that starts at 15000 to 20000 miles. Also be aware that the car needs to be running for awhile or under the hot sun for this problem to start up. If you take your car to the dealer fresh in the morning after its been cool overnight, they may not hear the problem and give the car back to you without fixing it.
How did they fix your problem? I sent my car in today, but couldn't find any part of the exhaust heat shield touching or close to the propeller shaft. The noise is still there.
It did take them 3 hours to figure it out once they finally admitted there was a problem. It got really bad right before they fixed it.

When I got it back the propeller head assembly was replaced along with a few other related parts. A few days later the tick was back... ugh so I brought it back and they messed with it again. I don't remember what they did but it didn't fix it. Third time they finally did what the original tech said was the typical fix (shave the insolation) and I haven't heard the sound since.
One of the many problems my 2001 C240 has had...
It will not hurt the car, and probably won't happen unless the car gets suitably warm... but you mine as well get it taken care of sooner rather than later.
Dumb story... I backed off a rock wall (don't ask) and a rock hit my exhuast pipe and caused it to bend the heat shield into my drive shaft. It made a terrible noise especially when going faster than 5mph, very much like a playing card stuck in my spokes. Drove it about 2 miles to the dealer going 5mph the entire way and no damage was caused. Your milage may vary. =)
