Same rattle issue with the Mrs daily commute car... turned out to be them resonators, spot welding on defflecting screen inside had corroded badly and baffles had fallen off.

OK. Here's a new one. About a year ago, I dropped a peanut M&M which slipped between the driver's seat and console and seems to have lodged in one of the seat tracks. On short radius turns and steep inclines/declines, it rolls down the track and sounds like a pin ball machine. Cannot see it or access it. Any ideas?

Just remove the seat, 4 bolts and one harness to disconnect.

Can you offer a link to illustrations/assistance?

Look down at the seat rails. There is one bolt at each end of each rail, so they add up to 4 bolts total per seat.

OK. Cannot look until the weekend.

I just purchased a 2002 c230 kompressor with 18363 miles. I noticed, when driving home, that there is a slight rattle somewhere in the front end. It usually is more pronouced when hitting a bump etc. When driving on the highway, its pretty quiet, except for the supercharged 4 banger No warrantee in the car. I am actually looking for some type of warrantee extension. The car only has $18k miles on it for petes sake.

Just so everyone knows, I've un-stickied this because it is already in the DIY / AFTERMARKET MOD STICKY, in case you're looking for it.

Just bought my car 4 days ago. Right now its at the dealership for first 1k m check up. But I have a big problem with the seat belt adjuster on the driver side rattling. Any advice?

Thanks,

I took it off and put a piece of felt between the adjuster casing and the button. No rattles anymore for 2 years.

Awesome. Thanks man, I get my car back tomorrow so I will try it!

I'm now hearing rattling sound coming form the rear passenger. It happens when I'm just driving but very intermittent. Going over bumbs doesn't seem to make it happen. When it comes on it sounds like something in the tire hitting the fender well. Anyone have any clue what it could be?

aznmode

If anyone else is hearing rattle in the speaker, I was able to remedy mine by putting a piece of paper in between the plastic grill and the rear dash board that it's attached to.

Thank you so much for this post. I too hate noise when driving. Any idea on how to stop the squeak that happens when the SC engages on the s55 amg?

aznmode

Update. I finally figured out what was causing the noise. My windshield was replaced about a month ago and the roof trim that runs on the sides of the roof was coming off on the rear. So the trim was hitting the roof. I press it back in but it doesn't stay too long and eventually comes off again. Anyone know how to fix this?

EDIT: Was able to fix it. The tech that fixed my windshield didn't lign up the clips that holds the rear part of the strip.

Have search the forum for this one and found nothing so hopefully someone will be able to help (seen some good other stuff ref ticking though). Just bought a 2nd hand C270 sport edition 3 weeks ago, first MB and love it. It has just started a ticking noise (sounds like behind dash) which does not increase with speed and is audible between tick-over and 2000 rpm - about three ticks per second.It does it when stationary and moving, but stops when cornering or applying brake. Apart from the obvious like 'it is the brakes', which part? Car is still under dealer warranty so would help to know what I am talking about.

(W204 C200K)

i hear a knocking/tapping noise at idle and low rpm.. it seems to be coming from the back, as it is louder in the back than in the front. (its almost non-existant when in the front). During driving it dissapears, wen i stop at lights it starts up agen...

any help will be appreciated

Heres my fix:

1. Sell your south african built crap and never by a w203 again.

2. Buy a different Mercedes.

I'm already in progress of these two :P Completely fixes the rattles ahahha

Seriously though I've just had enough with the rattles and squeaks, it just craps me to tears, and in my mind Mercedes is dead to me, I'm downgrading to a w124. I have already seen threads with people complaining about squeaks from w204's. Need I say more.

Also heres proof of 204 rattle issues:

Hi all,

I have a C200 that has just started making a constant vibrating/humming noise when the car is moving. The noise sounds like it is coming from somewhere in the centre console. It sounds slightly louder if I remove the ash tray or open up the centre console armrest.

Other information:
- Seems to be coming from the passenger side (right hand drive car)
- Not the ticking noise from the dash - I have already had that
- Only happens when the car ir moving
- Does vibrate more/less when car is going faster/slower
- Handling of car does not appear to be affected
- Does not occur when car is still and engine is revved
- Becomes slightly quiter when turning a corner
- Cannot hear noise outside of car i.e with Window down
- Checked underneath vehicle and nothing seems loose. I did bend back part of the heat shield around the exhaust but this made no difference

After searching the forums I have seen it could possibly be one of:
- footwell flap
- purge valve
- stepper motor (but there is no clicking sound)

I was hoping someone might have some further ideas before I start pulling the car apart.

Thanks.

Loose insulation?

rmj

Hi samaritrey,

Thanks for the quick reponse.

Any idea where I should be looking, i.e. under the car or in the engine bay? I couldn't see anything loose...

can any1 shed any light on a knocking/tapping sound coming from the variable fuel pump.. mine (w204) seems to be really loud for some reason

I haven't been able to locate this problem. My car is fairly quiet most of the time except for three intermittent noises.

1. I noticed a pretty loud rattle when I shut the car off. It happens almost every time I shut it off and it sounds like it is coming from the lower engine compartment. I only saw one other post that was similar from an 06 owner who said they had a cat issue. Can someone elaborate on the cat issues or link to it if already discussed? That might be it here to, but I only hear it when shutting off the engine and sometimes if it's quiet I also hear it when going slow and pushing in the clutch. Been around a long time. I don't hear it when going over bumps.

2. When slowing down to a stop sign/light and putting the car in 1st to prepare to go again, there is a faint whining sound that I can also feel slightly in the shift knob. It's more severe the faster I'm going when putting the car in gear. Not sure what this is, but it's been there forever and doesn't get worse. I have had mechanics look into 1 and 2 with no luck.

3. This one must have to do with the new slotted Zimmerman rotors I had installed in the rear. Every time I brake there is a slight sound similar to having a playing card taped to your bike frame to hit the tire spokes. I'm thinking the rear pads are made for these rotors. Anyone else with this experience?

I think this car has been very solid and I'm just **** about these noises, so any help would be appreciated.
