Hi, I'm Paul and I'm new to this forum. I'm turning to this board as really a last resort since I've not been able to find solid advice elsewhere and you guys here seem to be really knowledgeable.

I was hoping someone from this board would be able to answer a couple of questions I have about interior noises that the dealer has not been able to fix. The noises are really irritating and stand out, because the CLS is otherwise a very solid piece of engineering.

1. Vent noise/dash

When I turn the car on and as air starts to circulate, I get a variety flapping/clapping/suction/clicking noises eminating from the centre vents. Also, during take-off and braking I sometimes hear plastic moving behind the dash. The best way to describe it would be slight clunking. I'm almost certain it has something to do with the vents, but the dealer has no idea.

Has anybody experienced such odd noises?

2. Steering wheel

When I turn the steering wheel, it makes a slight, but constant noise. It's almost as though there were grains of sand in there somewhere. Also, on rough pavement, I get a metallic/plastic buzzing sound from the steering wheel. Dealer is unable to locate the noise, suggested replacing the steering wheel, which I think is nuts.

3. Various ticks and creaks from COMAND cluster/AC controls

It started this summer and I had the dealer take a look at it. They applied Krytox and some of it disappeared. It still creaks when my knee touches the side panelling, however. Does anyone know if there's a simple DIY fix for this?

4. Passanger seat shakes and rattles when emtpy.

If any of you guys have had similar issues and have been able to resolve them, I'd really appreciate a few pointers in the right direction. I really love the car otherwise, but it's the small things that end up ruining the general atmosphere.

Best regards,

Paul

Hi, no luck yet. Yesterday I decided to take care of some ticking noises from the centre vents and centre console panelling. I covered some clips and contact areas with MB special lubricant and felt tape. In doing so, I took out the centre vent piece and examined the inside of the dash. Everything looks perfectly solid, no noises when touching and nothing moving around inside.
