Dash Board rattle
 
Are any of you getting a rattle eminating from the centre dash? I'm getting one when i run on course chip surfaces eg M4 in sydney and it is driving me nuts!!! Not sure whether the dealership can help.

I had something rattle for a while behind the cluster area just in front of the windscreen, but it went away.

I had a bit of a noise coming from my windscreen, basically, every time i turned into my driveway and the right front wheel went over the gutter (the driveway bit not a full gutter) i'd hear a creak coming from where the glass meets the dash almost like the body of the car was shifting lol.....

I don't know if it is still there or not but my exhaust has certainly fixed the issue of me hearing it now lol

I agree with you, for the first time the other day on are really new rough piece of road I hear this little rattle. I tried to find it but no luck, it was in the centre of the dash somewhere. I thought about the dealership as well but I think the rattle would need to be there all the time first.

yea i got it to, do you have an exhaust?

Lord Kain 12-17-2009 12:06 AM

nope I'm stock, the funny thing is it doesn't happen all the time. Only on one road, I cant tell the service department manager to drive all the way down to this one road, they'll think I'm carzy.

Bloody hell, behind the cluster area too (EDIT--maybe, are you talking about the cluster of RPM, MPH, etc., or the voltage, oil temp, etc.? Mine is behind the RPM one.) And it usually (there are exceptions) only shows up under load at around 3000 RPM, i.e., at least 40 mph. My dealer is in an area with bumper to bumper traffic, so they think I'm crazy since I can't get it to rattle on demand at 20 mph.

I'm considering taking the damned dash off myself, even though I have no skills in this area. How hard would it be to get at the area behind the cluster? I've got a feeling it's probably just something that is loose.

BTW, this didn't start until after I put the FI exhaust on... it's loudest at right around 3000 RPM.

hhmm no noises like above here but today was in car with no music for awhile and i hear some kinda electrical noise sounds like its coming from the left door speaker...........wonder if it was always there or coz normally im pumping music i can't here it...............anyone else have electrical sounds coming from any speakers when no music playing? Only there when engine is running...........if i just push start and play music or have the system on no engine.........its not there

jekel - is it a high pitched noise? There have been a lot of posts about it.

High pitch noise coming from passenger side

That's just one thread I dug up but there are others.

So far I haven't noticed any strange noises *fingers crossed*

Same exact thing here ! At about 2500-3000 under load mine will make a buzzing sound from what sounds like behind the RPM cluster. Started after I installed my FI exhaust. Not blaming FI..just wierd.

thanks for that but nah not high pitched noise..........this one is not that bad and its bearable just few odd sounds now and then, real quiet.........cant really describe

Lord Kain 12-22-2009 10:05 PM

I just had my exhaust replaced and the rattle is there all the time now, next service they can attempt to fix it, lol.

I have a dash rattle in my G37 that is annoying.

No, of course it isn't FI's fault. Knowing a bit about speakers, I've picked up a feel for resonance issues, and given that I'm not the only one experiencing this exact problem, I'm thinking one of two things...

A. The sonic frequency which the exhaust puts out between 2500 to 3000 RPM is exciting a resonance mode in some part of the dashboard, causing it to vibrate like mad and bang up against something next to it.

B. The same as A, except it is causing a resonance mode in some loose part in the same area.

This is simply a rattle, it was there before my exhaust. It only happened on one piece of road, once I left it, it was gone. This was on a highway no change in RPM's just a section of road that he been repaired. Now after the exhaust even rolling along the road I get the rattle. My RPM would be no more than 2000 at the most.
