hi Lee,
The sound is driving me crazy everything when i switch off my Radio. i have changed all the door clip and the metal clip at top of the door 's panels. but the sound hasn't gone. would u mind to share how u fix the problem ? by the way, my driver seat also have some noise everytime i drive through the uneven road surface, can it be fix also ?
Hi Shyang,
I see from ur profile that u're driving an e36, 325. Great - at least we're talking about something in common.
Based on my subjective experience on my e36 328, here are my comments.
The e36 is a creaky car. In order to lighten the chassis, many more plastic parts were used compared with e30 or e34. This trend continues with e46 (and hence the common e46 power window failure, for example).
The more common creaks and groans are quite easy to fix. Your leather seat, for example, needs to be taken apart and greased up at every joint or point of contact.
Dashboard noises, unfortunately, would require a dashboard down job. Like Flash said, the next time you do a major service of your aircond requiring removal of dashboard, get the noise sorted then. Naidu does an excellent job.
Minor squeaks require a can of WD40 within easy reach, and a vigilant ear. Parts that would squeak include, just to mention a few :
1. glove compartment door
2. gearbox panel
3. aircond outlet duct frame
4. steering
5. the contact between the front leather seat and the armrest
6. seatbelt latch (that red piece of plastic where you fasten the seatbelt)
7. seatbelt rubbing against leather seat
8. door panels (this is an entire topic by itself)
Treat your squeaks like mosquitos and WD as Ridsect, and squirt away!
As for the noise coming from the back, a common weak point in the frame of a car is the B-pillar. As the rear passenger doors hinges on the B pillar, when the B-pillar flexes in relation to the rest of the chassis, the door will knock against the frame, near where the passenger's buttocks would sit. A strip of soundproofing material on the bottom rear corner of the door panel solved it for me beautifully. I sat on a friend's S-class, and lo and behold, heard the noise from the same part. I felt better about my e36 after that. Lildevil, not sure if this is similar to your case or not.
And finally, the mega creak solution. In pursuit of better handling, I FOAMED my entire car's chassis. This came with some soundproofing benefits. It took care of :
1. mysterious creaks deep in the dashboard
2. sharp creaks inside my roof lining
3. various assortments of clicks from a flexing chassis
To cap it off, I soundproofed my four doors, and under my rear passenger seat.
Now, the car is TOO quiet. I can hear the slightest microscopic noise. Killing one batch of noise simply brings out another batch at a lower decibel. Desmond says I should foam my ears next in order not to hear anything, ever.
I can also hear details from my stock standard stereo that I've never heard before. I save money on buying new CDs because I'm re-listening to all my old ones.
Another downside of too much soundproofing - I can't hear the cars outside. I reversed into a car at a parking lot once, despite her frantic hoots.
Now, the only thing left to soundproof is the roof. I can still hear the raindrops outside. Now, just waiting for my rooflining to droop so I can fix the roof up at one go. Maybe Desmond is right. Soundproofing my ears would be cheaper...
