Looks like you've done pretty much everything. I'm no expert but it looks like you may have run out of options. But however you may want to go to Tyrezone at Taman Mayang and ask them to do "road force (or something like that, I don't remember exact the terminology)" balancing on your tires. That may help. Good luck.

hmmm.... y your problem sound so familiar one ah....
0-80 no vibs
100 above no vibs .. rite?
my 2 sens...
check:
- long shaft balancing
- long shaft u-joints/couplings
- rear half shafts splines and bearings
- lastly, FD and Tranny
alternatively check... (maybe case...)
- engine mounts
- shocks bushing and tightening )
- balancing of tires (not on the wheel but properly done) and alignment
- tires screwed on tight?
- rim conditions (highly unlikely, but maybe)
- steering rack balljoints and bushings

I used to have but not on a Beamer. We call it "death wobble" in our terms as it is deadly as it vibs till the whole car is uncontrollable. Lotsa theories.. but normally it is wind up energy that the car encountered due to something that is not balanced/loosed and not channel out properly hence lasses out into the vehicle. How I solved it, serviced the steering rack and lower arms after cracking my head for some time.
no la... i dun haf this problem at the moment but i know someone has but not on a bmw...also got change almost the same stuff that you changed but still not sorted out yet. I think she will be taking it to the workshop soon.
Regarding the recommendation on the mechanic, go to the List of Good Workshop / Workshop threads in this forum that we go to. You should get an idea. However it is wise to let the mechanic check it out first before u jump to any conclusion as my 2 sens may be way off target

Just need to share with you,..
Have u check at that point..( blue color ) . That part (donno the name) coupling to long shalf. Inside there have a bearing. Any free play u feel there? That part can test and no need to open long shalf.
If feel free play at that point, ask mechanic to open and check.
Previously my car vibration also. but early problem it start sometime vibrate and sometime not. after it come worst, after 60km/h it will start vibrate. Check , than bearing hancur... MAYBE your bearing newly start to make a problem.
TQ
thanks for all your great effort to help. i have changed item no.1 and the centre u joint and the rear axial rubber joint, but didn't help. after that i took to a workshop in old klang road and they put in a second hand long shaft (but they adviced me to keep the old centre u joint so not to interfere with the long shaft balancing), the vibration is lessen but is still felt...sigh...could it be a gearbox problem, as my gearbox is somewhat screwed up, the error sign pop up a few times when i didn't warm up the car nicely in the morning...

No. What they do is actually try to find the "right" position between the rim and the tire. They will do normal balancing of your wheel and from the machine readout they will rotate the rim to a certain position to match the tire. It's kinda hard to explain but I hope you will solve your problem. You may want to drop by there and ask them to explain it to you. Gd luck
i get what you mean, i did it in one of the shop in old klang road, the housing garden behind heritage.tumbleweed said:
i notice that the vibration is most noticable when i apply throttle (during 80-100kmh), or when rpm is above idle. i did 160kmh yesterday, quite smooth at that speed.

Hi...
Please be carefull during send to workshop for test the solenoid. Mechanic will open gearbox oil sum and take off the solenoid to test. The test is using battery power connect to solenoid. Normally they will use loose cable from battery to solenoid +ve and -ve. During the test make sure u at shop and see how they test it. Takut masa test tershort and it will damage the solenoid. Elok2 tak rosak jadi rosak.
For me i will prefer during repairing the car, we at shop to see how they repair and test it. Just to make suke the thing done properly. Becoz the gearbox part is very sensitive part...rosak kalu banyak kuar wang. small solenoid is about 165 and the big one is about 385.
Just to share wit u.
TQ
