Question about 2003 BMW 7 Series

1 Answer

Vibration Good day. At speeds between 80 and 100km/h my 730d goes into a vibration. I was told that it might be gearbox mountings that need replacing. Tyres are all balanced and wheel alignment is correct. Also from time to time the computer just kicks out. sometimes there is a 'cluck" sound. Everything on the dash goes dead and the gearbox puts itself into "safe" mode. When you turn the engine off and restart it the problem goes away !! Is this a common problem and how do i reslove this. The BMW people in my area has never heard of this problem so they cannot contribute. Thanking you Gert Wentzel

Solution in problem with the occasional when dash kick it and restart in Safe Mode - make use your car on I-BUS RESET. What vibration with gearbox covers, I do not think it will be bad gearbox mountings. I suggest to the transmission delete the current adaptation, what it learned the transmission unit - to factory defaults, this is the "0" value adaptation! Use a longer test road and the new adaptation have to loaded! Unfortunately, this operation is only diagnostic tools possible. It's a job for a professional garage

Vibration throughout car...change engine mounts, changed centre bearing, gearbox mount, changed both front and rear couplers still have bad vibrations


check for the drive joint phasing and angle setting of the center bearing
mostly with center bearing , the drive shaft has to be split and the flange removed for the bearing replacement
the flange can be put back on in any position and that will throw out the s joint phasing
Take it to a drive line specialist shop and ash them to check the phasing and angles to eliminate the vibration
The vibration could have been from a bad joint and the new joint was not properly installed which will also vibrate
If you are not familiar with the term phasing It is when the joints are in direct line with each other when placed on a flat surface and allows the differentiating speeds of the crosses as they pass through the 90 degrees to cancel each other out and stop the vibration
the drive line specialist will know and explain it better as he will have the drive shaft to show you on

I am burning oil alot (2006 outback 2.5) needs a quart within less than 3 wks (never see any oil leaks under car). With accelaration car also vibrates in gas pedal, seat and wheel -idoling is rougher than...


Trouble with modern day synthetic oil is that it evapourates very quickly, check to see what subaru say in the driver handbook about it, they should give you guidelines on how much oil the car should be using. Wouldn't think this was causing your vibration fault. Check gearbox and engine mounts,they may look ok but the rubber on them may be weak. Also check your anti-roll bar bushes.Good Luck.

What is wrong when vibration of chasis is noticed when driving at a low speed of 20-30miles per hour, whell balancing and allignment have been done


Please check if the engine mountings and the drvies are not wobbling at this speed. You must lift up each wheel and test for noise or wobbling of the bearings. Also assuming that your tyres are new , if not replace the tyres as there could be uneven wearing making this to react at slow speeds. You will need to check on the balance rods, the suspension springs / bushes and silencer mountings for any slackness. this might also produce the sympathetic vibration. Hope you get this right.Good day

Got a tough one: Tacoma starts vibrating only while accerating


I think its your gearbox as what you've saying is that you were drive with heavy moving trailer across the country and in the mountains it happiened i believe its friction rings in your gearbox what you've done calls RAPE GEARBOX i'll explane to you why

what is friction rings its a metal made rings inside your gearbox that are spinning. every time you switch your speed u said u've got 6-speed manual transmittion which means there are 12 friction rings on each of the speed + rear speed (R) now what happiens when you going up hill oil cerculation going faster as frictions spin faster but if you have not enough oil comming into the frictions then they start to rub on each other and they die thats maybewhy u have vibration

This is just my opinion

Vibration through the car Transmission-motor Linkage?


Check to make sure both headlights are tight,,,when it rattles at idle go feel the headlight and hold it and see if the noise and vibration goes away,sometimes the headlight has too much clearance and causes a massive vibration,,if thats not it try...loosening all the motor mounts and rock the car back and forth and them retighten them,it reseetles the mounts and sometimes fixes the issue,,also check the lower engine and trans mounts for wear.
