Hi All:

New member here...Just purchased a 2007 S6 and I have had nothing but vibration problems at highway speeds- over 60 mph. The dealership rebalanced all 4 tires and still didn't fix the problem. Then they ordered 4 new tires and while putting them on they scratched all 4 rims! So, they got 4 new rims for me and I had another company balance/install them today. Well, they did a road force variance test, etc... and the car is still vibrating terribly... Anyone else have the same problem? What was the solution?

 

Its still the wheels, its just hard to find anyone that knows what the hell they are doing on the tire machine/balancer.
Took me years to get it perfect.

 

I brought the car back again for the second time to an outside company (not the dealer). They calibrate their Road Force Machine, etc..every morning. They took all 4 tires/rims off again and redid everything. They said the tires/rims are spot on. However, the damn vibration is still there. It occurs over 60 mph when I take my foot off the gas (just rest it on the pedal) and barely hold the wheel. The vibration is most felt/seen when the wheel is turned slightly right or left. What else could be the problem? It is a brand new car- only 3 weeks old and the vibration has been there from the start!

Also, is there any way to turn off the AC/Heat? Or does it always only go down to 1 on the fan speed?

 

To turn off the A/C, just hold the "eco" button till it goes off.
My S6 doesn't have a vibration problem, sorry I can't help you there.

 

Go to the dealer and test drive another S6 on the lot and see if it does the same. If it doesn't vibrate, reek havoc and demand a new car.
