Hi
my A6 audi shakes in speed between 90-100 km. no problem in less than 90 and more than 100 . it is strange, anybody knows why?

thanks

I have a similar issue on my A4 1.9TDi (B5 model) between 60-70mph. I'd also be interested to find out the possible cause. It's not wheel balance as I've two sets of wheels and it happens on both (unless I'm unlucky to have 2 sets of incorrectly balanced wheels...)
