iv been noticing that these days my 530 has been weaving a lot it starts at bout 120km .. before it was still ok .. it used to be at round 180... but now .. its reached to a point where my friends in the can feel it too .... has anyone expericed this ? .. wha should i do ?

 

I understand early E60's fitted with active steering were difficult to keep in a straight line at higher speeds. I had one of the first production models and did notice this. Also it was stated by a number of car testers that the E60 suffered from side winds and tramlining caused by the runflats. Since I changed to my current March 05 E60 without active steering and runflats the high speed cruising is perfect.

What set up do you have? Runflats, active steering?

 

Tire pressure?

 

i have active stearing and runflats.. i dont know bout the tyre pressure .. does it haven when the pressure is to high or low ?

 

I first experienced weaving during lane changes when I got my R171 SLK 200. Before that I never felt it in my Peugeot 406. Now I drive a 520d automatic, and it weaves when going over the white lines. Is that what happens to you too or does yours weave even when not changing lanes? My father has an active steering 530i and his does not weave even at +200 km speeds. I guess it is a tire caused situation.

 

mine weavs while in a straight line when not changinf lanes .. should i reduce the tyre pressure of increase ?

 

the problem that you're likely facing with active steering and runflats is that you most likely have the dunlop DSST runflat tires. This exact combo on slightly grooved/bumpy/not perfectly flat road causes the steering to feel like it pulls to either side. I have this problem and always face it on imperfect road. It is a great pain but I dont think that anything can be done, other than changing to non runflat tires.


I'd prefer to have the security of runflats and a little pull than switching to non runflats. Plus the prospect of BMW changing tires for free is a great proposition.


Hope this helps

What is weaving? Lateral oscillations in straight line driving?

 

decrease tire pressure. weavin only happens to me, when the tires are over-inflated and running over white lines... Other than that, its straight.
