Haldex and tire wear

    Hello Guys,


    i have problem with my high tire wear on rear axle. I put new tires before 15tkm and front looks like new and rear are dead. Tires are equally wear. I have also bigger car consumption. I also have problems when the road is slippery or i rode over a canal or center line so rear axle seems to get slip or it feels like that rear axle is thrown sideways. I think that there is no any problem with haldex but i change oil and filter and no any change. It seems that there is some problem with rear differential that maybe is locked up under some condition or i do not know, because i tried to pull out the fuse for rear axle but without any change. I think that there is also some valve for the LSD but is strange that this problem is same even i pull out the fuse. No any DTC on dash.

    Hi Darry,


    this spring I had to drive with two diffrent tires on rear axle for some kilometers. above 130 km/h differential lock seemed to be engaged.
    I think my issue was caused by minimal tolerance in tire circumfence.



    Reflected to your issue:
    I can imagine that for any reason your EPS control unit gets wrong (but by system plausible) information on tire rotation.

    Yesterday we fully check car on diagnostic and no any problem found. I think that when there will be problem with ESP so i will get symbol on dash when the tyre get slip or something. For me is this system so much sofisticated to prevent any problem.
