Hi guys recently bought X5 3.0d facelift, wanted one for years and tbh it's my fave car i have ever owned and ive brand new 3 series etc, my issue is it's like it doesn't have traction, had the car about a month and went to turn the traction off to see if had better pull held the button nothing no light came on or anything, then even in my dash on ignition i can't even spot the light lighting up before they all go out again find it very odd, can it disabled completely? 

Cheers 

Hi Shapero

Welcome to the Forum 

Your X5 should have the 218 bhp engine a 6 speed ZF gear box with 3 settings Drive Sport and Manual originally it should get to 60 in around 8.5 seconds not many in it's class could live with that.

So your question is "it's like it doesn't have traction" is that a lack of power? Or a drive train issue? to be sure you need the codes read by someone with a BMW specific software to be sure and save yourself spending out on stuff you don't need to. Check all the fuses

You don't have traction control as such it is DTC Dynamic Traction Control which takes information from the ABS sensors (measuring wheel speed/slip) the steering angle sensors Yaw sensor and a few others I probably forgot. Holding down the DSC/DTC button for 20 seconds turns it off (but as it is computer controlled it never  really is off) 

If your trying for wheel spin don't waste your energy my 4.6is I upgraded when I rebuilt the engine some years back it was producing 450 hp (380hp at the wheels) on a Dyno. Acceleration was/is quick but No Wheelspin just launches
