Sixfan, before you start a single man crusade, or attempt to get a rise from me, use the search function - its your friend. I concisely answered the question of traction control 'switching off' a couple of months ago - Here is a copy and paste from that thread in the CAPA forums. "Just to inform anyone here that wants to know, the answer to continuously working traction control requires two changes to your program - 1) Torque Module Switch set to ON (1) 2) Torque Limit, Min Engine Torque Allowed table all values set to -1023 All dealers have already been informed of this...and now so have you! Its a 2 minute upgrade, so go get it." If these settings were carried out exactly, then your traction control would work as factory. All of the current distributed programs have this fix in place. However if your tuner has implemented changes in any of the above areas they may well have triggered the problem.
