Wheel speed sensor 100%, had 2 go on mine (100k miles now). Can come and go intermittently. There are 4 of them located in each wheelarch. You need to hook it up to diagnostics via the obd to tell you which sensor has gone.Each wheel has one located in the wheel arch next to the brake sensor. Traction control cuts in like its mis-firing and then the comp realizes there's an error and shuts the whole system down, including the abs. Driveable but be careful in wet weather.
