I´m feeling the same and this is scary!! :(

My car is a 05 Boxster S with PASM

Has anyone come up with an answer to this problem? I have an 02 tt which is behaving similarly. Drives fine at slow speeds, drives fine when pushed a bit, but just cruising along on a long left hand turn the abs activates on what feels like the left front tire unsettling the car and the driver. The speeds are not at all high typically 50 ish ( happened while following a 80s Toyota pickup through the corner once- his car worked fine :) ) and it doesn't happen every time just a fairly high percentage on specific corners and always a left hand turn. If you push the car a bit in the same corner it's fine, which is what makes it so frightening. It happens when you are just relaxed driving.

No codes are visible with either durametric or and Indy shops program. An independent Porsche shop owner drove the car and had it happen to him, his words were to the effect that it scared the snot out of him an that it is not normal.

I have replaced and swapped wheel speed sensors and the problem never changed. I have inspected the wiring harness into the body and there are no signs of damage. Car has never been in an accident. Steering wheel sensor has been recalibrated with no effect. Suspension is factory, car has less than 25k miles. The car has oem wheels and tires in the correct sizes. Rears have less than 3000 miles on them fronts have nearly the same tread depth. Tires are contisportcontact 2s. The only snafu is that the fronts are not N-Rated. The rears are nspec. Rolling diameters are matched and there is no evidence of damage to any wheel or tire. Tire wear is even.

I called The dealer who told me that no codes means unlikely to find a fix as replicating the problem in their suburban location is nearly impossible-hmmmph

Anyone with any thoughts on what to check next or any experience? Yaw sensor is over a grand and I dont want to willy nilly replace parts unless they are needed. Love the car but am getting tired of looking at the trees on a left hand corner and wondering...

Thanks, Schmidty
