Hi Pete,
OK....got my feedback from the Motorsports guys...unfortunately it's not a Bosch system. So, I'm in the grass and heading toward the wall.
First question is did you try the extended hold on the ESP button?
An idea for you..... (for track use only...of course this need not be said) if you were to wire a switch in series to the Yaw Rate Sensor for which you could cut off it's power/communication to the ESP, the ESP system should go into what's called "back up ABS". In this mode it essentially works like an older ABS system (i.e. w/o the benefit of peripheral sensors). This should then afford you the ability to smoke the tires down to the rims and have fun drifting every corner of the track all day long. In theory of course....
. The YRS is likely located under the center console or under the dash in a central location. Vehicle CG is always target location so start from there and work outward. Once located, it should be a fairly easy test. Just unplug it and go for a drive (track or industrial park i.e. no traffic) and jump on the binders. Key thing to look for is that ABS still works and EBD (Electronic Brake Distribution), i.e. that ABS is able to balance the braking and the ass doesn't pass the front. Should be able to determine this with a couple panic brake stops. Doing it on wet pavement always works best. Then give the throttle a try to confrim the TCS is also disabled. If this proves successful, install a small switch in an inconspicuous place and your good to go.
Sorry I couldn't do more.......:shrug:
