First and cheapest trick.... start the car, in park and at idle, turn the wheel lock to lock a couple times. Turn off car 30 sec, restart and see if trouble lights are out. This resets the steering angle sensor, an integral part of the ESP ABS systems. Not certain if it is also part of the presafe but I think it is.

Washing the board repeatedly with brake cleaner, followed by soldering the transistor back into place, restored normal operation. We have bought new transmission connectors for both our cars, and plan to change the fluid and install the connectors some day soon.
Not so satisfactory trip to indie....
VEHICLE IS IN LIMP MODE. CK AND ADVISE. CUST JUST BOUGHT VEHICLE AND WAS DRIVING
AND DROVE OK. NEXT DAY DROVE IT WOULD NOT SHIFT OUT OF 1ST GEAR.
CK AND ADVISE.
PULLED AND CLEARED FAULT CODES AND CHECKED ACTUAL VALUES AND FOUND NO
COMMUNICATION WITH THE TCM. FAULTS IN THE COMPUTER ARE CHECK POWER SUPPLY AT
CONTROL UNIT Y3/8N4 (FULLY INTEGRATED TRANSMISSION CONTROL (VGS) CONTROL UNIT.
NEED TO PERFORM FURTHER TESTING ON THE COMMUNICATION ISSUE. CHECKED FUSES,
POWER AND GROUND AT THE TRANSMISSION CONTROL MODULE AND ALL THESE ARE OK.
WILL NEED TO REPLACE VALVE BODY AND CODE TO CAR. POWER IS OK TO MODULE/VALVE
BODY BUT INTERNALLY SHORTED. THIS PART IS A DEALER ONLY PART. CUSTOMER MUST
TAKE VEHICLE TO THE DEALER FOR REPAIRS. CUSTOMER ADVISED.
