Hello!
My mother had a 2010 Transit Connect LWB that had been having issues since this spring.
The alternator failed on her causing the battery voltage to drop to zero and the car died. After having a shop replace the alternator, charge the battery and clear codes the ESP light was on intermittently.
She kept driving it and now the ESP light is on at all times. Removing the battery terminal over night does not work and I can’t find any faults on the OBD scanner.
Any pointers before leaving it at the dealer and spending a bunch of money?
My theory is that the ESP module didn’t like the low voltage and needs some kind of recalibration or adaptation. Could it be something with the SAS?
Thank you in advance!
