Just to ad to this, my car is still in ESP fault since May, all three lights on.
Dealer has the car again but are STILL STUMPED? The Starscan tool keeps telling them its the Front Left Wheel Sensor is at fault, they've changed it and it still says Sensor fault.
Anyway what im getting at is the 3 Fault Lights are on same as as what happens when you do this wire cutting mod but the ESP is still doing something.
When i was in 1st Gear Low Range off road and trying to slowly climb this hill the ESP was bringing on the brakes and reducing Power, so much so i had to turn around and go back down, it was that bad! It only happened on steep inclines and it didn't matter if i was going forward or reverse so there must be a sensor registering the incline.
Just wonder of those that have done this mod have they experienced any ESP interference still
