Hey guys, just had new front pads, rotors, calipers, and brake lines done. The shop had trouble with bleeding and so I now have a new master cylinder. Drove out of the shop and down the road. ABS light comes on and ESP is deactivated at about 50km/h. If I turn the car off and then back on, no warning lights. Warning lights come back on next time I am over 50km/h, so basically all the time. The car is going back to be fixed properly, but has anyone got a clue as to what the cause may be.
