2003 beetle with ABS and brake light on. What should I do?
so all std brakes are good? pads, rotors and calipers? if not and are bad ABS goes mad, ABS is last to fix, not first OK>
abs can not hid for example, a brake caliper piston rusted to *****
after 19 years..old.(and will be that old I say how can it no be so?>)
all that and not one DTC posted (ALL) HERE ? amazing this...
and when you replace any part here, reset the all DTC now with the scan tool, buy one, you can not fix (diy) modern cars with no tool.
or rotor guide pins seized, fix the mechanical brakes first.!!!
they all must be good, end to end ,sure a weak pad (a tad) the ABS can hide it. well kinda. (normal wear yes, ugly no)
or take the car to a real brake shop and watch them and learn the craft and skills. or take An ASE brake course.
nobody here can guess what is wrong or done wrong, that be impossible other than a simple pep talk,.
