Vw new beetle abs light and three beeps after I fixed battery terminal. Brakes and fluid are fine. This happened after I fixed the battery terminal. Today [three weeks later], I disconnected the battery for 30 minutes to try to reset the computer. This did not work and after driving the car for 2 minutes at 25 mph +, the beeps and abs lights came on again. This is extremely annoying and I know this happened because of my fixing the car.
There is a fuse box on top of the battery. Find the 3 little green
fuses and check their contacts (remove one at a time and install).
If the fuses are OK, push on the harness plug that is attached to
those fuses, to make sure that the harness plug is sitting OK.
One of those fuses feeds the ABS. Using a test light to make sure
that power is going through the harness plug connector, is also a
good idea (as the connector may look/feel tight, but power/current
is not going through it).
