Default Bmw ABS and ASC Fault Lights!

Can anyone help? My abs and asc fault lights have appered on the dash,
after speaking to someone a bit technicle they told me it would
proberbly be a speed sensor! Can anyone tell me if this maybe true,
where its located, and could i do it myself? The car is a 523 (1988)
E39
Thanks!

There's one on each wheel near the bearing. Trouble trouble is working
out which is dead.

Yes, it is probably true. There are speed sensors on all 4 wheels. You can
do it yourself very easily, assuming you can change the brakes by yourself.
The trouble is, the sensors cost about $90 (USD) each, and they are
different for front and back. You need a system diagnostic to determine
which is needed. Since the traction control light is on as well, I'd take a
stab at replacing the rears before the fronts.

Most likely but could also just be wiring on them gone bad.

Excellent write-up Mr. Read.
Very detailed (end-2-end) and dummy-proof.
I've had the same problem (ABS indicator) on my 95 318i (126K mi) but
opted to live with it, thinking the repair-cost might be prohibitive.
Will give it a try.
Thanks a bunch !

time, will give that a blast and hopefully will be a bit of a cheaper
job than antisipated.....
