My car has 31,000 miles and yesterday, what I assume to be the
traction-control light came on and stayed on. (middle of the dash, triangle
with "i" in the middle, and an arrow going around the triangle) At the same
time, the warning indicators "BRAKE" and "ABS" came on. All are white,
rather than red. The car seems to drive normally. I assume some sort of
sensor has died. Can anybody suggest what might be broken?

Possible brake pad warning light on.

ABS sensor more than likely.

Based on the description of the indicators, the first lamp is the
ACS+T/DSC light indicating deactivation or malfunction of either or
both.

The "BRAKE" light indicates a DBC malfunction.

The "ABS" light indicates either ABS deactivated or a malfunction.

It's curious all 3 systems should be affected at the same time.
Assuming you have not had any accidents with the car I suspect there
may be a system malfunction, perhaps an electrical surge or perhaps
your battery is not working properly.

I would take it to the dealer, especially if warranty is still in
effect.

I believe if you lose critical sensors, then this affects multiple
components that depend on them (DSC, ABS, etc.). My 2003 manual
indicates that this combintation (DSC, BRAKE and ABS) is possible and
it more or less indicates, "The entire ABS, CBC, ASC+T/DSC and
ADB/ADB-X/DBC control system has failed". Car will handle normally,
however, you do not have ABS, DSC and other enhancements that
intervene to keep you on the road. Avoid hard braking if possible.

At 5 years old not sure what warranty one might have. It certainly
can't hurt to go in a and least find out what the initial assesment
is. Could be something as simple as a loose wire to a sensor. Good
luck!

Yeah, I missed the year model in the subject title. OTOH, it should
be covered by CPO or extended warranty. They are pretty common in N.
America.

These electrical system problems are definitely not something for the
average hobbyist to troubleshoot.

Thanks for sharing your information on sensor problems possibly
causing multi-system malfunctions. I have a PDF version of the E39
user's manual and curiously it does not mention this possibility.
However, what your manual says is very plausible. It's very unlikely
that the 3 systems' failures are not related. Perhaps RichK will
update us when he gets his car sorted out.

I will post back afere getting the car fixed. As I write this, I see that I
must have hit a wrong key in the title of the original post. The car is
actually a 1999 model, but still not under warranty.

You're not the only one with "fat fingers" - I had meant to type "it
could be covered by CPO or extended warranty..." rather than "...it
should be...". I think I need new glasses and to go on a finger diet.

Good luck with fixing the problem.

Well for what it's worth. My wife runs a new VW beetle and does absolutely
no miles a year (or very little). Strangely the traction light kept coming
on similar to yours. It was due for a service and was still under warranty.
I advised the garage that the light kept coming on and staying there.
When they serviced it the guy who was taking my service money said that as
the car did so little amount of miles they had to recalibrate the traction
control due to voltage/current issues that arise if the car is not driven
far or too often.
I was probably told a load of crap but maybe there is something in it.
