Hello,

I have a 2000 E39.

Tonight when I started the car, the "Service engine soon" light was
illuminated. The car seemed to be running fine. I started to notice though
when my foot hits the brake pedal the headlights will dim. It seem to get
more noticeable later.

What could be the problem?

Thanks,
Jeff

The Check Engine light means the computer has detected a problem and stored
a code. You need to find out what the code is.

Your car is OBD II (on board diagnostics, level 2) compliant. This means you
can buy a code reader at virtually any auto parts store for about the same
price as paying BMW to plug in the reader they have and pull the codes for
you, OR you can ask them at AutoZone to pull the codes or let you use the
scan tool and pull the codes yourself. AutoZone does this for free.

Lights dimming when you press the brakes sounds like the alternator isn't
charging properly.

More likely to be a wiring problem.

You might check your charging system and your battery it might have
lose connections/if it was the alternator it would do it when you
turned on or off any electrical appliance....

Nahh - if things were that bad he never start the beast.
It will likely be corrosion on one of the light units
