Jesse - I'd call the wrecker and have them take it in on the hook.
This is nothing to mess with. Worth $50 to save the car...
Is it possible this is one of those bad master cylinder problems in
which the fluid swells when the engine compartment gets hot - and
locks the front brakes? I remember discussion on this lately - and
that pulling one brake line at the master cylinder allowed diagnosing
the problem when fluid squirted out....
About Tom's posting on parts cost -
$300 is more than you should have had to pay for a PA - they are
available for less than that if you shop the vendor list.

Am I confused? I thought you had already replaced the bomb. If
It could be another component - perhaps the hydraulic pump. I'm
beginning to think they often mask each other's symptoms, and that
perhaps some of the PAs replaced are actually due to bad pumps. If
it's the pump, pressing repeatedly on the brake pedal keeps the
pressure low and will keep the warning light on. Try running the
engine with the brake off, and see if the light goes off - and
whether a quick pump or two on the brake makes it light up again.

For what part? The hydraulic pump? If so, WAY too much. You can
get one rebuilt for under $200.

Also try AudiOnly in Denver, 800/962-1902. Peter is a nice person to
PS: I'm waiting for a new supply of lifeblood (Pentosin) from
AudiOnly (for about $8 per liter!). When I get it, I will replace my
hydraulic pump. I have made my own pressure gauge to replace Audi
part #1441 and will post about the four-month diagnostic process I've
done - but I want that stuipd pump to be in place and be 100% sure the
problem is finally dead, with a stake thru its heart!!
