The Audi 80 does not use a bomb (hydraulic accumulator).  It uses a
conventional vacuum-assisted braking system.  The pedal is supposed to
become hard after pumping with the engine stopped.  The bombs are only
found on the post-84 5000/100/200/V8 series cars and UrQs.

What your problem sounds like is the shift-lock solenoid (which prevents
you from shifting out of park unless you are stepping on the brake) is
not actuating properly.  Thus, it is not unlocking your shift lever.
This should be easily fixable.  From your description it sounds like
a simple adjustment of your brake light switch is all that is necessary.
