Actually Steve Powers found out that for his S6 the brake light would stay
on for a few seconds, maybe as many as 10. The dealer tried to fix it,
but the word back from Audi was that it was operating properly. This may
be BS, I'm just forwarding what I heard.
It turns out that Bentleys and Citroens use a similar hydraulic system.
There is a guy at work that is a big CX(?) fan, and he tells me that they
have pressure accumulators that can be recharged or rebuilt. I don't
know if it is possible to retrofit one of these units to an Audi. The
other thing to keep in mind is that there are different kinds of "bombs."
The one on my '83 urQ screws into the valve body and is very easy to re-
place. The one on the '88 5kCSQ appears to be a little more integrated
with the valve body. The 80/90Q may be different than both ...
If you have any issues with a system as crucial as the braking system
you really should seek out professional assistance.
