Power steering pump interchangeability for Audi

If it's hard to say exactly where it leaks, you may as well replace all the
seals.  What happens is they get old and brittle and no longer have the
flexibility to maintain their seal.  Fix one and you'll probably have
another start leaking next week.  All the O-rings and a seal for the shaft
come in the reseal kit.  The process is described well in the Bentley for
your car.  If you don't have it, I can supply the info.
