Well, either your customers had the intelligence to realise they had a
fuel injection problem and took their cars to a specialist, or you have
simply failed to diagnose a number of problems.  Even with the
relatively small number of cars I see, I've got two dead control
pressure regulators downstairs on the racks.  Next to the upper O-ring
in the CIS metering head, it's the least reliable part in the system.

Let's not pick on the control pressure regulator.  I don't think I
actually mentioned it in the original post.

          a) Fuel pump check valve (had ten of these bad)
          b) Cold start valve (two bad in the last year)
          b) Injectors (_NO_ comment on how many bad)
          c) System pressure regulator (one, so far)

Don't forget - this was a _specific_ response to a _specific_ problem.

I think I'm also aware of the checks to make on a non-starting Audi
engine.  Last Wednesday I went to an Audi dealership that has been
unable to start an MB ur-quattro for _THREE_ _WEEKS_ and started the
car in under a minute - bad manifold ground.  You can call the owner
on this one, if you like - I can give you his number.  The effect when
I walked back to the 'master technician' telling him I'd found in
less than ten seconds a problem he'd been trying to find for two+ weeks
was quite something, I can assure you.

And I had a 200TQ yesterday with starting problems that turned out to
be the three-way breather junction on top of the cam cover.

The original response was about starting problems that were occuring
around an hour after the car was stopped.  No problems at all when
cold.  None after a cool-down period.  No symptoms when running.

I'd like to know which hose has to split how much to cause these
symptoms.

I'm not - and never was - recommending that everyone with a starting
problem suspect their fuel injection system.
