Unfortunately, no.  Wish I had, would have probably saved me replacing alot
of the parts.  Did the (old boxey) 100 come with one?

So I'm probably best leaving well alone, and just change the filter more
regularly, say 5,000m until the problem clears.  I will regularly look at
the connections, to see if that horrible brown dust reappears.  My biggest
worry is ruining a new set of 150quid injectors, not to mention the 50quid
on second hand bits.

Should I bother with a krypton tune now it seems ok.  The man I now take it
to does have Audi experience, there is always one or two Audis parked
outside.  He also tested all the pressures, before the warm up valve failed.
All other settings (timing etc.) should be ok anyway.

Cheers,
