[Biturbos4] Unholy smoke

[Chris Newbold]

As if the recent discussion here about dead lines on the trip computer
display wasn't bad enough (mine was fine until I read the posts and then the
next morning I started getting an intermittent dead line)...

Over the course of the last couple of weeks, my 2001.5 has gone from
emitting a small amount of grayish smoke on cold start (almost acceptable as
normal) to belching quite a cloud of blue smoke. More blue smoke accompanies
any significant prod of the throttle for 1-2 minutes following cold start.

Sigh. Something's just let go.

Because of the sudden onset I'm assuming this is a problem with a seal
somewhere, rather than something like valve guides. Anyone have any
suggestions? PCV system? Turbos (gasp)?

I'm covered by the extended Audi-Assured warrantee, but I'm sure they'll
deny there's really a problem unless I show them exactly what's blown...
