These guys are pieces of work (audi of Alexandria, VA).  Now the technician
calls me back and says its the rotor button and that the rotor did not
explode.  He said that the rotor button quits spinning and the timing belt
is loose which suggests that some teeth are missing and the engine is out of
time. In which case there would be head damage due to it being an
interference engine.  Total tear down could be 25 hours labor!!!!   Anyone
interested in a beautiful car.....$1000. 91 Audi 200 Quattro turbo sedan 20V
only 1600 made.

The distributor for the 20V (3B) is specific (as referenced below) and hard
to get, so double check you get the correct distributor not a 10V (MC)
maybe these are correct: 10V (MC): 035 905 206 AF
20V (3B): 034 905 205 Q
most other BTDT listers here will chime in with their experience.
It seems that the rotor under the cap (only one -rotor- listed 052 905 225C
but there is discussion about two, the narrower - rotor - being correct)

It seems however, that the post of yours talks about going into the motor
which leads me to think that the STEALER is soaking you for 12 hours of
labor, OR THAT the gear at the bottom of the distributor (plastic?), in the
motor, has broken.
If that's the case if could be a true 12 hour process just to open the motor
head to look around.

While I'm not experienced in that department, you may want to consider that
(Derek?) listers have had metal gears made for the bottom of there

If your a risk taker, go cap/rotor and new distributor after trying to shop
vac the plastic out of the distributor hole.  Then run a new one
(distributor - best w/metal gear you sourced) to see if you escape the 12
hours labor.

I'd recommend getting all the broken pieces out first.  Local wrench maybe?
Tell us what happens.  This info can be superceeded by a more knowledgeable
BTDT lister.

>>>>>>>>>> dealer states he
removed the distributor to see why it wasn't getting any spark and found out

that the rotor was in pieces.  The dealer suggests 12 hours in labor to
tear it down and check for further damage to the head etc

Your friend seems to be on to something here....I would do the same thing.
Just start with replacing the cap and rotor (cheapest route) and see if it
starts. At the end of the day, what damage was done has been done and I
think that just replacing those parts and trying to start will aggravate any

further damage, if any at all.  Make sure you use the correct rotor part for

the 20v turbo.
