Trunk Lock

You wrote:

I had a very similar problem to yours. My central lock would not
me to OPEN the trunk without using the key. I found out that
there is a
small springloaded "ball" encased in the plastic molded lock
The purpose of that ball is to allow the lock to be in either of
postions: 1; Always locked 2; Open/locked together with central

I think the problem was that since the casing is plastic, it wore
around the little springloaded ball, did essentially not provide
a good
"seat" for a precision part. I ended up drilling the ball out

Had the same problem _exactly_ and did exactly the same drilling.
Unfortunately w/o the ball the lock returns to the closed
position in about 2 min after the air bleeds out from the trunk
locking servo.

I ended up sleeving the drilled hole with a SS tube and
reinserting the ball/spring into it. It worked well for about 3
mos, but has stopped working about 2 weeks ago. I still haven't
opened the damn lock to see what happened this time.

BTW, this is a unique 100/200 problem coz they have plastic lock
components where the 5000 had all metal ones. One of those
"improvements" on the 200, you know... Marches hand in hand with
the brittle alloy clutch pedal on those cars. Evidently somebody
at Audi engineering did not like the idea that the old all-steel
5000 clutch pedals never broke.
